100GE/OTU4 QSFP28 ER4 Lite DML 40km Optical Transceiver

This product is a 100Gb/s transceiver module designed for optical communication applications compliant to QSFP MSA, 4WDM-40 MSA, 100GBASE-ER4 Lite, and OTU4 standards.

The module converts 4 input channels of 28Gb/s electrical data to 4 channels of LAN-WDM optical signals and then multiplexes them into a single channel for 112Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 112Gb/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. The product has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
