QSFP Optical Module Overview
The LNK-QSFP28-SR4 is a transceiver module designed for 100m optical communication applications. The design is compliant to 100GbASE-SR4 of the IEEE 802.3-2012 Clause 88 standard IEEE 802.3bm CAUI-4 chip to module electrical standard ITU-T G.959.1-2012-02 standard. The module converts 4 inputs channels (ch) of 25.78Gbps to 27.95Gbps electrical data to 4 lanes optical signals, and multiplexes them into a single channel for 100Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 100Gb/s input into 4 lanes signals, and converts them to 4 lanes output electrical data.
