    40GBASE-LR4 40G Ethernet

     

    3 General

     

    This product is a high performance 40Gbps transceiver module designed for optical communication applications. It converts 4 channels of 10Gb/s electrical input data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. On the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data.
