The 40Gb/s QSFP+ER4 is a transceiver module designed for 40km optical communication applications. The design is compliant to 40GBASE-ER4 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. It contains a duplex
LC connector for the optical interface. To minimize the optical dispersion in the long-haul system, single-mode fibre (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
