Wavesplitter’s WST-QS28-FR-C, 100GBASE-FR single lambda (wavelength), four channel, hot pluggable optical transceiver is a cost focused solution for 100GE links for up to 2km over single mode fiber (SMF). It combines 4x 25 Gb/s NRZ electrical lanes into one 53.125 GBd PAM4 optical channel in compliance with IEEE 100GBASE-FR. Superior performance and reliability is achieved through Wavesplitter’s advanced transmitter and receiver design using a cooled EA-DFB-LD and a PIN PD with low-power TIA for an average power consumption of 3.5W. The WST-QS28-FR-C supports a RS- FEC (544,514) encoder/decoder function for interoperability with 100GAUI-4 and CAUI-4
