LINK-PP LQ-M3140-L24C 40Gbps QSFP+ Transceiver, Single Mode MPO 1310nm 20km Reach


The transceiver is designed for 20km optical communication applications,which compliant to 40GBASE-LR4 of the IEEE

P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 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 channels signals, and converts them to 4 channel output electrical data.
