1.0-Tb/s/λ 3840-km and 1.2-Tb/s/λ 1280-km Transmissions with 168-GBaud PCS-QAM Signals Based on AMUX Integrated Frontend Module

We successfully demonstrate 1.0-Tb/s/λ 3840-km and 1.2-Tb/s/λ 1280-km long-haul transmissions in 4.2-THz full C-band 175-GHz-spaced WDM configuration with improving signal noise tolerance using 168-GBaud high-symbol-rate PCS-16QAM and PCS-36QAM signals generated by our AMUX-integrated frontend module. © 2022 The Author(s)
