This FIBERSTAMP 400G OSFP-RHS FR4 product is designed for 2km optical communication applications. The module converts 4 channels of 100Gb/s (PAM4) electrical input data to 4 channels of CWDM optical signals, and multiplexes them into a single channel for 400Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 400Gb/s optical input into 4 channels of CWDM optical signals and converts them to 4 channels of 100Gb/s (PAM4) electrical output data.

The module incorporates 4 independent channels on CWDM4 1271/1291/1311/1331nm center wavelength, operating at 100G per channel. The transmitter path incorporates 4 independent EML drivers and EML lasers together with an optical multiplexer. On the receiver path, an optical de- multiplexer is coupled to a 4-channel photodiode array.

It is a cost-effective and lower power consumption solution for 400GBASE data center. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The module offers very high functionality and feature integration, accessible via a two-wire serial interface.
