Know When to Choose the QSFP Transceivers for Your Network
Nowadays a huge majority of the traffic 40G/100G is operating globally; the data centers and business network operators are moving towards the adoption of the 100GbE connectivity or more to satisfy their bandwidth needs. For the high speed connectivity they have to look for right type of networking equipments. The fiber optical transceivers are one of the commonly used equipments for achieving high speed connections. You can look for the CFP transceivers that are hot-pluggable devices for the high speed 100Gbps Ethernet applications and are useful in the data and telecommunication networks. Apart from that you can look for SFP transceivers or 40G CFP transceivers. If you are planning to choose a 40G CFP transceiver such as the QSFP Transceiver then the first thing you
need to know is how it is structured and when to choose it. The 40G CFP transceiver is mostly 4x10G and is not over the single pair but is over four pairs of the fiber. Whereas the 100G is mostly 10x10G and is over 10 pairs of fiber or 4x25G and is over 4 pairs. Both of them use the MPO or MTP connectors and so all the 8/20 strands required are connected into a single convenient connector. The 100G CFP transceiver module created for metro networks have a long transmission distance. Relevant CFP transceiver is considered to be cost competitive along with a 100G direct detection CFP that make use of 4x25Gbps wavelengths. The QSFP transceivers are a new MSA or Multi Source Agreement designed for high-speed applications like 40GBASE and they offer 4 channels data in a single pluggable interface. These transceivers are one type of 40G transceiver and the channels are capable enough in transferring the data at 10Gbps and even supports 40Gbps. When compared with any standard SPF+ modules these transceivers have high density and they even cost less. They are designed for the applications with extremely high-density having stacked and organized configurations. There are number of benefits in choosing the QSFP transceivers. As this type of transceiver integrates 4 high capacity, individual fiber receiving and transmitting channels, the density of its ports is increased and total system price is reduced. When compare to the ports of traditional SFP transceivers it has three times high density port. Due to that it replaces 4 standard SFP modules in a place that is just 30% larger than one SFP. Another benefit of this transceiver is that you can install them in different standards. That is these transceivers support the Fibre Channel, Ethernet, SONET/ SDH standards and InfiniBand with data rates of up to 5Gb/s per a single channel. The platform is potential for combined high volumes and enhanced economics obtained from various applications with susing the same transceiver. Depending on the distance needs and type of the fiber you can choose a right type of QSFP Transceiver from the available types. These
transceivers are divided into various categories based on different criteria. They are classified by the media of transport such as the copper, single mode fiber or SMF and multimode fiber or MMF. These three types of transport media are most common ones in the 40Gigabit Ethernet. Each type of the transceiver will use different transport media. Based on the Ethernet standards the common types of 40 Gigabit Ethernet media system includes QSFP-40G-LR4, QSFP-40G-CR4 and QSFP40G-SR4. There may be different connector interfaces for the QSFP transceivers. By using different technologies various types of connectors can be installed into the 40 Gigabit Ethernet. Common types are the Duplex LC, MPO/MTP and MPO. The MTP and MPO are usually interchangeable. Transmission distance of the QSFP transceivers is mostly either long range or short range. The QSFP transceivers of short range can support the link lengths of 100m and 150m over the OM3 multi-mode fiber and OM4 multi-mode fiber. While the long range type can support a transmission length of 40km. Wavelength of the channels of these transceivers can be same or different from one another. Using the 40Gigabit Ethernet is becoming popular in recent times and different types of transceivers are coming up with various features. So while selecting the QSFP transceivers it is important to know your requirements for finding the right one.
