The transition from 40 G to 100 G is another requirement for optical transceiver development. Modern large-scale data centers usually use 10G access ports to access the switching network using 40G. However, 25G access ports and 100G switching networks will be rapidly advancing in the next few years. In data centers, shape and specification are important factors in determining the application of optical modules. Today, the data center has unified the use of a small pluggable module (SFP, Small Form Factor Pluggable) to achieve server access, four channels QSFP transceiver (Quad Small Form-factor Pluggable) is used for interconnection between switch nodes. In addition, high-speed DAC (Direct Attach Cable) is often used to access the port distance less than 5 meters, while the AOC (Active Optical Cable) can be used for further distance connection.
Small pluggable upgrade optical module (SFP+) plays a crucial role in 10G data transmission with its compact size, high performance and cost saving advantages. In the past years, SFP+ transceivers have been widely used in 10G access ports. However, the good scenery of SFP+ is not long, because when the access speed increases to 25G and 10G, the access port will transition to SFP28. In addition, the 25G LAN Emulation ecosystem will be expected to use in the next generation of enterprise network application, which will promote requirements for the SFP28 optical transceiver in the single-mode fiber transmission, and running distance is expected to reach 10 to 40 km.
The QSFP transceiver supports 4 parallel electrical interface channels and operates at a speed of 4 x 10 Gbps. It is a parallel fiber transceiver. Today, 40G QSFP+ module is widely used in data center switching network, and with the speeding up deployment of 40G Ethernet of data center, 40G QSFP+ optical transceiver applications will continue to strengthen, especially to achieve high-density 10G interface interconnection through the 40G branch direct connection. However, IHS Infonetics released a research report, the research report said that as the data center in 2016 will gradually transition from 40 G to 100 G switching network, QSFP28 optical transceiver will be deployed on a large scale.
At present, CFP4 and QSFP28 optical transceiver seem to be neck and neck. QSFP28 fiber optic transceiver occupies the advantage of density, while CFP4 has higher maximum power dissipation, which makes it reach farther transmission distance. In addition, there is another trend in the data center, that is, almost all link lengths are less than 2 km. Therefore, for the design of interconnection and high density switch, even QSFP28 still has technical problems to be solved, but since it is almost the same size with QSFP+, which seems to be the preferred application in data center.
