This product is a 800Gb/s OSFP 2xSR4 optical module designed for 100m optical communication applications. The module converts 8 channels of 100Gb/s (PAM4) electrical input data to 8 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 800Gb/s.
On the receiver side, the module converts 8 channels of parallel optical signals of 100Gb/s each channel for an aggregate data rate of 800Gb/s into 8 channels of 100Gb/s (PAM4) electrical output data.
An optical fiber cable with dual MPO-12 connector can be plugged into the OSFP 800G SR8 module receptacle. Host FEC is required to support up to 100m fiber transmission.
