How the Use Fiber Optical Transceivers Affect the Server Technology The present data centers and networking environments are undergoing an infrastructure transformation that require higher speeds, greater scalability and a higher level of performance in order to meet the demands of the business. As the speed and performance need increases, the use of optical transceivers has become an integral part of the system design.

The data centers make use of the optical server technology. The data center are used in the processing of tons of information with the need to retrieve data from at high speeds. This aspect requires the design of the transceivers to be optimized. Most of these centers ate connected with 100Mbps or higher and continue to have an increasing demand for higher bandwidth. The optical transceiver technology needs to meet the bandwidth requirement for the storage applications, the switch applications and the server applications. The transceiver design margins and the parameters vary widely and can determine a form of optimization, reliability and performance of these centers.

Why use Transceiver Modules in Data Centers The demand for the 100G components and modules is a big drive for the growth of these centers. The use of the optical technology provides greater performance and optimization in areas where other forms of communication cannot deliver. - They provide high system reliability qualifications and certification testing.

How Optical Transceivers Affect Server Technology

1. The Power Consumption The transceivers with larger power consumption present thermal challenges and limit the EPS chassis density. In the date centers, there is preferred use of the photonic integrated circuits (PIC), low threshold data and low switching energy in order to reduce the power consumptions. The use of smaller transceivers have made the optical power consumption to drop from 10W to 3W and this is a significant stride that has enabled the designers to get more of the transceiver technology. The lower power consumptions mean that there are lower prices on the design and power costs. 2. Transceiver Size and Design


The packages that are used for the design of the optical transceivers are shrinking. This is a significant step that has allowed the overall footprint of the servers to be decreased resulting to the data centers to be more streamlined and smaller. When making considerations of the transceiver design, the port density is an important factor to look at. Most of the data centers consist of multiple racks of switching equipment that help the centers achieve high speed. In order to control the costs, the designers have made refinements to their design in a bid to improve the performance of the modules. 3. The Transceiver inefficiencies There are losses that are correlated with the use of the optical transceivers. There is an interference of the cross talking about the telecommunication channels. This calls for the designers and manufacturers to offer a more solid aid to help in achieving a better efficiency. The scientific and technological enterprises are all making in developing and offering optic fiber transceiver technology that is suitable for the data centers. For the electric signals of these modules, that need to be converted to optical signals, will have a better facilitation where the signals will be transferred from the server to server through the fiber cable. 4. Improving the Transceiver Technology Technology companies are coming up in a joint effort to develop optical transceiver technology that is specifically meant for the data centers. The devices will be able to convert electrical signals into the respective optical signals and allow the signals to be effectively transferred form one server to the other on the fiber optic cables. Some of the companies have introduced transceiver technologies that transmit data at 40 Gbps while others are making offers at 100Gbps.


The Data Center Architecture The data centers architecture is evolving to deal with an increasing amount of inside data. At the same time, the data center interconnects (DCI) are becoming increasingly important in large players controlling both ends of the link and the fiber itself. The introduction of the virtualization technology as allowed a single CPU to multi- process. The optical server technology has improved to support the amount of data that is being processed through the CPU to the other peripheral devices. With the use of optical technology, reaching high speed data transmission has been easy making the transceivers be excellence in terms of their performance. Why data centers and Enterprise are embracing high speed networking technologies. - Due to the growing complexity of the enterprise networks and the data centers. - Larger and more diverse data and higher quality expectations of SaaS - The rapid adoption of the 40G and 100G technologies thus creating a large opportunity for the optical vendors.


Trends in the Mega Scale Data Centers. The present data centers are being designed with the optical server technology in considerations. Greater emphasis is being laid on achieving greater speeds, high optimization and better performance. Below is a simple description of the defining characteristics, - Server migrating from 10G to 25G - 10G SFP+ demand migrating to 25G SFP 28. - 40G QSFP (4 X 10G optical) demand shifting to 100G QSFP 28 (4 X 25G). - Single mode fiber infrastructure is increasingly adopted in large data centers. - Routers and transport equipment continue to require 100G CFP and CFP2 for 10km applications. As the cloud industry expands, the experts in the field of technology can expect the optical transceiver technology to improve and advance in order to meet the speed requirements of the server technology. This is a promising trend because the transceiver manufacturers will try to improve the current transmission speeds and the operability. A reduction in cost of the optical transceiver is going to be witnessed, if the transceivers increase their port density. Designers are having the plan to upgrade their transceiver technology and the server technology. If all these plans are implemented, business owners can rest assured that their processing time will be conserved.
