40G QSFP+ ER4+ 60Km DDM LC 光模塊
40G QSFP+ ER4+ 60km DDM Optical Transceiver
The RQ-40G-ER4+ is a transceiver module designed for 60km optical communication applications. The design is compliant to 40GBASE-ER4+ of the IEEE P802.3ba standard. The module converts 4 inputs channels of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission.
