40G QSFP+ ER4 1310nm 40KM Optical Transceiver Module converts 4 inputs channels (ch) 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.
4 CWDM channels are 1271, 1291,1311 and 1331 nm
Single +3.3V power supply
QSFP+ MSA compliant
Up to 40km transmission
40G Ethernet
Infiniband 4X SDR DDR QDR
40G Telecom connections
