H3C QSFP-40G-ER4-SM1310 Compatible 40G QSFP+ ER4 Transceiver Module (1271nm, 1291nm, 1311nm, 1331nm SMF 40km LC DDM)

The QSFPP-40G-ER4 is a transceiver module designed for 40km optical communication applications. The design is compliant with 40GBASE-ER4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDMoptical 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 4CWDM channels signals and converts them to 4-channel output electrical data.
