40Gbps QSFP+ CWDM4 Transceiver

The CWDM4 QSFP+ transceiver module designed 2km fiber optical communications.
The CWDM4 QSFP+ transceiver module designed 2km fiber optical communications.

The CWDM4 QSFP+ transceiver module designed for 2 km fiber optical communications. The transceiver is compliant with 100GBASE CWDM4 MSA standard. The module converts 4 channels of 10 Gbps data to 4 CWDM optical signals, and multiplexes them into a single channel for 100 Gbps optical transmission. As the Receiver side, the module optically de-multiplexes a 40 Gbps input into 4 CWDM channels signals, and converts them to 4 channels output electrical data.

The central wavelengths of the 4 CWDM channels are 1271nm, 1291nm, 1311nm and 1331nm as defined CWDM wavelength grid defined in ITU-T G.694.2.
