100G 1310nm 2KM QSFP28 CWDM4
100G, 1310nm, 2KM, QSFP28, CWDM4
100G 1310nm 2KM 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 channel is recovered by a PIN photo-detector and trans-impedance amplifier, retimed.

The central wavelengths of the 4CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDMwavelength grid defined in ITU-T G.694.2. In the transmitter side, the fourlanes of optical data channels are optically multiplexed by the integratedoptical multiplexer. In the receive side, the four lanes of optical datachannels are optically de-multiplexed by the integrated optical de-multiplexer.Each data channel is recovered by a PIN photo-detector and trans-impedanceamplifier, retimed.
The product is designed with form factor,optical/electrical connection and digital diagnostic interface according to theQSFP28 Multi-Source Agreement (MSA) and compliant to CWDM4 MSA. Host FEC isrequired to support up to 2km fiber transmission.
