100G QSFP28 CWDM4 2km Optical Transceiver

100G QSFP28 CWDM4 Optical Transceiver is designed for use in 100 Gigabit Ethernet links on up to 2km of Singlemode Fiber. It is compliant with the 1000GBASE CWDM4 MSA standard. The Optical Transceiver converts 4 inputs channels (ch) of 25Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 100Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 100Gb/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 G.694.2. It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, Singlemode Fiber (SMF) has to be applied in this Optical Transceiver. Host FEC is required to support up to 2km fiber transmission.
The Optical Transceiver is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference .
