Accelight’s QSFP-DD 4*100Gbps transceiver module is designed for optical communication applications in 400 Gigabit Ethernet links over 500m single mode fiber. This product converts 8 channels of 50Gbps (PAM4) electrical input data to 4 channels of 100Gbps (PAM4) parallel optical signals. Reversely, on the receiver side, 4 channels of parallel optical signals of 100Gbps (PAM4) converts to 8 channels of 50Gbps (PAM4) electrical output data. The central wavelengths of 4 parallel channels are 1310nm, and per channel operating at 100Gbps. The electrical interface of the module is compliant with the 400GAUI-8 interface as defined by IEEE 802.3bs, and the form factor, optical/electrical connection and digital diagnostic interface compliant with QSFP-DD MSA.
