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 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.
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.
