100 GBAUD PAM4 LINK WITHOUT EDFA AND POSTEQUALIZATION FOR OPTICAL INTERCONNECTS

We achieve 300 Gbps line rate transmission with 100 Gbaud PAM8 over 400 meters of SSMF in C-band. We also demonstrate 100 Gbaud PAM4 400 meters link below the 7% HD-FEC limit of 5∙10 -3 without optical amplification and post-equalization
