100G QSFP28 4WDM-40 DML 40KM


The module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN-WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 10Gb/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 APD receivers provide superior performance for 100-Gigabit Ethernet applications up to 30km links without FEC and up to 40km links with FEC.
