SLQS28-100G-ERS is a transceiver module designed for 30km optical communication applications.

The design is compliant to 100GbASE-LR1 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 of 25.78Gbps electrical data to 1 lane optical signal channel for 100Gb/s (PAM4) optical transmission. Reversely, on the receiver side, the module an optical 100Gb/s (PAM4) input into 1 lane signal, and converts them to 4 lanes output electrical data.

The central wavelength is 1310nm. 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.
