This product is a transceiver module designed for 40km optical communication applications. The design is
compliant to 40GBASE-ER4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (4ch) of
10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical
transmission. Reversely, 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.
