The module converts 4 channels of 100Gbps (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 100Gbps operation for an aggregate data rate of 400Gbps.
On the receiver side, the module converts four 100Gbps channels of parallel optical signals for an aggregate data rate of 400Gbps into four channels of 100Gbps(PAM4) electrical output data. An optical fiber cable with MPO-12 connector can be plugged into the OSFP 400G SR4 module receptacle.
