T1-QSFP28-100G-SR-LC50 is a transceiver module designed for 35M/50M on OM3/OM4 optical communication applications. It’s design is compliant with IEEE 802.3-2012 Clause 88 standard IEEE 802.3bm CAUI-4 chip to module electrical standard ITU-T G.959.1-2012-02.
The module converts 4 inputs channels (ch) of 25.78 Gbps to 27.95 Gbps electrical data to 4 lane 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 lane 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, multi-mode fiber (MMF) has to be applied in this module.
