FROM THE PUBLISHER
WELCOME TO ISSUE 140 OF SUBTEL FORUM, OUR SPECIAL GLOBAL OUTLOOK EDITION FEATURING A PREVIEW OF
SUBMARINE NETWORKS EMEA ‘25, AND HAPPY 2025!
We have been experiencing a polar vortex throughout a considerable portion of the US this month. Warmish temperatures for Christmas and the New Year have been followed by record pushing snow and ice, which from my vantage here in Virginia is always something to watch and experience. The usual runs on toilet paper, eggs, and milk that we typically see when such an event is coming have not been realized this time. Normally people are shopping up to the last second in order to acquire these valuable items to ‘survive’ the impending mother lode of a storm. But not this time. Maybe we have matured a little since 2020 and learned to take things in a little more stride.
In any case and in spite of the Arctic blast, we are still pushing ahead with some new SubTel Forum creations this year...

UNDER PRESSURE: THE GROWING IMPORTANCE OF SUBSEA CABLES AND DIGITAL INFRASTRUCTURES IN UN POLICYMAKING
BY CAROLINE CROWLEY, MELINA TISOPULOS, ANISHA SINGH, STEPHANIE GAY, AND ISABEL JIJON
This past September, the United Nations General Assembly (UNGA), the main policymaking body of the UN, convened for its 79th annual session. On this occasion, digital infrastructure was in the spotlight. The Assembly’s resultant Pact for the Future document incorporated matters of sustainable development and global governance, as well as a wide array of challenges and objectives. Among these, there was a strong emphasis on digital technologies and infrastructures in a subsection of the Pact known as the Global Digital Compact (GDC).
Shortly after the UNGA, country-level initiatives focusing on subsea networks also gained global coverage, with over a dozen member states signing agreements to address specific goals for developing infrastructure resilience. As highlighted in the recent major industry conferences such as the annual meeting of the Pacific Telecommunications Council (PTC) in Hawai’i and Submarine Networks World (SNW) in Singapore, this increased international focus on subsea cables and digital infrastructure has been driven not only by several recent and widely-publicized cable outages, but by the rapid rise of artificial intelligence (AI), growing cybersecurity and data security concerns, the need for equitable access to the global digital economy, and heightened attention to climate impacts. While the UNGA and member nations addressed the threats around AI, safety,
and equity extensively, the language around the environmental sustainability of digital infrastructure was relatively limited.
To date, several UN member states have implemented sustainability legislation for information and communications technologies (ICTs), using specific metrics, benchmarking, strategies and locally established programs to monitor and mitigate impacts, which is especially important given the ramping electricity usage of the data center industry. Still, the top-down prioritization from international agreements remains comparatively vague. Without robust sustainability goals and global coordination for digital infrastructure, progress could be fragmented and risks placing an undue burden of environmental impacts or mitigation efforts on developing areas, leading to potential sustainability blind spots. We believe that sustainability, alongside security and equity, deserves critical attention in global digital infrastructure governance.
In this month’s column, our undergraduate University of California, Berkeley research team, part of the SubOptic Foundation’s Sustainable Subsea Networks project, analyzes some of the UNGA documentation and the major priorities presented on matters relevant to digital infrastructure. The current international goals often foreshadow the direction of future legislation, especially when it comes to environmental and social
responsibility. As we show, while much of this goal-setting emphasizes government-industry collaboration for future policy design, there is yet a great deal to be done to facilitate the integration of environmental sustainability into the core practices of various digital infrastructure sectors.
DIGITAL INFRASTRUCTURES IN THE INTERNATIONAL SPOTLIGHT
The UNGA is responsible for establishing goals and resolutions affecting all 193 member nations, as well as approving the UN’s budget. As such, its resolutions carry significant weight on the international policymaking stage. Frameworks as significant as the UN’s 17 Sustainable Development Goals (SDGs) have come from this body, framing international policymaking, investments, and civil society initiatives since their official publication in 2015. Having this scale of international focus on the digital infrastructure industries, in particular on subsea telecommunication cable networks, highlights the growing perceived importance of and risks to the sector. Taking up over a quarter of the published Pact for the Future, the Global Digital Compact (GDC) tackles the issue of digital technologies, particularly AI, and associated infrastructure such as data centers and subsea cables. The document acknowledges the tremendous opportunities and benefits that these technologies can bring, especially in regards to pursuing the SDGs.
The GDC calls for international cooperation around objectives including the expansion of digital economy benefits to all, the development of a digital space respectful of human rights, and the enhanced international governance of AI and its beneficial uses. This focus is motivated largely by the changing landscape of the global digital divide, a key equity issue in an increasingly online world. While the global digital economy was valued at $14.5 trillion in 2021 according to the World Economic Forum, its benefits remain unevenly distributed. Nearly 2.6 billion people (one-third of the world’s population) still lack reliable internet access, particularly in developing nations, making fair distribution a key component of this year’s goal-setting.
The GDC also acknowledged the inherent risks that emerging digital technologies can bring, largely in reference to the understudied dangers posed by AI. Many of the UN recommendations here align strongly with the social justice-oriented SDGs, prioritizing the need for secure digital systems and governance that ensures the protection of human rights in digital spaces.
While not directly a product of the GDC, the UNGA was followed by several crucial initiatives on subsea cable resilience. The Joint Statement on the Security and Resilience of Undersea Cables in a Globally Digitalized World was signed just over a week following the Compact’s publication. The Joint Statement includes an agreement between 15 UN member countries and the EU to improve the resilience of global subsea networks. Key signatories included the United States, the United Kingdom, and Japan, among others. But more than just featuring nations that have been historically involved in subsea telecommunications
development, the Joint Statement included smaller Pacific nations such as Tonga and Tuvalu. The inclusion underscores the growing recognition of the unique challenges faced by small island nations in the global digital economy, many of which still lack the cable redundancy needed for a truly resilient Internet connection. Following this, the International Advisory Body for Submarine Cable Resilience, supported by the UN’s International Telecommunications Union and the International Cable Protection Committee, likewise drew together dozens of leaders from around the world to suggest practices that enhance the resilience of subsea cables.
providers that commit to transparency in their practices. This foreshadows greater involvement of governments in the cable laying and maintenance processes, a clearly expressed goal of the United States Bureau of Cyberspace and Digital Policy (CDP). This notion was echoed in a conversation hosted by Microsoft between CDP Ambassador Stephan Lang and Pacific Telecommunications Council president Bill Barney, wherein the goal was expressed that countries must prioritize their subsea networks as key areas of national defense.
Collectively, the span of September to December 2024 represented a significant expansion in the international
The GDC also acknowledged the inherent risks that emerging digital technologies can bring, largely in reference to the understudied dangers posed by AI. Many of the UN recommendations here align strongly with the social justice-oriented SDGs, prioritizing the need for secure digital systems and governance that ensures the protection of human rights in digital spaces.
More than just safety in purely digital spaces, though, country-level documentation following the Global Digital Compact called for legislation to enhance the security of digital infrastructure, especially subsea cables. Calls for diversified cable routes that prevent chokepoints and at-risk areas were high in the priorities of the multi-member Joint Statement on undersea cables. The solution proposed for improved future layouts was stronger risk assessment procedures, especially the careful selection of cable
dialogue on digital infrastructure resilience. But why now does the UN, as the global platform with the most visibility in policymaking see such an urgent need to dedicate a significant portion of its proceedings of the Pact of the Future to digital technologies? The urgency stems from a number of recent trends. The first and most prominent is the rise of AI and its yet-understudied impact on current and future Internet infrastructure systems. Predicted to grow three times faster than the entire IT market, the
SUBSEA
AI industry could hit nearly $1.3 trillion and hundreds of millions of users by 2028. Though recognized to hold great promise and potential for the fulfillment and development of some SDGs, there are also concerns on the utilization of this new technology. Conversations around ethics, equity, and energy use are appearing in news coverage and policy debates around the emerging technology, which remains largely unregulated at both national and international levels.
HOW DOES SUSTAINABILITY FIT IN?
In our analyses, we found, however, that sustainability was not addressed in great depth within the GDC, particularly in regard to the rising energy, water, and material usage by expanding digital infrastructure industries. A critical issue here is the growth in power draw for data centers, having increased 20–40% annually in recent years according to the International Energy Agency. This expansion, largely driven by AI, is accompanied by the risks of “con-
siderable strain” on local grids and delayed clean energy transition goals should centers be powered by carbon-intensive energy sources. National responses to this have been varied. Many nations lack the expertise at the regulatory level to optimally engage the sector and implement best global practices for enhancing sustainability and greening data centers. On the other hand, individual nations and cities have addressed the issue of sustainable digital infrastructure in recent years, such as the German

Energy Efficiency Act of 2023 and its encouragement of efficient hardware and renewable energy for data centers. Beijing data centers must reach 100% renewable energy by 2030 to avoid increased power tariffs.
Nonetheless, the GDC does initiate a discussion on the sustainability of digital technologies and supporting infrastructure. It is primarily framed, however, in terms of the potential of technology to enhance broader global sustainability efforts. The GDC promotes AI and emerging digital technologies as innovative solutions for ongoing climate problems and underscores that this can only manifest if the environmental impacts of these technologies are mitigated. Accordingly, it calls for integrating sustainability across the digital life cycle and designing infrastructure to mitigate environmental challenges. While the inclusion of these considerations contributes to bringing digital infrastructure sustainability to the global stage, the dialogue is noticeably sparse in comparison to the goal-setting on digital security and equity.
The GDC recognizes these are all interrelated issues: that digital technologies cannot enhance sustainability until the digital divide is addressed. The two go hand in hand; developing countries are disproportionately impacted by the environmental costs of global digitalization because of wealthier nations’ practices of material extraction and waste management. Yet, they have significantly fewer technological services and opportunities than the wealthier nations who employ unsustainable digital practices. Thus, the GDC recognizes connectivity as a
fundamental enabler for human rights and aims to establish resilient and sustainable internet access for all.
Environmental sustainability does, however, play a larger role in country level agreements. In the United States and United Arab Emirates Joint Statement on Strategic Partnership, published shortly after the Pact for the Future, the two nations call for investment in clean energy infrastructure to power AI. The Statement also promotes achieving a circular economy that uses refined recycling practices to enhance resource efficiency. While these goals are not included in the GDC, similar initiatives are reflected across other UN bodies. Over the last year, the sustainability and governance of digital technology and infrastructure has emerged as an area of focus within the broader UN system. For instance, the UN Trade and Development’s 2024 Digital Economy Report calls for a circular digital economy that addresses sustainability at each point in the digital life cycle. Efforts to address infrastructure in particular are also underway. The UN Environment Programme is creating guidelines on the green public procurement of data centers and global data governance. Similarly, the latest United Nations Climate Change Conference established the Declaration on Green Climate Action, which expresses a similar but more expansive iteration of the GDC’s notion of using technology to support sustainability. To ensure the environmental harm of technologies are addressed, the Declaration explicitly calls for reducing the energy consumption and greenhouse gas emissions from
the ICT sector as well as developing climate-resilient infrastructure. Such initiatives demonstrate that while digital infrastructure is not foregrounded in the GDC, it is increasingly recognized as a sustainability priority within the broader UN system. Not only is there more discussion around the issue itself, but also a rise of tangible efforts to develop and integrate globally and environmentally conscious solutions. This integration throughout the UN carries the potential for digital and infrastructure sustainability to be holistically addressed and set a uniform precedent for member nations to follow. STF

GLOBAL OVERVIEW: SYSTEM GROWTH
[Reprinted Excerpts from SubTel Forum’s 2024/25 Submarine Industry Report]
SYSTEM GROWTH
The submarine cable industry continues to adapt and evolve in the aftermath of the COVID-19 pandemic, with its long-term impacts becoming more apparent. While initial disruptions were anticipated to manifest in 2020 and 2021, the more substantial effects on project timelines and completions have unfolded in the years following. Projects already in the pipeline before the pandemic generally maintained momentum, but those still in the early stages faced considerable delays, impacting the pace of new installations.
It is important to recognize that the planning and preparation phase for submarine cable systems is often shorter than the subsequent installation and commissioning phases. Consequently, the number of completed systems in recent years has lagged behind pre-pandemic forecasts. However, the past two years have seen steady recovery, culminating in a notable resurgence in 2024, which recorded the highest number of new systems installed over the last five years.

Since the previous industry report, progress has continued across multiple regions. The year 2024 stands out as a pivotal year with 24 new systems coming online, reversing the downward trend observed since 2020. This surge in activity underscores the industry’s resilience and its continued importance in expanding global connectivity.
Over the last five years, the submarine cable industry has seen considerable growth across several regions, with EMEA leading in system additions, totaling 34 during this period. The Indian Ocean region, however, has lagged

behind, with only three new systems deployed.
2024 marked a significant increase in installations, with 24 new systems, the highest in this timeframe, reversing the general downward trend observed in the preceding years. In contrast, 2023 saw the fewest additions, with just 10 new systems deployed.
Comparing to last year’s report, where EMEA had added 35 systems over five years and the Indian Ocean was projected to add five, this year’s figures show a slight adjustment, particularly in the Indian Ocean region where only three new systems have been confirmed. The upward shift in 2024 indicates renewed momentum in the industry, especially in key regions like AustralAsia and EMEA.

KMS Added by Region, 2020-2024

When shifting focus to the total kilometers of cable installed, a different narrative emerges compared to the number of new systems. The correlation between the number of systems added and the total kilometers of cable laid does not always align. For instance, in 2022, 18 new systems were installed, contributing to a total of 140,000 kilometers, while 2020 and 2021 saw similar system counts but much lower totals of 44,000 and 52,000 kilometers, respectively.
In 2023, the trend held steady with a modest 35,000 kilometers of cable installed, in line with its low system count. However, 2024 marks a significant rebound, with nearly 200,000 kilometers added, driven primarily by major contributions from EMEA and the Transpacific regions.
EMEA continued to lead the industry with 63,000 kilometers of cable installed over the past five years, consistently
Planned Systems by Region, 2025-2027
recording the highest annual increases. Comparatively, the Transpacific region, while adding fewer systems, installed 24,000 kilometers, highlighting the disparity between system count and total kilometers installed.
Compared to last year’s trends, where the industry was still rebounding from pandemic-related delays, 2024 demonstrates strong growth, especially in terms of the total kilometers installed. This significant expansion in cable
infrastructure underscores the increasing demand for global connectivity and the strategic importance of both EMEA and the Transpacific regions in fulfilling this demand.
Looking ahead to the next few years, the focus of submarine cable deployments shows significant regional variations. The Transpacific region leads with a projected 65,000 kilometers of cable to be installed, accounting for over 32% of the total planned kilometers. This reflects a renewed emphasis on strengthening routes between North America, South America, Australia, and East Asia. The need to replace aging infrastructure, particularly systems nearing the end of their economic and engineering lifespans in the Pacific, is a driving factor for this growth.
AustralAsia is expected to contribute 47,000 kilometers, representing nearly 24% of future cable installations. Both regions demonstrate the increasing demand for robust connectivity across vast distances, underpinning their critical role in global data traffic.

In contrast, the Indian Ocean region has the lowest projection, with just 12,000 kilometers planned. This is consistent with its historical reliance on large, multi-regional systems to meet its connectivity needs, rather than standalone projects. The Polar region also remains a niche area for growth, with 17,000 kilometers of new cable planned, reflecting ongoing interest in extending connectivity to the Arctic.
Comparing this to last year’s forecast, both EMEA and AustralAsia remain key areas of future expansion. EMEA is projected to install 21,000 kilometers, accounting for over 10% of future planned projects, while the Transatlantic region is set to contribute 23,000 kilometers. Although these regions are not leading in terms of total kilometers, their steady growth continues to support global network resilience.
The projected figures for the Americas, at 16,000 kilometers, and the Indian Ocean, at 12,000 kilometers, follow similar patterns to previous years, where these regions maintained a more modest pace of development compared to the Transpacific and AustralAsia regions.
This outlook highlights the strategic importance of replacing aging systems and expanding routes in key regions, especially as demand for high-capacity, low-latency networks continues to rise globally.
Achieving a Contract in Force (CIF) status is essential for any submarine cable project, marking the point where the project moves beyond initial planning and enters development. This step confirms that contracts are signed and funds have been committed, making the project more likely to ma-
terialize. However, many projects face delays in reaching CIF status, often due to financing hurdles, which are exacerbated by the global economic uncertainty seen over the past year.
As of the 2025-2027 forecast, only 7 out of 34 planned systems, or 20.59 percent, have reached CIF status. This is a notable drop compared to last year’s figure, where nearly 48 percent of systems achieved CIF. The slowdown in systems reaching this milestone is largely tied to the current economic landscape, where financing remains one of the most significant obstacles.
The global economy has faced substantial uncertainty, driven by factors such as geopolitical tensions, rising inflation, and tightening lending standards. In 2023, banks significantly tightened lending standards to levels last seen during the global financial crisis of 2008, making it increasingly difficult for businesses to secure loans (Cúrdia, 2024). This, combined with ongoing inflationary pressures and economic shocks such as the war in Ukraine, has created a volatile environment for investment and project financing (Ahir, Bloom, & Furceri, 2023). Such uncertainty has played a critical role in slowing the progress of many submarine cable projects toward CIF.
As seen in previous years, projects that fail to reach CIF often struggle to move forward, as securing financing is a crucial step in ensuring the project’s viability. Although some systems may overcome these barriers in the coming years, others may face longer delays or even risk cancellation. The broader economic volatility only compounds these challenges, making CIF more important than ever in determining the fate of future submarine cable systems. STF

OUT OF SERVICE SYSTEMS ANALYSIS
An in-depth examination of the complexities surrounding the decommissioning of Out-of-Service (OOS) submarine cable systems reveals important insights into this evolving aspect of the industry.
Despite many cable systems exceeding their estimated End-of-Service (EOS) dates, the process of decommissioning often remains under the radar. However, recent developments have placed this issue back in the spotlight.
Companies such as Subsea Environmental Services, Mertech Marine, and Submarine Cable Salvage, Inc. have been at the forefront of addressing the challenges posed by decommissioned cables. Mertech Marine, for instance, has continued its long-standing efforts in the recovery and recycling of OOS cables, having actively participated in the recovery of multiple cable systems over the past year. Similarly, Subsea Environmental Services and Submarine Cable Salvage, Inc. offer innovative solutions that focus not only on cable recovery but also on environmental sustainability.
Publicly available data indicates that approximately 130 submarine telecommunications cable systems have been
taken OOS in the last decade, representing about 20% of all cables ever activated. While the prevailing practice is to leave retired cables on the ocean floor to protect marine ecosystems, high reclamation costs remain a significant deterrent for many operators. Nonetheless, the industry is seeing an increased focus on recycling and sustainability as environmental concerns grow.
Over the ten-year period from 2014 to 2024, a total of 411,000 kilometers of submarine cable systems are projected to go out of service globally. The EMEA region accounts for the largest share of this, with 105,000 kilometers decommissioned. This makes up a significant portion of global decommissioning, with AustralAsia following at 88,000 kilometers. Other regions such as the Transatlantic and Indian Ocean have decommissioned 70,000 kilometers and 61,000 kilometers, respectively.
The Transpacific and Americas regions, critical for longhaul connectivity, have also seen substantial decommissioning with 55,000 kilometers and 32,000 kilometers, respectively. The decommissioning trend underscores the lifecycle

Decommissioned Systems, 2014-2024
of these systems, many of which are nearing the end of their operational lives.
Compared to last year’s data, EMEA continues to account for the largest portion of decommissioned systems globally, historically responsible for over 65,000 kilometers since 2013. This regional dominance reflects EMEA’s position as a hub for many global subsea connections, but it also indicates the aging infrastructure in this region. AustralAsia, which also plays a significant role in regional connectivity, follows closely behind. In contrast, regions like the Americas and the Indian Ocean, while essential for certain routes, have lower decommissioning rates compared to EMEA and AustralAsia.
Technological advancements, while extending the lifespan of many systems beyond their expected End-of-Service (EOS) dates, have introduced additional challenges. Upgrades at landing stations and within data centers have allowed some cables to exceed the industry-standard 25year lifespan. However, as these systems age, they face increased risks of equipment failure, leading to more frequent service interruptions and eventual decommissioning.
Moreover, as regulatory frameworks evolve, several regions now mandate that decommissioned systems be properly removed or recycled, which adds to the complexity of managing aging infrastructure. The costs and logistics of reclamation efforts remain a significant barrier, particularly in regions where older systems are still in place but nearing obsolescence.
The global network continues to expand, and decommissioning and replacement of older infrastructure are crucial to
maintaining reliable connectivity. An estimated 85 systems are expected to reach their EOS within the next five years, with an additional 53 reaching EOS by 2032. Given that fewer than 60 systems have been decommissioned over the last two decades, this growing number of aging systems is a cause for concern across the industry.
Specialized companies like Mertech Marine and Subsea Environmental Services play a crucial role in the recovery and recycling of decommissioned submarine cable systems. These companies focus on acquiring Out-of-Service (OOS) cables, recovering valuable materials, and ensuring proper environmental management throughout the process. By providing solutions that repurpose or recycle decommissioned cables, they help mitigate the environmental impact of aging infrastructure and contribute to the sustainable management of submarine cable systems. Their expertise ensures that cables are responsibly removed from the ocean floor while adhering to environmental regulations and recycling practices.
In conclusion, the management of Out-of-Service (OOS) submarine cable systems represents a multifaceted challenge. Coordinated efforts between system owners, regulatory bodies, and specialized consultants are essential for making informed, sustainable decisions about aging infrastructure. With hundreds of thousands of kilometers of cables nearing the end of their lifecycle, the industry faces an increasingly urgent need to address both the technical and environmental challenges of decommissioning.

GLOBAL OUTLOOK: TRENDS AND OPPORTUNITIES IN SUBMARINE CABLE CONNECTIVITY FOR 2025
BY ERIC GUTSHALL
As we step into 2025, the global bandwidth capacity landscape continues to evolve, driven by technological advancements, increased data consumption, and shifts in market demands. From the financial centers of Tokyo and Chicago to the data hubs in Marseilles and Mumbai, submarine cables form the critical backbone of our hyper-connected world. This article delves into the key trends, emerging demands, and strategic developments shaping the industry across the Atlantic and Pacific oceanic corridors that United Cable Company has observed as brokers for over nearly three decades in the bandwidth brokerage business.
THE STATE OF GLOBAL BANDWIDTH CAPACITY
Global bandwidth capacity has surged over the past decade, driven by explosive growth in data-intensive applications such as AI, video streaming, and cloud computing. Hyper-scalers, including Google, Amazon Web Services (AWS), and Meta, continue to drive demand for high-capacity, low-latency routes to support their sprawling infrastructures.
The Atlantic corridor remains a critical artery, connecting major data and financial hubs in North America and Europe. Pricing trends in this region reflect robust demand, with some routes commanding rates between $3,750–$6,500 per MRC* for
a 100G link between NY4 and LD5. In contrast, financial low-latency routes—such as the 10Mbps connection between the CME (Chicago Mercantile Exchange) and LD5—can cost $150,000 per MRC for <63ms latency, with rates exceeding $325,000 per MRC for <59ms at the 10G level.
The Pacific corridor, spanning routes such as Los Angeles, San Jose, and Seattle to Tokyo, Hong Kong, and Singapore, shows significant pricing variability. Bandwidth offers for 100G links priced between $15,000 and $19,250 per MRC, while 10G links range around $3,750–$5,000 per MRC. For instance, the PC-1 cable—one of the Pacific’s major transoceanic systems, although the cable is nearing its end of life (with only 4-5 more years of usage) with the advent of Topaz cable will replace PC-1 and there is always the reliable TGN-P
cable. All three of these cable are primarily used by Fintech firms.
Latency performance on these routes has become a key differentiator. For example, the Tokyo (TY2) to Chicago (CME) route boasts an impressive 118.7ms latency, making it highly sought-after for industries requiring ultra-fast data transfer, such as high-frequency trading and fintech. A 1G connection on this route can command a price between $6,000–$11,000 per MRC, while 10G is now rare and no longer available in the marketplace. Previous 10G units were sold for between $13,000 and $30,000 per MRC.
*Note: MRC = Monthly Recurring Charge
ATLANTIC VS. PACIFIC: MARKET DYNAMICS AND TRENDS
While the Atlantic corridor remains the most mature market with


relatively stable pricing, the Pacific region is seeing greater diversification in cable systems and pricing strategies. The Transatlantic route, which boasts the first cable built in the 1850s, continues to lead in overall traffic volume. However, increased demand from Asia and the rising need for more submarine cables, lower MRC price points, and reduced equipment costs are contributing to the shift in market dynamics. These factors highlight the growing demand from Asia-Pacific economies and their integration into global markets. We continue to see trends in the Atlantic for 100G and/or 10G wavelengths are one third of the cost of traditional Pacific routes of the same capacity.
Major data hubs like Tokyo, Singapore, and Hong Kong serve as critical nodes for data transfer and as strategic
drop-off points for distributing IP traffic, often acting as major financial hubs. These hubs are linked to subsea routes that stretch westward to Marseilles and Mumbai. Marseilles and Mumbai also act as “drainpipes” for Trans-Pacific traffic and redundancy, stabilizing high-capacity data flows between the Atlantic and Pacific systems. Marseille is quickly evolving into the new world hub from London for diverse connectivity with 22+ submarine cables by the end of first quarter in 2025. A typical 10G from Singapore to Marseilles on PEACE, AAE1 or SMW5 is $3,750 MRC or $19-$22K on 100G.
Emerging routes to secondary markets, such as Jakarta, Chennai, and Cape Town, are also gaining traction, reflecting an increased focus on expanding global connectivity beyond
traditional financial hubs like Frankfurt and Milan.
DRIVERS OF DEMAND: AI, FINTECH, AND SOCIAL MEDIA
Several key factors are fueling the surge in demand for submarine cable capacity:
1. AI and Machine Learning:
AI-driven applications require massive data processing and storage capabilities. Hyper-scalers are investing heavily in dedicated routes to support AI workloads, connecting data centers across continents with low-latency, high-capacity links. i.e. Tesla is a prime example in the U.S., with traffic from a single site exceeding nearly 20 Terabits for AI, shared across four U.S. carrier infrastructures.
2. Fintech and Low-Latency Markets:

High-frequency trading (HFT) and cryptocurrency exchanges depend on the fastest possible routes to major equity centers like Chicago, New York, New Jersey, London, Frankfurt, Marseilles, Milan, Mumbai, and Singapore. Low-latency connectivity has become a critical requirement, driving innovations in route design and the establishment of financial exchange locations, including the use of wireless longhaul options (Microwave, Millimeter-Wave, and Free-Space Optics in metro areas). Innovations in fiber optic technology, such as hollow core fiber for short metro extensions, further support these needs.
3. Social Media: Platforms like TikTok are driving exponential growth in video traffic for apps and web-driven platforms, requiring robust infrastructure to handle high-bandwidth demands. These platforms also benefit from proxim-
ity to AWS data centers and other cloud service providers that support their global reach.
4. Entertainment Content Delivery and Cloud Computing: The rise of 4K/8K video streaming, virtual reality, and edge computing underscores the need for resilient and scalable submarine cable networks to support international content delivery and live events. Both 4K and 8K streaming require substantial bandwidth to deliver high-quality video content; “higher” in this context refers to even higher resolutions like 16K, which is still in its early stages of development but will demand even more bandwidth. Streaming and broadcast services will continue to drive this development, with organizations like Amazon, Apple, Microsoft, TikTok, Zoom, Google, and Netflix leading their respective industries. A typical streaming handheld device requires around 5

THE CARRIER GUIDE TO 2025
TRAFFIC, TECHNOLOGY AND UNSUNG HEROES
BY MATTIAS FRIDSTRÖM
According to the Chinese Zodiac, 2025 is the Year of the Snake. In Chinese culture, snakes are associated with wisdom, charm, elegance and transformation. They are intuitive, strategic and intelligent. In many ways I can’t help of thinking that this is exactly how telecom companies need to be in 2025. With continued geopolitical tension and tough market conditions, the only way to stay relevant is to adapt. We must use all our wisdom and transform ourselves into a better version of what we are today. With the support of AI, we need to carefully transform our operations, while keeping our customers happy and our networks up and running. But in spite of all these challenges, traffic is still growing, and new opportunities continually arise. In keeping with our traditional ‘Top 3’ predictions for the year ahead, here are a few thoughts for 2025.
THE TOP 3 GLOBAL CARRIER INDUSTRY TRENDS
1. Five ants are more than four elephants. This was the name of one of the most popular shows in Swedish television history and in many ways, it is a fitting metaphor for today’s Carrier industry. More route diversity means a better protected network and greater performance. With today’s turbulent geopolitical environment, operators must protect their networks as much as they possibly can and the best way of doing that is to deploy as many routes as possible between any two locations. The large “elephant” routes are generally more economical, but also far more vulnerable when faults do occur. A multitude of smaller “ant” routes can be more expensive to operate but provide greater resilience overall. During 2025, we will see many new routes added - even routes that have previously been deemed not to be financially viable.
2. AI gets the power. It is widely agreed that AI is here to stay and in future, most companies will take advantage of it in some way or another. This means that data centers hosting GPUs and other AI related equipment will need enormous amounts of power - the greener the better. When you ask AI companies about their priorities, power comes first, second and third on the priority list, with connectivity a close fourth. While it still is not clear exactly how AI will impact long-distance traffic, operators will need to evaluate the business case for constructing new fiber routes to areas where there is a lot of power, but not much connectivity. Will it really be worth connecting to these remote data centers, or should that be left to the regional players?
3. Sustainability initiatives may finally happen. For many years, operators and enterprises have been telling the industry that green initiatives are on their agenda - with many customers saying that they are prepared to pay a premium for greener services. In turn, carriers have candidly published ambitious sustainability targets, but at the end of the day, few customers have really been prepared to pay more for sustainability, and little has changed. Cost is still the most important selection criteria for network buyers. During 2025, companies will be under pressure to report their sustainability KPIs and there will be greater focus on this area. CSRD, ESRS, and SEC climate disclosure rules, together with EU Taxonomy are buzzwords that will really matter in 2025.
THE TOP 3 TECHNOLOGY AND TRAFFIC TRENDS
1. C and L join the band. Now we’re at Shannon’s limit, we need to find new ways of increasing our optical footprint - a particular challenge where fiber is a scarce resource. During the last couple of years, our industry discovered the possibility of using part of the optical spectrum known as the L-band. It still takes some effort to add L-band usage to operational C-band systems, but it is by far the best way to increase capacity when your underlying resource is only a single fiber pair. During 2025, we will see more projects that make use of both the L and the C-band, and with any luck, the implementation process will become a lot simpler (and less costly) over time.
2. MOFN is back. Ten years ago, in a marketplace where knowledge about running global networks was a rare commodity, managed network sales were pitched as the land of opportunity for carriers. Essentially, this came down to leasing out fiber pairs and equipping them with optical gear for a comprehensive managed network solution. As time has passed, however, spectrum and other optical solutions have gradually succeeded this approach. We are now seeing the return of the managed network but under a different name - Managed Optical Fiber Network. High-capacity needs but limited human resources mean that some businesses are again asking operators for MOFN solutions. During 2025 we will see many more of these solutions.
3. IPoDWDM for real. Some operators tested the new 400G ZR technology already back in 2021, and since then, the technology has really matured, with standards coming together even for 400G ZR+ pluggable components. The huge CAPEX savings combined with a lot less OPEX when power usage falls is the main driver
FEATURE
here for operators. There are still some operational issues to resolve, but during 2025 many more operators will start using this technology either to connect more locations with their IP networks or simply just transfer their current IP core network to something far more cost-effective and scalable.
THE TOP 3 FIBER INNOVATIONS THAT NOW SEEM POSSIBLE
1. Hollow core fiber. Hollow-core fiber is a promising innovation for Internet carriers as GenAI accelerates. This type of cable allows operators to transmit light through an air-filled core, rather than glass fiber - enabling higher speeds, lower signal losses and other improvements that support the connectivity requirements of emerging applications. Hollow-core fiber currently faces production scalability and cost challenges which inhibit widespread implementation. It’s a compelling innovation but it comes with a hefty price tag if used to replace large legacy networks. Still, the industry may yet overcome these obstacles eventually and begin wider deployment within the next few years. During 2025 we will be hearing more about this great opportunity.
2. Multicore fiber. There are still many places where space is limited and where pulling-in thick multifiber cable is simply not feasible. Multicore fiber is optical fiber that contains multiple cores within a single strand. It is possible to transmit much more bandwidth while retaining the same form factor and size of the cable. It is widely used inside data centers between switches, servers and storage devices but is yet to reach long-distance networks. With Shannon’s limit already here, there will be an increased demand for new fiber everywhere and we might see some use cases in long distance networks where a multicore fiber cable could be used within a legacy duct infrastructure.
3. The fantastic plastic dream. Plastic fiber has been around for a long time and is widely used across short distances, with the main advantage being lower cost per meter. There has never really been a viable use for plastic fiber across long distances due to attenuation and dispersion limitations. Long-haul deployment of cheap plastic fiber is in many ways a pipedream in a world where we will need a lot more fiber everywhere. There is a common misconception that everything will be wireless in the future - in reality, wireless and wireline will coexist to deliver the unique benefits of each technology. While cheap plastic fiber used across long distances may still seem unrealistic in 2025, we can always keep our fingers crossed for a technological breakthrough.
THE TOP 3 BEST ENHANCEMENTS WITH AI FOR A CARRIER
1. Predicting faults. Networks are currently churning out operational data that is often not used (or not possible to use) for operational efficiency enhancements. It isn’t a new idea to use historical data trends to predict when the next equipment failure may occur, but with the use of AI & machine learning we are now closer than ever to a practical solution. By applying intelligent analysis of high volumes of operational data - such as temperature and processing efficiency - within a short period of time, operators should be able to identify the anomalous behaviour that can predict the likelihood of future hardware failure within a reasonable margin of error. If, for example, a network card can be proactively swapped-out before it fails and customers do not notice, we will have all won a significant operational victory. With AI now a reality, there are many reasons to believe that this will start to happen during 2025.
2. More speed and transparency. Most Operators have many customers. Often, when a fiber cable goes down, many customers are affected at the same time and they all want to know every detail about the failure, time-to-repair and the service resolution. With the support of AI, good trouble-ticketing and network inventory systems, operators should now be much better equipped to provide customers with more useful information during an outage. Many operators today still rely on manual routines, and the few that have become more automated are usually regarded as less customer friendly. Most customers end up calling them anyway when they do not understand the automated information they receive. During 2025, good customer experience will still be critically important, but AI will help make it better.
3. Hands off! The Carrier industry has for years been extremely manual by nature. Poor data quality in combination with complex workflow tasks has made automation difficult. With new AI tools, this now seems to be something the industry can overcome, and we can finally have workflow engines driving processes without the human touch. We still need very accurate data but with the support of AI, operators can do much more than they could before. Faster and more accurate delivery flows mean that operators can deliver services sooner, making their customers happier. During 2025, a lot of focus will be on speeding things up.
THE TOP 3 THREATS YOU NEED TO PROTECT YOUR NETWORK FROM.
1. The weather. Our industry has recently made significant progress in fostering collaboration between network operators, infrastructure owners, regulatory authorities and industry traceback groups in successful resistance to DDoS attacks. While these efforts seek to combat malicious traffic flooding our network servers, what about the natural disasters flooding our physical infrastructure? Unfortunately, extreme weather events significantly disrupted global communications in 2024 and while many service providers are only beginning to discuss weatherproofing network infrastructure, even fewer are actively implementing effective weatherproofing strategies. As climate change escalates, these contingency plans (or lack of them) will enter the spotlight in 2025. While we still have much work to do, possible enhancements may include deeper collaboration with authorities to leverage advanced geospatial monitoring systems and help us to anticipate natural disasters. More care when evaluating potential network sites will also prove crucial. Traditionally, operators viewed forests as sufficiently safe and remote for the deployment of fiber optic cables. However, with more forest fires, service providers will need to be more thoughtful about where they dig fiber and may need to bury cables deeper in vulnerable regions.
2. Anchors. The world’s oceans are criss-crossed with sea cables and there are many more to come. Traditionally, fishermen have been the sea cable’s worst enemy, but recently we have seen a number of cases where cables have been broken in odd places with large cargo vessels too close for comfort to the actual break. Sabotage or not, it clearly shows that operators will need even more cables to sustain a reliable and resilient network that can work even if multiple cables are cut. For years operators have worked to find the shortest and best routes for their traffic but in future, we need to combine this with routes that enhance geographical diversity. During 2025 this will be hotly discussed and some older or soon-to-be retired cables will be given a new lease of life. Recycling is the way forward in 2025.
3. Cyber-attacks. Unfortunately, with the volatile geopolitical situation we currently have, we will undoubtedly see an increase in DDoS attacks across all geographies. New attack vectors are emerging and attacks originate from new sources. Carpet bombing attacks have been particularly popular during the 2024. The positive thing here is that both systems and operators are becoming better at fighting off attacks. A large number of attacks are currently
stopped before they even are noticed thanks to the collaborative efforts of larger Tier 1 IP backbones to stop them. AI will certainly help attackers find new weapons for their arsenal, but at the same time, operators are using AI to develop new mitigation techniques. This ongoing power struggle between good and evil will intensify during 2025.
THE TOP 3 UNSUNG HEROES
1. The billing administrator. Sending out invoices is normally a fairly straightforward task. But issuing correct invoices in a world where things change very fast, where traffic goes up and down rapidly and deals are done to correct past mistakes, can be a real challenge. Add to that customer consolidation and billing becomes a dark art. Without our fantastic billing administrators this topsy-turvy industry would be even more chaotic.
2. The cable coiling guy. The world needs more submarine cables, but without someone to follow a cable when it is loaded on to a deployment vessel, there wouldn’t be any submarine routes. Walking several kilometers in a tight circle to make sure the maximum possible amount of cable is loaded on to the boat is no mean feat.
3. The corporate AI police. With the introduction of AI comes endless possibilities to improve what you do. But also, the unlimited potential to make mistakes much worse. It might make sense to ask your favorite AI program to take minutes from your strategy meeting, but within minutes, the whole world can read them on the Internet. Company AI law enforcement police is neither a popular nor easy task.
Predictions are, of course, just predictions, and we wish everyone in the telecom ecosystem – from our business partners in the network to end-users and everyone in betweena brighter year ahead, with good health and prosperity. One thing is certain, 2025 will be a year filled with excitement and change, but as we always say here at Arelion, “You can’t predict the future, but you can be ready!” STF

THE HIDDEN LIFELINES
Subsea Cables, Maritime Security, and Cybersecurity Under Global Scrutiny (A Reflection)
BY JOSÉ AMARO





Every time we send an email, browse social media, or join a video call, we’re relying on a vast, hidden infrastructure beneath the oceans—subsea telecommunications cables. These critical cables, stretching thousands of kilometers across the seafloor, carry over 97% of international internet traffic, acting as the digital world’s lifelines. But as the global economy becomes more interconnected, these cables are increasingly vulnerable to threats.
Recently, both Europe and the United States have ramped up efforts to protect subsea cables from both physical and cyber threats. The European Union (EU) has implemented the NIS2 Directive[1] and theMaritime Security Strategy[2], placing subsea cables at the heart of their critical infrastructure protection. In the U.S., agencies like the Department of Homeland Security (DHS) and the Federal Communications Commission (FCC) are increasing measures for cyber and physical defence, especially after recent cases of damage and espionage involving these vital systems.
However, the dangers to these vital networks are growing. In August 2023, a major incident occurred off the coast of Cameroon, severely damaging the West Africa Cable System (WACS) and South Atlantic 3 (SAT3) cables. This caused widespread internet outages across Cameroon, Gabon, Congo-Brazzaville, and the Democratic Republic of Congo. The disruption, reportedly caused by a rockfall, took several weeks to repair, illustrating the fragility of these essential links and their vulnerability to both natural disasters and potential sabotage.
This incident follows a series of threats to submarine cables, ranging from attempts to sabotage Arctic submarine cables (2019), to cyberattacks on landing stations (2021) in the US and Europe, to physical sabotage in contested regions such as the South China Sea. The 2022 incident, which involved the mysterious cutting of two cables near the Shetland Islands, is another clear example of how even apparently remote cables can become targets. With these events in mind, the need for comprehensive protection strategies is more critical than ever.
tems such as YARIS, IORIS and SEAVISION traditionally employed to combat illegal activities like illegal fishing, piracy, and drug trafficking, can be adapted (if they aren’t already!) to monitor and protect critical submarine cables. By utilizing AIS satellite technology, these platforms can track vessel movements in real-time across open waters, enabling authorities to swiftly detect unauthorized vessels near sensitive cable routes. Continuous surveillance helps identify suspicious behaviors, such as vessels lingering near critical subsea cables, which could signal potential threats. This proactive approach enhances the security of these critical infrastructures, ensuring that authorities can intervene before any damage occurs.
Along coastlines, the combination of AIS and RADAR provides an even more detailed picture of maritime activity. By monitoring both the surface and the surrounding airspace, authorities can detect potential risks at key points like landing stations, where cables transition from sea to land. This area is particularly vulnerable to both physical attacks and espionage, as it’s often the point where data can be intercepted if security measures are weak.
On the other hand, one of the most interesting advances in submarine cable technology is the development of so-called SMART (Sensor Monitoring And Reliable Telecommunications) Cables. These cables do more than just transmit data; they are also equipped with sensors that actively monitor the environment around them.
Beyond monitoring, artificial intelligence (AI) adds a powerful layer of protection. AI algorithms can process vast amounts of data from AIS and RADAR systems to detect patterns of behavior associated with illegal or threatening activity. For instance, if a vessel is found operating outside of its normal shipping route or its movements suggest surveillance or espionage, the system can trigger an alert, allowing security forces to investigate immediately.
Maritime security information-sharing platforms are crucial in mitigating the risks posed to subsea cables. Sys-
In addition to real-time monitoring, AI-based fencing technology can create virtual ‘geo-fences’ around the most vulnerable areas. If any unauthorized vessel crosses these restricted zones, the system sends an alert to the authorities, acting as a proactive approach that enables early detection of potential threats before they can cause damage. By integrating machine learning, these systems can even learn from preceding incidents, improving their ability to predict and classify future risks, such as espionage, sabotage, or even natural disasters.
On the other hand, one of the most interesting advances
in submarine cable technology is the development of so-called SMART (Sensor Monitoring And Reliable Telecommunications) Cables. These cables do more than just transmit data; they are also equipped with sensors that actively monitor the environment around them. This type of equipment can detect things like seismic activity, tsunamis, ocean bottom pressure, ship movements or even temperature changes, which allows them to send data in real time to the authorities on land. This technology acts as an early warning system, alerting authorities to potential threats, whether it’s an impending natural disaster or a suspicious ship or other (submersible) equipment in the vicinity that could pose a risk of sabotage.
Ultimately, the protection of subsea cables is a challenge that demands a concerted global effort. No single nation can effectively safeguard its own waters in isolation, as the scope and importance of this infrastructure extend far beyond national borders.
Currently, the world’s first SMART cable system, called TAMTAM, is being deployed between Vanuatu and New Caledonia in the Pacific Ocean. This region is particularly vulnerable to tectonic activity, making it an ideal location for the deployment of these advanced cables. Additionally, projects are also underway in regions such as Portugal, where a SMART cable is set to connect the mainland to the Azores and Madeira.
By integrating this SMART Cable technology with existing Maritime Security Platforms, the global security network becomes much more powerful. These platforms already track the movements of vessels using AIS, satellite and RADAR tools, but combining this layered information with the real-time data from smart cables provides a much clearer picture of what is happening underwater, on the surface and possibly in the airspace.
– provide an essential foundation for the protection of subsea infrastructure, they are no longer sufficient in addressing the complex and evolving threats of the modern era, particularly those related to cybersecurity and physical sabotage.
In today’s world, where cyber and physical threats are more sophisticated, modern agreements and updated strategies are urgently required to tackle the specific challenges posed by the 21st century. This is especially crucial as more cables are being laid in geopolitically strategic areas, such as the Arctic and the South China Sea, where tensions and vulnerabilities are higher. Therefore, ensuring the continued security of the global digital network will depend on robust international cooperation, coordinated efforts among governments, and comprehensive approaches that blend advanced technology with effective policy frameworks. The security of these digital lifelines is not just a matter of national interest but a collective global responsibility. STF

Through a combination of cybersecurity protections, real-time data sharing, and AI-powered threat detection, maritime security platforms offer a promising solution to the escalating risks facing subsea cables. These measures can help prevent both accidental and malicious damage, ensuring that the global network remains secure.
Ultimately, the protection of subsea cables is a challenge that demands a concerted global effort. No single nation can effectively safeguard its own waters in isolation, as the scope and importance of this infrastructure extend far beyond national borders. To ensure the security of these vital connections, countries must actively collaborate and coordinate across regions. While frameworks like the United Nations Convention on the Law of the Sea (UNCLOS)[3] – adopted in 1982

FEATURE THE ‘WET WAR’ Could Submarine Cable Security Concerns Threaten Global Stability?
BY JOHN TIBBLES
INTRODUCTION
Has there ever been a period when subsea cables a have been so often in the news? Not only have they been in the media almost daily, but for mostly the wrong reasons. They seem to have almost become either weaponised or legitimate targets rather than bridging oceans and societies to bring people together for peaceful reason. This was an idea postulated by the telegraph pioneers 150 odd years ago with the completion of first Trans-Atlantic cable.
How have we come to this from a seemingly tranquil subsea environment that allowed telecom companies and more recently internet content providers to connect the world to an unprecedented degree? We have arrived at this worrying situation where our once niche and invisible industry is no longer threatened by geopolitical tensions but is the cause of them.
The answer of course is politics!
SOME HISTORY
In the three decades since the Berlin Wall fell and the Cold War ended, telecom carriers, content providers and entrepreneurs built cable networks for their own services but also as business opportunities. Politics in that era that
meant fishermen’s rights, local planning/zoning authorities and some regulatory issues. Often annoying, but benign compared with what we face today
That isn’t to say that governments were not involved with cables via various security and or military bodies but there was not the focus that there is today. Ten years ago, a dragged anchor could cut a cable, and it didn’t make the news media, now its prelude to WW3.
Subsea cables have existed for 150 years and have been targeted occasionally since then. In the late 1950s when the first TAT cables were built, they were to serve both civil and military needs.
These early systems were largely built by and used by the USA’s, AT&T, who were the world’s largest international telephony carrier and used their own technology and resources to build the cables. They also used their domination of the voice market to their advantage, but they didn’t control the content of the calls. There were other parties, UK, France, Japan etc. who also had large volumes of traffic and the capability to construct, install and maintain such systems. This carried on well into the optical fibre age as the likes of TAT8 and PTAT lead the industry into the new era mostly dominated by consortium systems but also some
private competitors. There was still government involvement since outside the USA it was the norm for telecom carriers to be state owned enterprises. Even after deregulation and privatisation there was still the opportunity for political involvement on issues such as protection of suppliers and use of the cable ship fleets. Deregulation also promoted ‘open access, allowing for the first time telecom operators to access cables at both ends to provide the global networks of the 80s and 90s.
THE RISE OF THE INTERNET
Google and the social networks with very high-volume data transfer speeds completely changed the use of cable from telecom operators to global content providers who worked together to build their own systems higher capacity with more intriguing names than TPC or TAT.
Unlike the ex-monopiles they didn’t have the long-term relationships with military and security services that the major global carriers had. However, the content providers rapidly began to rule the waves to the point where we arrive at today with the announcements of two real mega entirely global systems developed for Google and Meta. Truly global these will provide the capacity for the next big thing - AI. Both are major US corporations and inevitably closely connected to political and governmental entities enabling US control of the Internet and subsea network to reach a new level.
DIGITAL POLITICS
The new dominant parties not only control how data gets from A to B, but they also control much of the content that is carried and much of what they don’t control other US monoliths like AWS and Microsoft do.
Because of this unprecedented level of control and its critical importance to global trade, media and social interaction’ government awareness recognised how the world economy depends on the internet and its building blocks. Data centres and terrestrial wireless networks are essential elements, but they are located in individual countries and thus comply with national legislation. It is the subsea cables that link the world together, out of sight and outside the jurisdiction of any one government since International Waters are just that International and outside of any one countries control.
There is of course UNCLOS, the United Nations Law of the Sea but it is very widely encompassing and does not provide detailed provisions on subsea cables that reflects their importance today.
It is only in recent years that digital technology has been
the focus of concern in terms of national security. It started with concerns about China’s Huawei mobile/cell phone infrastructure and has migrated from there to subsea.
STATE INTERVENTION ONCE AGAIN
Early cables were owned by state owned monopolies and thus effectively controlled by a small number of maritime states. As 2025 dawns subsea cables are front and centre in media coverage and in the security concerns of many countries. Consequently, in September the UN developed a pact known as the Global Digital Compact (GDC) aimed at promoting the need for legislation and action to enhance the security of digital infrastructure; especially subsea cable which are almost entirely in international waters. It also drew attention to the existence of choke points on the network and the need for strategic diversity, transparency in the manufacture of subsea plant and scrutiny of the limited number of subsea cable equipment providers.
The United states Bureau of Cyberspace and Digital policy had clearly expressed goals resulting in a US Department of Homeland Security (DHS) policy paper which states:-
‘DHS POLICY PRIORITIES FOR SUBSEA CABLES’
• Ensure continued U.S. leadership in the subsea cable industry.
• Promote secure and resilient subsea cable networks and supply chains and counter foreign adversary threats’ (https://www.dhs.gov/news/2024/12/18/dhs-leadershipsupport-subsea-cable-security-resilience)
US Homeland security have already intervened in helping fund cable projects in the Pacific and Indian Oceans to ensure they were built by Subcom whose management apparently have connections to the incoming US administration. DHS have also made it clear that systems where there is a strong element of control by states they are not comfortable with, i.e. China, will not get landing rights in the USA. Such a policy of course could prevent any new US-China system and thus impair communications between the world’s biggest economies.
Another type of state intervention is the French Governments purchase of ASN, the world’s leading supplier of subsea cable systems. Subcom, are committed to providing the massive Google network which will stretch their production capability, but ASN may secure much of the Meta network contracts or will there be a transatlantic US vs EU/UK trade dispute over submarine cable provision? In different area of subsea, operations, the Government of Italy is aiming to ensure that TI-Sparkle with its extensive
FEATURE
subsea network especially in the Mediterranean will remain in Italian ownership
Such actions will also impact third parties especially as the US requirements for surveillance and transparency on new systems will increase system production costs and limit the opportunities for multi-party cost sharing because some locations on a major route may not be deemed acceptable to the USA. In that case not only are they excluded but the price increases for others in the project who must bear the costs of losing one or more landings. Sustainability in manufacturing and installation may be deferred to save costs and along with the environment this does not seem to be a priority of the incoming US administration.
So called private systems which already have difficulty attracting funding because of the perceived risks to successful deployment will face even greater challenges because of these requirements. Something already demonstrated in the Pacific area.
A SECOND DIGITAL DIVIDE
The phrase digital divide describes the differences in accessibility to digital service for commerce and leisure between what is often called the developed and developing world. It is an economic term.
The US and the 36 countries signed the so-called UN New York protocols but that means 100 or so countries didn’t. That includes places with some of the world’s largest populations like India, China, Indonesia and Africa. Consequently, much of the world gets dragged in to the long-standing US China technology disputes which may well get more intense with the change of Government in the United States and already foreshadowed by the DHS proposals.
All these developments lead to situations where it will become harder and harder to build networks that serve the needs of all the populations on potential routes resulting in a second ‘political ‘digital divide. The massive increase in traffic because of the wider use of AI and thus the internet in general means more and more people risk become isolated from others because they are served by the ‘wrong’ network. The increase in capacity that AI already requires today may not be there tomorrow due to this political separation into two global subsea network groupings and thus two internets. This is something I discussed in previous articles for STF, one lead by the USA and the other by China. ‘Billions of Dollars versus Billions of People’ ???
CONCLUSIONS
It is reasonable for any government to protect its territory and economic foundations from serious impairment.
but much of the digital infrastructure now the focus of such concern is not wholly within one country’s territory or territory of its allies. International subsea cables are by their nature terminated in different countries that may have diverging political and economic policies. Will there be another US China system under these rules? What will happen to regional systems in the South China sea and western India Ocean where smaller, non-aligned states may have difficulty in increasing capacity to the two major regional states China and India if they also want US connectivity.
Of course, the USA is not alone in having these concerns and wanting to protect is geopolitical and economic interests. Other world power nations have the same issues and will surely react , for example could a second BRICS concept develop as an alternative to having to build under Homeland Security/NY Protocols. That grouping alone has close to 4 billion people around the world and rapidly growing their appetite for online commerce and social networking. In Europe, notwithstanding their support for the NY Protocols they must preserve the capability to build subsea systems by supporting ASN and secondly acting as a moderator or mediator.
Finally, as indicated in the title will the world face a new phenomenon a ‘Wet War’ a lack of interconnection between two internets where both leading proponents seek to control not just connectivity but content and which escalates beyond the seabed. Impairment of global communication because of over hyped concerns about subsea networks would be catastrophic! Perhaps we will be saved from that dangerous development by a doctrine taken from the Cold War era ‘Mutually Assured Disruption’!
I would like to thank Elina Noor Senior Fellow Asia Program at the Carnegie Endowment for International Peace for her excellent article on Subsea Network Resilience in S E Asia where she addresses some of these issues in a more scholarly way. STF

FROM FOLLOWER TO LEADER:
How The Middle East Is Shaping The Future Of Global Connectivity
BY BRENDAN PRESS

In the telecommunications industry, for a period, it was believed that the Middle East was playing a game of catch-up with other international markets. However, it’s fair to say that the region is now a key player in the global connectivity landscape.
A decade of dramatic economic growth has placed incredible demand on digital services, with digitally empowered citizens expecting high speed and quality connectivity. In response, cable providers have invested in their networks and diversified their routes through the region. Some of the world’s largest hyperscalers are even laying down their own infrastructure to future-proof operations. Content enablers situated in and around these regions are investing in new points of presence (PoP) to open opportunities to the rest of the world too.
The Middle East is and will continue to be a unique and exciting place to do business. For the players who want to get a piece of the pie, there are important points of difference to understand and implement. From evolving business models to supply chains, ultimately, it’s prioritising partnerships and collaboration that will be the winning formula.
A UNIQUE CROSSROADS
Geographically, the Middle East occupies a strategic position between East and West, making it an essential hub for global data flows. This unique advantage has long attracted investments in submarine cables and terrestrial networks to bolster international connectivity. Today, countries such as the UAE and Qatar are not just transit hubs but innovation epicenters. With high-speed links spanning
FEATURE

Asia, Africa, and Europe, the region is pivotal in ensuring uninterrupted global internet traffic.
Additionally, the Middle East’s abundant sunlight is one of the region’s most valuable natural resources, offering a distinct advantage for data centers. By harnessing solar power, data centers can develop advanced cooling systems capable of handling the extreme temperatures that define the Gulf climate. This integration of solar energy into connectivity infrastructure reflects the Middle East’s forward-thinking approach, leveraging its natural assets. In addition to its solar-powered advantage, the Middle East also boasts favorable conditions for business growth. The region’s availability of vast expanses of land provides ample space for constructing data centers and other critical infrastructure. Combined with a regulatory environment
that is increasingly business-friendly, the Middle East is positioned as an attractive destination for global investments.
INVESTMENTS IN DIGITAL INFRASTRUCTURE
The Middle East’s transformation into a global connectivity hub has been driven by its ability to rapidly scale digital infrastructure to meet surging demand. Over the past decade, telecom providers have embraced innovative technologies and embarked on ambitious network expansions to keep pace with the region’s growing digital economy. These investments have ensured the region is equipped to support both local and international digital ecosystems.
Take Qatar, for example. As part of its National Vision 2030, the country is strategically investing in digital infrastructure, positioning the telecom industry as a critical enabler of a dynamic, innovation-led economy. By recognizing the importance of robust infrastructure, Qatar’s Vision aims to create environments where businesses can process vast amounts of data, develop cutting-edge digital products, and expand their services regionally.
Across the Middle East, similar strategic goals are being pursued. This drive for digital transformation and the integration of emerging technologies such as artificial intelligence (AI), cloud computing, and the Internet of Things (IoT) spans across key sectors - from finance to retail and public services. These efforts are reinforcing the region’s role as a key junction for the global internet backbone, with diverse and resilient routes connecting East and West.
NO LONGER PLAYING CATCH UP
The Middle East’s transformation from a follower to a leader in the connectivity landscape can largely be attributed to the role of hyperscalers, cable networks, and overthe-top (OTT) service providers. These hyperscalers have recognized the region’s immense potential and are making substantial investments to build out their own infrastructure. By establishing data centers and PoPs across multiple nations, they reduce latency and create an environment conducive to digital innovation.
For example, the expansion of data centers across the Middle East by hyperscalers like Amazon Web Services, Microsoft Azure, and Google Cloud is driving the adoption of cloud computing. These providers offer scalable services that allow businesses in the region to manage and process large datasets with reduced latency. For instance, Saudi Arabia’s Vision 2030 includes developing cloud computing infrastructure to support digital transformation across sectors, enabling more efficient government services, financial institutions, and businesses.

The demand for advanced technologies like IoT and AI is also driving demand across the region. For example, in finance, AI is supporting predictive analytics, risk management, and fraud detection. In retail, it enhances personalized customer experiences through recommendation engines. Healthcare also benefits from AI with predictive analytics for patient outcomes and personalized treatment plans. What’s more, Governments are leveraging AI for efficiency in the public sector, using smart city initiatives and automated administrative processes to improve urban living.
The integration of IoT is transforming industries such as smart transportation, utilities, and manufacturing. In the Gulf region, cities like Dubai are becoming smart cities equipped with IoT technologies to manage infrastructure - from traffic lights and parking systems to energy use and water management. These advancements are innovating the industrial and logistics sectors, creating new benchmarks for efficiency and automation in the global market.
These advancements underscore the critical need for reliable connectivity with low latency, which is essential for supporting not only mission-critical industries, but the region’s ambitions to remain at the forefront of global connectivity.
STRATEGIES FOR SUCCESS
To capitalize on the growth opportunities presented by the Middle East, businesses should consider several key fac tors. Understanding and navigating the regulatory landscape is crucial; business-friendly policies - such as incentives for
economic diversification, tax benefits, and grants for sustainable energy projects - can significantly enhance a company’s competitive advantage. Businesses that leverage these incentives can position themselves well within the Middle Eastern market and take advantage of its growing digital economy.
Moreover, the region’s challenging climate - particularly the high temperatures common in the Gulf - necessitates specific operational strategies for data centers. Innovative solutions, such as solar power can help address these challenges effectively, ensuring operational efficiency in this unique environment.
Finally, forming strong partnerships with local stakeholders - including government bodies, technology providers, and renewable energy firms - can provide critical resources and support. These collaborations enable businesses to access local market insights, expertise, and supportive policies necessary for long-term sustainability in the region. With the right partnerships, businesses can effectively navigate the Middle East’s dynamic landscape, taking advantage of its growth and positioning themselves to thrive within the global connectivity framework.

FEATURE THE IMPACT OF AI ON SUBMARINE NETWORKS
BY BRIAN

Although associated with a great deal of hype, Artificial Intelligence (AI) is real and will undoubtedly have an impact on our business and personal lives, although to what extent remains to be seen in the coming years. Before it can have a significant impact our lives, it will first impact networks, including submarine networks. There are two ways to look at the impact of AI on submarine networks: “infrastructure for AI” and “AI for infrastructure.” Infrastructure for AI refers to the impact on storage, compute, and connect (network) assets that bring AI to life, albeit a digital one. AI for infrastructure refers to using AI on infrastructure itself — such as minimizing energy consumption or improving network traffic patterns for an optimal return on existing network assets over time.
INFRASTRUCTURE FOR AI
Large Language Models (LLMs) leverage Deep Learning (DL) using artificial neural networks, which “mimic” biological concepts related to how the human brain works. For an LLM to be successfully trained, massive amounts of valid training data is required. Unless this data is already in the cloud data center where the AI infrastructure is hosted, it must be moved into the cloud, say from a large en-
terprise. Given LLMs require massive amounts of training data, especially for AI related to images and videos, edge networks can become quickly overwhelmed. To address this bottleneck, substantial upgrades are required for AI to be successfully rolled out at scale, with Figure 1 showing the estimated time it takes to move different dataset sizes into a cloud AI data center for LLM training.
From a submarine network perspective, this data may move from one continent to another over several thousands of kilometers, potentially requiring substantial capacity upgrades to Data Center Interconnection (DCI) undersea corridors. However, national regulations dictating where and how data is stored, moved, and used will have a yet-tobe-determined impact on how much submarine network bandwidth will be required for LLM training purposes. Given most LLM training is centralized today as AI infrastructure is still being rolled out, the LLM impact on submarine networks will take time – but make no mistake, AI traffic will impact submarine network bandwidth demand,

LAVALLÉE

as evidenced by the massive amount of ongoing cable and capacity upgrades by hyperscalers for future AI purposes.
INTRA DATA CENTER NETWORKS
AI was borne in the same data centers hosting traditional non-AI cloud services that we use daily in our business and personal lives. However, AI storage, compute, and network infrastructure requirements quickly became too complex and demanding for traditional cloud infrastructure for use cases like LLM training, the underlying technology of Generative AI (GenAI) applications. Traditional cloud infrastructure success is driven by being cost-effective, flexible, and scalable, which are also essential attributes for AI infrastructure. However, a new and more extensive range of network performance requirements are needed for AI, such as rapid dynamic resource scaling, higher bandwidth, isolation to eliminate resource contention, and lower latency.

AI applications, such as LLM training leveraging DL and artificial neural networks, involve moving massive amounts of data within a data center over short, high-bandwidth, low-latency networks operating at 400Gb/s and 800Gb/s to 1.6Tb/s and even higher in the future. Just like customized AI-specific processors like Central Processing Units (CPUs) and Graphics Processing Units (GPUs) are being developed, network technology innovation is also required to fully optimize AI infrastructure such as new optical transceivers, Optical Circuit Switches (OCS), co-packaged modules, custom Network Processing Units (NPUs), standards-based UEC and UALink-based networking platforms, and a myriad of other new and exciting networking technologies.
Although network technology advancements will help address AI performance challenges, the massive amounts of required space and energy consumption associated with AI will lead to many more data centers being constructed and interconnected, overland and undersea, to unite land, sea, and cloud networks. The distances within and between data centers will require very different network technology and network solutions.
CAMPUS NETWORKS
A single modern GPU, the foundational element of AI compute clusters, can consume as much as 1,000 watts,
so when tens to hundreds of thousands (and more) are interconnected for purposes like LLM training, associated energy consumption becomes a monumental challenge for single data center operators. New AI infrastructure will rapidly consume energy and space within existing cloud data centers. This is leading to new data centers being constructed in a “campus” where data centers are separated typically by 10 kilometers or less to minimize latency for improved AI application performance and LLM training convergence. Campuses will need to be located near available energy that is reliable, sustainable, and cost-effective. Campus data centers will be connected to each other and to distant data centers using optics optimized for specific cost, power, bandwidth, latency, and distances.
DATA CENTER INTERCONNECTION (DCI) NETWORKS
As AI infrastructure is hosted in new and existing data centers, interconnections similar to those currently used for traditional cloud services will be required. This will be achieved using similar optical transport solutions, albeit at higher rates, such as modern Submarine Line Terminal Equipment (SLTE) modems operating at 1Tb/s or higher over transoceanic distances. How much new traffic are we talking about? According to recent analysis from research firm Omdia, monthly AI-enriched network traffic is forecasted to grow at approximately 120% (CAGR) from 2023 to 2030, as shown in Figure 2, meaning a lot of additional traffic for global networks to carry in the future, some of which will be carried over submarine cables with the exact amount to be determined, as it’s still early days for precise AI traffic forecasting and segmentation, but it looks promising for cable operators too.
For enterprises, AI is driving the need to migrate data and applications to the cloud due to economics, in-house gaps in AI expertise, as well as challenging power and space limitations. As cloud providers offer AI-as-a-Service and/
Figure 2: Net new monthly AI-enriched network traffic growth forecast from 2023 – 2030 (source: Omdia)
FEATURE
or GPU-as-a-Service, performing LLM training in the cloud will require enterprises to move huge amounts of training data between their premises into the cloud across different instances, including submarine networks in some cases. This will drive the need for more dynamic and higher speed bandwidth interconnections, requiring more cloud exchange infrastructure, which represents a new telco revenue-generating opportunity.
DISTRIBUTED LLM TRAINING
In some cases, the required data to train an LLM may not be allowed to leave a country due to local data privacy laws. To overcome this requirement, a centralized LLM in training can be pushed to data centers in different countries over submarine cables, trained using in-country data, and the updated models sent back to a centralized data center for consolidation. Once updated, the model is sent back to regional data centers for further training using local data that remains in country. Eventually, the LLM model flowing back and forth converges to a “trained state” without training data ever leaving regional data centers thereby respecting local rules and regulations. The fully trained LLM is then pushed out to regional data centers in different countries over submarine networks for inferencing, using the LLM with real-world data. The amount of traffic carried between data centers over submarine cables in such a training scenario will also be less than moving LLM training datasets into a centralized data center.
by humans or machines, allows for faster data processing for near real-time AI inferencing to be achieved, meaning more edge data centers interconnected and more AI models flowing over terrestrial and submarine networks of varying distances depending on where the LLM is trained and then used for inferencing.
BALANCING ELECTRICAL POWER CONSUMPTION AND SUSTAINABILITY

AI is being deployed at an increasingly rapid pace, creating new opportunities and challenges. A serious challenge to be addressed is that AI infrastructure is notoriously power-hungry during the LLM training phase, which consumes so much electricity that new and existing AI data center locations are highly dependent upon the availability of reliable, secure, and cost-effective energy generation and distribution. This means not all countries will be able to host AI training infrastructure, over and above geopolitical concerns, so training data for such countries will have no choice but to flow over submarine networks to distant AI infrastructure. This challenge is exacerbated as LLMs become more complex, requiring constantly increasing amounts of compute, storage, and network capabilities.
OPTIMIZED AI PERFORMANCE AT THE NETWORK EDGE
Once an LLM is trained, it’s “optimized and pruned” to provide an acceptable inferencing (i.e., using AI in the real-world) accuracy within a much smaller infrastructure footprint in terms of compute, storage, and energy usage. These optimized AI models are pushed out to the edge to reduce the strain on core data centers hosting LLM training, reduce latency, and abide by regulations related to data privacy concerns by hosting data locally. Placing AI storage and compute assets in geographically distributed data centers closer to where AI is created and consumed, whether
Although AI infrastructure compute and storage assets consume far more electrical energy than the networks that interconnect them, network bandwidth growth cannot scale linearly with associated power consumption – this is not sustainable or cost-effective. This means network technology must also consistently reduce electrical power (and space) per bit to “do its part” in an industry so critical to enabling AI. Figure 3 illustrates how Ciena’s relentless Submarine Line Terminal Equipment (SLTE) modem technology evolution continually improves the achievable spectral efficiency while also reducing the required power per and space per bit from an AI network viewpoint.
AI FOR INFRASTRUCTURE
Although networks, overland and undersea, will ultimately dictate the success of AI infrastructure rollouts and associated services, the benefits of AI can be used on
Figure 3: Ciena WaveLogicTM modem innovation constantly improves power and space savings per bit

the networks as well to improve their design, deployment, and ongoing operations. AI can aid in the design of the most efficient network designs to ensure optimal energy consumption once the end-to-end network, including the submarine cable and terrestrial backhaul segments, is up and running. AI can use gathered real-time telemetry data from highly instrumented networks to generate actionable insights such as recommending preventive maintenance to addressing impending outages before they occur, optimizing traffic routes to better utilize existing assets to defer or eliminate expensive capacity upgrades, and providing faster fault resolution by examining and analyzing real-time alarms and performance data.
AI chatbots can also be used, allowing network operators to “talk to their network” to rapidly create new network services, perform “what if” scenarios to decide how and when to perform capacity upgrades via interactive network planning, and receive instant guidance on tasks rather than having to wade through oceans of manuals.
AI can be used to improve professional services that are always critical to the successful deployment and operation of any submarine network, from the lifecycle stages of cradle to grave, and everything in between. AI can aid in determining how, when, and where to perform network capacity upgrades, how to roll over traffic to new network assets, and effectively retire existing submarine cable networks. AI complements human service knowledge and expertise to do what’s already being performed — albeit faster and more efficiently with fewer manual task errors.
AI DATA IS ONLY VALUABLE IF IT CAN MOVE
According to TeleGeography, as shown in Figure 4, content providers represent most international bandwidth growth in all regions worldwide. As they continue to invest eye-watering amounts of money into AI data centers, the amount of associated traffic flowing over terrestrial and submarine networks will grow unabated. AI investments are currently taking place inside data centers to develop LLM training clusters (storage, compute, networks) and is where most network traffic growth is today. However, as AI
inferencing (using trained AI LLMs on real-world data) is rolled out to the network edge coupled with training data and models moved between data centers, traffic will certainly grow across long distance terrestrial and submarine networks, although it’s still early days to quantify how much new traffic this will be and where, but overall, it will be significant in the long term.
THE SUCCESS OF AI DEPENDS ON NETWORKS
Hype aside, AI will provide new benefits across different industries that will positively affect both our business and personal lives over time. However, the rapid and widespread adoption of AI is heavily dependent on many factors like ongoing capital investments, new data centers, energy availability, geopolitics, and more. This is no different from other technology inflection points, like steam engines, electricity, and the internet. As AI challenges are worked out over time, its success and widespread availability will continue unabated with networks ultimately determining its success because AI is only valuable if data moves, and this is the critical role of networks, overland and undersea. By uniting terrestrial, submarine, and cloud networks, the success of AI will continue unabated. STF

BUILDING
THE SUBTEL FORUM
MAGAZINE ARCHIVE
A Journey of Innovation, Technology, and Industry Empowerment
BY KIERAN CLARK
The launch of the SubTel Forum Magazine Archive marks a transformative moment for SubTel Forum. For the first time in over 20 years of publication, the magazine’s entire history—over 140 issues spanning two decades—has been digitally unified and made accessible to professionals, researchers, and enthusiasts in the submarine telecom industry. The Archive isn’t just a collection of PDFs; it’s a thoughtfully curated resource that brings the history, trends, and innovations of the submarine cable industry to everyone’s fingertips.
This achievement required an innovative combination of technology, expertise, and collaboration, from leveraging AI for data extraction to building a custom WordPress plugin tailored to meet the Archive’s unique needs. Here’s the story of how it came together.
EXTRACTING AND ORGANIZING TWO DECADES OF DATA
The first and most significant challenge was making sense of
over 140 legacy PDFs. The older issues, published as far back as 2001, lacked the structured metadata necessary for uploading and managing them efficiently on platforms like Issuu. Details like publication dates, themes, and issue titles were often inconsistently formatted or buried within the documents themselves.
Faced with this daunting task, the SubTel Forum team turned to AI, leveraging its growing expertise in automation and machine learning. Instead of manually sifting through each PDF, the team developed a Python-based AI tool capable of scanning, identifying, and extracting key metadata. The tool could locate and standardize essential details, creating structured data files for each issue. This innovation not only saved countless hours but also ensured greater accuracy than a manual process could have achieved.
LEVERAGING ISSUU FOR SEAMLESS INTEGRATION
With the metadata in hand, the next step was deciding how


to host and present the Archive. The team chose Issuu for its robust capabilities, including responsive viewing, interactive features, and ease of access for users across devices. However, working with Issuu wasn’t as simple as uploading the PDFs.
The team had to dive into the Issuu API to automate the upload process and ensure every issue was paired with its correct metadata. By integrating API calls into the workflow, the team could upload each issue with its title, description, and publication date already populated, ensuring a professional and seamless presentation.
Even with API integration, there were challenges. Older issues required additional adjustments to align with modern platform requirements, while newly published issues needed to sync with the Archive’s structure. Weekly updates were automated, ensuring the Archive remains current without requiring significant manual intervention.
CUSTOM WORDPRESS PLUGIN: A TAILORED SOLUTION
As the Archive began to take shape, another critical decision arose: how to integrate it into the SubTel Forum website. Existing solutions were considered, but they often came with significant drawbacks. Off-the-shelf plugins or third-party tools lacked the flexibility needed to handle the Archive’s unique requirements. Many would have required starting from scratch, re-uploading all the content and metadata to fit predefined structures.
Instead, the team opted for a custom-built WordPress plugin. This approach allowed for complete control over the Archive’s design, functionality, and user experience. The plugin connects directly to the Issuu API, fetching the latest data weekly to keep the Archive current. It also organizes the issues by year, displays them in an intuitive grid layout, and includes a sticky sidebar navigation to help users jump to specific years quickly.
The decision to build a custom solution wasn’t just about functionality—it was about future-proofing the Archive. With the flexibility of custom code, the team can continue to expand the Archive’s capabilities, such as integrating it with other tools and resources.
The result of this work is a digital library that is both accessible and visually engaging. The Archive groups issues by year, displays them in a clean grid layout, and allows users to explore each issue via clickable cover images. Each issue is accompanied by its title, theme, and publication month, giving users immediate context about its content.
KEY FEATURES INCLUDE:
• Dynamic Updates: The Archive syncs weekly with Issuu, ensuring new issues are available as soon as they’re published.
• Interactive Layout: Users can browse issues organized by
year and quickly navigate using a sticky sidebar.
• Comprehensive Coverage: Every issue from 2001 onward is included, making this the most complete resource on the submarine telecom industry’s history.
For industry professionals, the Archive is more than just a convenience. It’s a resource for historical research, a tool for identifying trends, and a gateway to the insights that have defined two decades of innovation.
A GLIMPSE INTO THE FUTURE: THE AUTHOR’S INDEX
The Archive’s launch is just the beginning of a broader vision. While it provides a centralized platform for accessing SubTel Forum issues, the team is already working on the next phase: the Author’s Index. This project will transform the Archive into a fully searchable database of all articles and authors featured in SubTel Forum
Before the Archive, finding a specific article or author was an arduous process, requiring users to manually search through individual PDFs. The Author’s Index will change that by linking directly to articles in the Archive, enabling users to search by keyword, topic, or contributor.
Building the Author’s Index requires careful preparation. The Archive was a critical first step, ensuring all issues were digitally organized and easily accessible. The next challenge lies in indexing each article, a task that will rely on the same AI expertise used to build the Archive.
The development of the SubTel Forum Magazine Archive is a testament to the SubTel Forum team’s commitment to innovation. From leveraging AI to solve data challenges to building custom tools that align with the industry’s needs, every step of this project reflects a forward-thinking approach.
This Archive isn’t just a celebration of SubTel Forum publication history. It represents a commitment to making that history accessible to the global community while laying the groundwork for future innovation.
For the submarine cable industry, the Archive represents a new era of accessibility and connectivity. Explore the Archive today at subtelforum.com/magazine-archive. Whether you’re a seasoned professional or a newcomer to the field, this resource is designed to provide value, insight, and inspiration for years to come.
Beyond its usefulness to the industry, the Archive was a valuable learning experience for the SubTel Forum team. It required mastering new tools, working across multiple platforms, and solving challenges that spanned data management, web development, and user experience design.

BACK REFLECTION
PRACTICAL INTRODUCTION TO THE EARLY DAYS OF CABLE FAULT FINDING
BY PHILIP PILGRIM
Happy New Year and best wishes for a prosperous 2025 ! The first three Back Reflections of 2025 will be dedicated to subsea cable fault finding in the very early days of submarine telecommunications. This is a very interesting and important topic, though somewhat technical. In fact, many of today’s principals in applied electronic theory were discovered / developed in these early years. For example, the “common mode rejection” principal, “balanced circuits”, and “ isolated ground” that we find in microphone circuits, hospital “safe” power, ground fault interrupts, and operational amplifier circuits go back to the 1865 & 1866 Atlantic cables. The next time you see a performer hold a microphone [Fig. 1], you will have to imagine two conductive wires in that microphone’s cable being the two Atlantic Cables!

If you currently operate, or maintain, contemporary submarine cables, it is worth your time to understand the fundamental principles for testing and fault finding. Electrical fault finding has not changed much over the past 175 years and the methods are still used today. The copper, or aluminum, cores of today’s fibre optic cables are nearly identical to the copper cores of telegraph cables. The only minor difference is the semiconducting power circuits found in repeaters and active wet plant devices (e.g., Wavelength Selective Switch).

Down-time, due to faults, was as costly to cable owners of old as it is these days. Using standard fault finding techniques, and making careful measurements, one can quickly locate the fault and reduce repair time and traffic outage time. At over $100,000/day for repair ship costs, and often even more for traffic revenue lost, it is surprising that little attention is given to this very important skill. Telegraphic communications was man’s first large scale exploitation of electricity. In the 1830’s and 1840’s, we saw the invention & rapid growth of terrestrial telegraph systems (predominantly buried gutta percha networks in Europe
Fig. 1 Balanced Microphone Circuit

and pole lines in North America). At that time, many scientists were involved directly, or indirectly, with telegraphy. These great minds were busy with the mundane challenges of improving the crude systems that used switches, wires, insulators, and batteries; but from their efforts, electromagnetic theory, signaling theories, coding theories, encryption theories, electronic component theories, manufacturing techniques, scientific standards & units, manufacturing chemistry, metallurgy, navigation, time standards, processes & quality, and even very bad poetry arose. The telegraph was a catalyst for discovery and invention whose returns for mankind far exceeded even those of all space programs of the 1960’s.
EARLY UNITS:
Although Alessandro Volta (Volt) had passed in 1827, and André-Marie Ampère (Amp) in 1836, Georg Simon Ohm (Ohm) was still alive to witness the early submarine telegraph cables.
In the early 1850’s, there were no SI units. There was no “volt”, there was no “amp”, and there was no “ohm”. However, we did have an understanding of Ohm’s 1827


Theory I = V / R.
Voltage references for the early cables were simply the number of batteries connected in series. Although Alessandro Volta invented the battery in 1800, a practical battery was not developed until 1836 by the British scientist John Frederic Daniell.
Current references for the early cables were simply “compass” deflections (in degrees) using a standard tool called a Galvanometer. Hans Christian Ørsted invented the instrument in 1820, and its improvements continued for many decades to increase its sensitivity. Although it was initially a test instrument for the early submarine cables, a highly sensitive version became the “receiver” for the Atlantic Cables. Resistance references for the early cables did not exist for the first few years. Resistive coils (spools) soon became references. However, a unit or measure was

first used in 1860. It was the Siemens Unit (S.U.) proposed by Werner von Siemens, who was heavily involved in subsea cable manufacturing. The S.U. was based on the resistance of a column of mercury at a specific temperature.
[Fig. 2] is an 1874 schematic for a network with resistance in S.U. and voltage is # of cells
EARLY TEST INSTRUMENTS:
In the 1850’s, the test instruments used in submarine cable construction, laying, and maintaining were: the Daniell Cell (battery), Resistance Coils, the Galvanometer, and the Wheatstone Bridge.
DANIELL CELL
This battery was invented in 1836 and was one of the first practical batteries. It was first used in subsea demolition to clear the sunken ship Royal George in 1839. A submarine umbilical connected the explosives to the battery.
The Daniell cell [Fig. 3] consisted of a copper anode (+) and a zinc cathode (-). The copper container was filled with a copper sulfate solution and a porous pot (earthenware) held the sulfuric acid and “zinc”. These batteries required a great deal of attention to function. Refreshing the acid and replacing the plates were typical chores. Usually, a telegraph station had workers dedicated to maintaining the batteries. The batteries could be wired in series [Fig. 4] to increase the voltage applied to the cable when testing.
RESISTIVE COILS
These were simply spools of wire that would emulate distances of submarine cable. The units used were in nautical miles of cable [Fig. 5]. As there were no units of resistance until



the Siemens Unit “S.U.” in 1860, these resistive coils were bespoke. There were also rheostats (variable resistors) in use [Fig. 6]. One variant had a crank and dial [Fig. 7] which showed the wire’s length in nautical miles of cable.
GALVANOMETER
These early devices for measuring current consisted of a compass and a coil of wire. The compass would deflect relative to the current through the coil. The instrument shown below [Fig. 8] is an Astatic Galvanometer. It has two compass needles (one in reverse) to neutralize the Earth’s magnetic field. The current to be measured passes through a coil that only acts on one of the needles.

The deflection of the needle was not directly proportionate to the current, so early measurements of submarine cables did not easily translate to I = V / R. For example, in the cable factory,
Fig. 7 Early Rheostat Variant
Fig. 5 Resistive Coil Set
Fig. 6 Early Rheostat
Fig. 8 Astatic Galvanometer
if 60 batteries were applied to the full cable, and the instrument deflected 10°, the same 60 batteries applied to half the cable may cause a deflection of 25°. If the deflection followed true current, we would assume 20° deflection at twice the current. For this reason, if you wanted to know the current (deflection) to shorts (faults) along the cable, you would have to make baseline measurements in the factory as the cable was constructed. This baseline work was done on the four 1853 Dutch-UK cables at steps of 10 nautical miles.
WHEATSTONE BRIDGE
This early test instrument, and its nulling concept, has been used in countless other test instruments since. The electrical circuit is simply two voltage dividers in parallel with a galvanometer between the dividers. These devices typically are in the form of a diamond [Fig. 8].
The “bridge” concept of this device has been exploited once AC power
was “invented”. A “bridge rectifier” was developed to convert AC to DC power. This device is a common component in nearly all power supplies in everyday electronics we use today.
WHEATSTONE BRIDGE FUNCTIONING
To understand how a Wheatstone bridge works, you must understand how a voltage divider works: Here are two simple voltage divider circuits [Fig. 10], one on the left and another on the right:


A battery bank of 100 volts is applied to two resistors in series. The sum of resistance for each divider is 1,000 ohms (750 + 250 on the left, and 500 + 500 on the right). The current flowing through each divider is derived from Ohm’s Law: current = voltage/resistance I =V/R = 100/1000 = 0.1A. The voltage drop across each resistor is also derived from Ohm’s law: V= I * R , so for the 750 ohm resistor the drop from 100V = 0.1A * 750ohms = 75 volts. So, the voltage enters the 750 ohm resistor at 100V and exits at 25V due to the 75V drop. Likewise, the 25ohm resistor has a 25V drop so the voltage enters at 25V and exits at 0V. This is similar for the two 50ohm resistors where each drops 50V.


Fig. 10 Two Voltage Dividers
Fig. 11 Two Voltage Dividers (variation on right)
Fig. 12 Wheatstone Bridge Circuit
Fig. 9 Wheatstone Bridge
BACK REFLECTION
Now, if we change the resistances of the resistors in the right divider [Fig. 11], the current through the divider will change but the voltage dividing, and proportional ratios of voltage and resistance remains. In this case, the resistors used are 7,500 ohms and 2,500 ohms for a total resistance of 10,000 ohms. So, the current reduces to 0.01A.
Now, if we place a current measuring galvanometer between the two voltage dividers [Fig. 12], no current would flow through it, as each end is the same 25 Volts. You need a voltage difference before current will flow. This is the “nulling” (zero flow) concept that is the centerpiece of the Wheatstone bridge; and of course, the connection through the galvanometer resembles a “bridge” between the two divider circuits.
Now that you are almost an expert, to save connections, and for efficiency, the circuit above is reduced to this [Fig. 13]. The classic diamond-like shape of the Wheatstone Bridge. Of course, there is a bit of math needed to use this instrument. It is not too scary: When a Wheatstone bridge is nulled and the current through the bridge is 0A, R1 * R4 = R2 * R3. So, in Fig. 13 we have 750 * 2500 = 250 * 7500. So, if we are missing one of the values, we can find it by balancing the

bridge and then solving. If we did not know R4, the solution would be R4 = (R2 * R3) / R1 = (250 * 7500) / 750 = 2,500 ohms. Pure magic.
So, what does this have to do with finding a fault in a submarine cable? Let’s go back in time and solve a problem for a cable break between Ireland and England. Let’s assume the cable is 100 nautical miles (nm) in length and the resistance of the copper wire is 50 ohms per nm. This gives a total resistance through the cable of 5,000 ohms [Fig. 15].
If we were in the cable factory and had to measure the cable resistance
with our Wheatstone Bridge, the configuration would be [Fig. 16]:
For the above, R2 & R3 were arbitrarily chosen, they could be any value. Once they are in place, then the unknown Rcable would be found by changing R? until the Galvanometer bridge shows 0 current (null current). In this case R? would be 100 ohms to null the current. Rcable = (R2*R3) / R? = (1000 * 500) / 100 = 5000 ohms.
Now that we have completed a basic factory measurement, let’s go to the field and assume we are in the station and the cable has broken somewhere. Let’s use the Wheatstone bridge to find the location [Fig. 17]:
In this case, we connect the Wheatstone bridge to the faulted cable and assume the faulted end of the cable is exposed to the ocean and is effectively grounded. At this point we do not know the resistance of the cable (but it is really 2,000 ohms), so that is sensed by the instrument. We keep our R3 at an arbitrary 500 ohms, and R2 at an arbitrary 1,000 ohms. We then vary R? while observing the galvanometer and stop when the Galvanometer shows no current through the bridge. This gives R? = 250ohms. We then solve for Rcablefault by RCF = (1000 * 500) / 250 = 2000 ohms. So, the resistance of the cable from the
Fig. 13 Wheatstone Bridge Circuit (Typical Form)
Fig. 15 Submarine Cable 100 nautical miles and 5,000 ohms
station to the fault is 2,000 ohms. So, at 50 ohms per mile, the fault is 40 nm from the station.
Tests can be run from the far end and hopefully they resolve to the fault at 60 nm. It is possible that the fault is not well grounded to the ocean and has resistance. If the far end reported the fault at 62 miles away, we could assume the fault resistance to be 50 ohms and the distances to the fault to be 39 nm and 61nm. Also, note that testing with negative voltage to the ocean improves the conductivity at the fault. Testing with positive voltage to the fault will “seal it” due to electrochemical depositing of an insulating green layer of Copper Chloride over the exposed copper conductor [Fig. 18]. This will change the resistance of the



measurement, and it will creep higher and higher in resistance until it shows “open” (infinite resistance). If you were using the Wheatstone bridge and testing positive voltage into the fault, the continuously rising resistance of the cable would drive you mad!
An important lesson for all working with contemporary submarine cables: one should always set the power feed
polarity to negative when powering into a fault (for measurements). If you discover that your repeaters are unidirectional and your power feed cannot be repolarized to negative, then any minimal savings for this feature-loss are costing you in fault locating accuracy for the 25 to 30 years of system operations. Any new submarine cable system should be specified to have bidirectional polarity powering capability. A lesson from 175 years ago. STF

LEGAL & REGULATORY MATTERS
KEY PRINCIPLES FOR WRITING EFFECTIVE LEGAL OPINIONS
BY ANDRÉS FÍGOLI

Writing legal opinions is a pillar of legal practice, requiring not only a deep understanding of the law, but also strong analytical and critical thinking skills. Legal professionals are tasked with providing objective, well-reasoned analysis that helps clients, businesses, or the public make informed decisions. As such, producing effective legal opinions goes beyond the surface of simply interpreting the law; it requires consistency, independence and a pragmatic approach to ensure both accuracy and clarity.
This article explores these essential principles in the world of submarine
cables, along with practical tips on how to avoid common pitfalls, such as implicit bias and external influences, that can compromise the value of a legal opinion.
I. CONSISTENCY AND CREDIBILITY IN LEGAL OPINIONS
Consistency in legal opinions is crucial to building a reputation for reliability. A lawyer who contradicts his or her own previous publications or statements without adequate justification risks damaging his or her own credibility as well as that of his or her client. For example, if a lawyer has publicly supported a particular inter-
pretation of a statute, it is essential that future opinions either support that interpretation or, if there is new evidence or precedent, clearly explain the reasons for a revised position. This approach ensures consistency and reinforces the authority of the lawyer’s perspective.
Imagine a submarine cable owner deciding to proceed with dispute resolution proceedings against another carrier for breach of an IRU agreement based on the interpretation of that agreement by its external counsel. The surprise may come during a hearing when the defendant cites the law journal article written by the plaintiff’s
external counsel many years ago with the opposite interpretation. To maintain consistency, it is therefore essential to thoroughly review previous opinions and publications on the same or related issues before finalising a new opinion.
It is still a famous anecdote in Uruguayan courts that a young lawyer lost an important case against his former famous professor from the law school, where the latter used arguments that were exactly the opposite of those claimed in the many textbooks he had written for students. The defeated lawyer approached him after the final judgement and asked him about this contradiction, and the senior academic replied from his victorious podium without regret that money matters and that justice is the responsibility of the judge and not his priority.
Of course, the solution is not to write academic articles without substance or papers without a personal approach, merely quoting the opinions of other academics, without risking criticism for oneself or even jeopardising future cases that may be involved. Lawyers, as champions of advocacy among all other professions, should not behave like peacocks who just show off their feathers. It is a matter of upholding one’s principles from the outset, during the soul-searching process of deciding whether or not to take on a new client, knowing that he will need the services of another colleague who will have more appropriate arguments for that client’s interests.
II. CONFIDENTIALITY AND PUBLIC DISCOURSE
Confidentiality is central to the practice of law. Most legal opinions, especially those intended for internal
or client-only use, contain sensitive information that must be protected. However, any lawyer should also be careful not to approach a legal problem with such a view of his or her own beliefs and moral values that such an opinion might one day be made public.
During my internship in a law firm in Uruguay, there was a well-known quote by one of its founders from the beginning of the last century, Dardo Regules, inspired by ancient Greek philosophy, that one must be able to proclaim loudly the same opinion in the Plaza Independencia, Montevideo’s most important public square.
In plain English, this means that a company should not pretend to have a lawyer to advise it on illegal actions such as greenwashing the publicity for a new submarine cable system. Other short-term strategies to obtain speedy cable landing permits, such as lying or deliberately omitting to give important information to government officials in order to obtain such permits, only prove to boomerang against such external lawyers’ trust and confidence relationship, which is essential to properly serve other future clients in the future.
III. INDEPENDENCE OF JUDGMENT AND PROFESSIONAL OBJECTIVITY
Legal professionals are often employed by firms, government agencies or corporations. However, maintaining independent judgement is essential to providing unbiased, credible legal opinions. A sound legal opinion should be based on the law and analysis of the facts, not on institutional interests.
If a lawyer is hired by a government to assess whether its digital agenda and real-world practices effectively
promote the installation of new cables, such a legal opinion should be based on real-world practice, not on reading an outdated official website. Similarly, academic research studies may be funded by OTTs when landing in a new country to support a digital inclusion agenda, but this does not mean that the researcher must use misleading indicators or unreliable statistics.
Legal experts must critically evaluate sources of information and avoid being swayed by propaganda or media narratives, especially in sensitive cases such as recent cable damage. By maintaining objectivity, they can provide balanced and accurate assessments, even in complex scenarios with political implications.
Here are some examples of how the media might report on two hypothetical sabotage incidents involving cable damage. In the first, local fishermen deny involvement in damaging a cable and witnesses report seeing a foreign submarine nearby. Here, objective analysis requires checking the facts rather than assuming the nationality of the submarine on the basis of speculation and further suspicion of the local fishermen, who are statistically the prime suspects in such incidents.
In the second case, a fishing trawler from a rival nation is seen leaving an exclusive economic zone after suspicious activity near the damaged cable. Clearly, simply zigzagging in a cable zone is not enough to prove deliberate misconduct when such a course is taken in an attempt to recover lost fishing gear. Rather than presuming guilt on the basis of nationality, the lawyer should evaluate the evidence impartially, especially if other trawlers

from the coastal State have fished in the same cable protection zone.
In both cases, contacting reliable sources or conducting an independent investigation can provide clarity and avoid speculative conclusions. Otherwise, the media coverage of these cases would simply be propaganda for a particular government. Subsequently, they would be cited by respected academic researchers in their papers as a long list of alleged sabotage in the midst of geopolitical tensions, simply because they came from official sources. The lack of esprit critique, which is supposed to be the essential basis of any university study, may be due to pervasive apathy or lack of willingness, or even other darker motives such as pushing an arms-race agenda.
Unfortunately, this has recently led some researchers to theorise about the submarine cable industry without any real factual basis. A path that takes them away from real practice when it comes to proposing realistic solutions to everyday problems in the industry, such as proposing 24/7 maritime surveillance to protect submarine cables in the vast oceans.
In some situations, the best response may be to refrain from expressing an opinion, particularly where there is insufficient evidence or where the issue is speculative. This caution ensures that the legal professional does not compromise his or her integrity or credibility by engaging in discussions with inconclusive evidence. This is particularly important when the press and media need some professionals
or experts to give their opinion on a recent cable outage.
IV. PRAGMATIC SOLUTIONS OVER EMPTY RHETORIC
Legal opinions should focus on pragmatic solutions rather than abstract theories or superficial recommendations. Clients and institutions seek legal advice that they can apply in real-world scenarios, not generalities or “empty talk.”
Rather than making general suggestions such as “continue the dialogue” in a study on how to improve cable protection, a more effective recommendation might be to suggest specific pragmatic measures that can be measured in the future. This specificity adds value and ensures that the advice is not just theoretical but actionable.
In addition, it is important to read and understand the law itself, rather than reading other people’s opinions about it, before commenting on new legislation. Understanding the law at first hand is crucial to developing an independent opinion, allowing the lawyer to form a sound, independent viewpoint and ensuring that he or she is not simply echoing the interpretations of others without critical evaluation. As seen above, many think tanks and research centres publish opinions on legal issues and may be influenced by specific agendas, funding sources or editorial lines. It is therefore prudent to consider their potential biases when citing these sources, and to ensure that they are transparent about their funding and affiliations.
Finally, in any litigation, the external lawyer should provide clarity about the options and next steps available. A lengthy legal process may be appropriate for other industries, but not for wholesale telecommunications, where decisions need to be made quickly in line with market developments. This means that the legal adviser has to give clear, holistic advice to the client, sometimes recommending a bad deal rather than a good lawsuit, instead of thinking about how to get more legal fees.
CONCLUSION
The role of a legal opinion is to provide clear, objective and actionable insights. Maintaining integrity in legal opinions is a long-term strategy for any lawyer who wants to be seen as independent. By adhering to principles such as consistency, confidentiality, independence, pragmatism and objective analysis, legal professionals can ensure that their opinions are valuable, trustworthy and professionally sound.

Welcome to this issue’s advertising and marketing tip! In the last issue I covered the importance of consistent branding to build trust, make your campaigns cohesive, and to define your company’s sense of purpose. This month I want to focus on what you should do once you have a marketing campaign running and you’re receiving clicks.
Let’s pretend you are running a campaign with SubTel Forum (what a great choice!), with both banner advertising featured on the website and an advertisement in three issues of the magazine. You have created a great value proposition, your call to action is on point, and your branding is consistent across all ads. You are crushing it! Now readers and site visitors are clicking or scanning QR codes – what’s next?
The first step to leveraging those extremely valuable clicks is to ensure a retargeting pixel is active on your website. A retargeting pixel captures website visitors and allows you to target them with additional digital ad campaigns. This helps push them further down your marketing and sales funnel. There are many companies that enable businesses of all sizes to utilize retargeting technology including Google, AdRoll, and Retargeter. We also run our own platform and can help.
If you are already retargeting your website the next step is making sure the landing page provides a clear next step
for the site visitor. Basically, what do you expect someone that has clicked your ad to do once they visit? If you would like them to view a demo or register for a webinar make sure that is very clear and all details, including the registration fields, are above the fold.
If you do expect visitors to provide their contact details make sure to minimize what is required. The fewer required details the more registrations you will receive. In most cases an email address and name should suffice. You can then easily locate the job title, company name, etc. based on the name and email address.
While not comprehensive, the two recommendations above should help you more effectively capture the leads you’re working hard to generate. As always, I hope you find these tips helpful, and if you are seeking to put all of them into action there is simply no better place to facilitate connections and showcase your product or service than SubTel Forum properties. Contact me to find out the latest, most effective ways to make a connection. STF
