Audited Supplier The QSFP28-100G-LR4 is a transceiver module designed for 10km optical communication applications. The design is compliant to 100GbASE-LR4 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 25.78 Gbps 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.
The central wavelengths of the 4 lanes are 1270 nm, 1290 nm, 1310 nm and 1330 nm . It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module.
