詳細介紹
40G QSFP+ LR4 10Km 1310nm LC Optical Transceiver
The QSFP+ 40G LR4 RQ-40G-LR4 is a transceiver module designed for10km optical communication applications. The design is compliant to 40GBASE-LR4 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.
