400GBase-DR4 Data Sheets

The 400G-DR4 QSFP-DD is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module designed for 500m optical communication applications. The module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 400Gb/s. Reversely, on the receiver side, the module converts 4 channels of parallel optical signals of 100Gb/s each channel for an aggregate data rate of 400Gb/s into 8 channels of 50Gb/s (PAM4) electrical output data.
