400GBASE-FR4 OSFP 400G 2km Transceiver

400GBASE-FR4 OSFP 400G 2km Transceiver The module incorporates 4 independent channels on CWDM4 1271/1291/1311/1331nm center wavelength, operating at 100G per channel. The transmitter path incorporates a quad channel EML driver and EML lasers together with an optical multiplexer. On the receiver path, an optical de- multiplexer is coupled to a 4 channel photodiode array. A DSP basis gearbox is used to convert 8 channels of 25GBaud PAM4 signals into 4 channels of 50GBaud PAM4 signals and also an 8-channel retimer and FEC block are integrated in this DSP.
