Design Example – 800G FR-4 WDM for Ethernet Applications
This simulation setup demonstrates the transmission of 4*200G FR-4 WDM channels with 112.5 Gbaud as specified by the 800G Pluggable MSA technical specification . Four wavelengthseparated transmitters in the O-band emit a PAM4 signal each. The outer FEC encoder utilizes Reed-Solomon RS(544,514) coding. The setup shows the impact of bandwidth limitations on the system performance and the capability of the RS-based FEC. BER pre-FEC and post-FEC are used to evaluate the system performance.
