LANMexx’100G ER4 Lite 25km QSFP28 optical transceiver product is a 100Gb/s QSFP28 transceiver module designed for optical communication applications compliant to 100GBASE-ER4 Lite standard. The 100G QSFP28 ER4 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 of the 100G QSFP28 ER4 transceiver, the module de-multiplexes a 100Gb/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 EA-DFB transmitters and high sensitivity APD receivers of the 100G QSFP28 ER4 optical transceiver provide superior performance for 100Gigabit Ethernet applications up to 25km links without FEC. Commonly, this 100G QSFP28 ER4 product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA). Even the Datacomm 100G QSFP28 ER4 optical transceiver has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference, it is widely used in the 100G Ethernet and 100G Telecom connections.
