Accelight’s 100Gbps QSFP28 transceiver module is designed for optical communication applications in 100 Gigabit Ethernet links over 40km single mode fiber. This product converts 4 channels of 25Gbps (NRZ) electrical input data to 4 channels of 25Gbps (NRZ) LAN-WDM optical signals. Reversely, on the receiver side, 4 channels of LAN-WDM optical signals of 25Gbps (NRZ) converts to 4 channels of 25Gbps (NRZ) electrical output data. The central wavelengths of 4 channels are members of the frequency grid for 100 GHz spacing and above defined in ITU-T G.694.1. And per channel operating at 25Gbps. The electrical interface of the module is compliant with the CAUI-4 interface as defined by IEEE 802.3bm, and the form factor, optical/electrical connection and digital diagnostic interface compliant with QSFP28 MSA and 100G 4WDM-40 MSA.
