100G QSFP28 BiDi ER1 single fiber optical transceiver modules are designed for use in 100G Ethernet links over 40km single mode fiber. 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 of the module is compliant with the OIF CEI-28G-VSR and QSFP28 MSA.
