We demonstrate 96GBaud-DP-PCS-64QAM and 118GBaud-DP-PCS-128QAM signal transmissions using the modified 8×2 WL-MIMO equalizer. Compared with the conventional equalizer using the same complexity, the ROSNR and convergence speed are improved by 2.75dB and 67% respectively, and the FO tolerance is above 2GHz in the 96GBaud-DP-PCS-64QAM case.
