Mentech 100G QSFP28 CWDM4 integrates four transmitters and receivers into one module. 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. In the transmitter side, the four lanes of optical data
channels are optically multiplexed by the integrated optical multiplexer. In the receive side, the four
lanes of optical data channels are optically de-multiplexed by the integrated optical de-multiplexer.
Each data channels is recovered by a PIN photo-detector and trans-impedance amplifier, retimed.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface
according to the QSFP28 Multi-Source Agreement (MSA) and compliant to CWDM4 MSA. Host FEC is
required to support up to 2km fiber transmission.
