40 Gbps 40km QSFP+ ER4 Transceiver

The OSP-IN-E-40G-40 from OSP.com LLC 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 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 40 Gbps 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 1331nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. 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 the form factor, optical/electrical connection and digital diagnosti
