D-Link DEM-QX40Q-ER4 Compatible LINK-PP LQ-CW40-ER4C 40GBASE-T ER4 QSFP+ SMF Optical Transceiver Module Duplex LC(SMF, 1310nm, 40km, LC, DOM)


The QSFP+ transceiver is designed for 40km optical communication applications，which is compliant to 40GBASE-ER4 of the IEEE P802.3ba standard. The 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.
