The QSFP28 CWDM4 transceiver is a 100 Gbit/s pluggable module for 100GBASE Ethernet. The transceiver operates with four parallel data streams of 25.78 Gbps in order to provide an aggregated signaling rate of 103.125 Gbps. The four lanes are launched with center wavelengths of 1271 nm, 1291 nm, 1311 nm and 1331 nm and multiplexed onto single mode fiber. On the receive side, the four lanes of optical data streams are de-multiplexed by the transceiver and retimed.
The module is fully compliant with all QSFP28 related MSA’s described in SFF-8665 and Digital Diagnostic functions are available through an I2C interface. QSFP28-CWDM4 complies with IEEE 802.3 and 100Gbase-CWDM4
