The design is compliant to 1000GBASE CWDM4 MSA standard. The module converts 4 inputs channels (CH) of 25Gb\/s electrical data to 4 CWDM 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 CWDM channels signals, and converts them to 4 channel output electrical data.  The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. 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. Host FEC is required to support up to 2km fiber transmission. The product is designed with form factor, optical\/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference."}
