The SiPhx HSD1-400-DR-C2S transceiver is designed for 500m optical communication applications, and is compliant with QSFP-DD MSA, CMIS 4.0, IEEE 802.3bs, and 400GAUI-8 standards. The 425 Gigabit signal is carried over four parallel lanes at 1310nm. The module’s transmitter converts 8-channel 53.125 Gbps electrical data to 4 parallel optical output signals, each supporting 106.25 Gbps. The receiver converts 4-channel 106.25 Gbps optical input data to 8-channel electrical output data.
