The module incorporates 1 channel optical signal, operating at 100Gbps data rate. This module can convert 4 channels of 25Gbps (NRZ) electrical input data to 1 channel of 100Gbps (PAM4) optical signal and also can convert 1 channel of 100Gbps (PAM4) optical signal to 4 channels of 25Gbps (NRZ) electrical output data.The electrical interface uses a 38-contact edge type connector. The optical interface uses a Single LC connector.The high performance cooled EML transmitter and high sensitivity PIN receiver provide superior performance for 100Gigabit Ethernet applications up to 10km links.
