This product is a transceiver module designed for 2m-10km optical communication applications.

The design is compliant to 40GBASE-LR4 of the IEEE P802.3ba standard.


The module converts 4 inputs channels (ch) of 10 Gbps electrical data to 4 CWDM optical signals and multiplexes them into a single channel for 40 Gbps optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gbps input into 4 CWDM channels signals and converts them to 4 channel output electrical data.


The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G694.2. It contains a duplex LC connector for the optical interface and a 148-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module.


The product is designed with form factor, optical/ electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
