Track: 10. High-Speed Signal Processing, Equalization & Coding

Audience Level: All

Session Type: Technical Session

Description: In this study, high-speed serial link error propagation models and different Ethernet PMA/PCS schemes have been built and simulated to provide FEC performance analysis for 100/200/400GbE systems with 100+Gb/s per lane PAM4 interface. Different scenarios such as 1/(1+D) mod4 precoding, PMA bit multiplexing, symbol multiplexing and PCS RS codeword interleaving and their impacts on overall FEC performance will be discussed. Multi-part link where a single FEC shared between electrical and optical parts is studied as well. Advanced FEC schemes over current KP4 code will be explored at the end.

Takeaway: This study will provide comprehensive analysis for FEC performance for next generation 100Gb/s per lane 100/200/400GbE system.
