100GBASE-ER4 QSFP28 1310nm 40km DOM Optical Transceiver Module

100Gb/s 100GBASE-ER4 40KM QSFP28 transceiver compatible with Juniper Huawei Brocade, Force10 Networks 100GBASE-ER4 (SMF, 1310nm, 40km)

LANMexx’ 100G  QSFP28 ER4  is a 100Gb/s transceiver module designed for optical communication applications compliant to Ethernet 100GBASE-ER4 Lite standard. 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 100Gb/s optical input into 4 channels of LANWDM 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 1309.14nm as members of the LAN WDM wavelength grid defined in IEEE802.3ba.The high performance cooled LAN WDM EA-DFB transmitters and high sensitivity APD receivers provide superior performance for 100Gigabit Ethernet applications up to 30km links without FEC and 40km links with FEC.

The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA).It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
