The module converts 4 input channels of 25.78Gb\/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 103.1Gb\/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 103.1Gb\/s optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of electrical data.  The central wavelengths of the 4 LAN WDM channels are 1295.56,1300.05,1304.58 and 1309.14 nm as members of the LAN WDM wavelength grid defined in IEEE 802.3ba.The high performance cooled LAN WDM DFB transmitters and high sensitivity PIN receivers provide superior performance for 100Gigabit Ethernet applications up to 20km links and compliant to optical interface with IEEE802.3ba Clause 88 100GBASE-LR4 requirements.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."}
