Nonlinearity-Free DP-144QAM-PCS Beyond-1Tbps Transmission over 100km AR-HCF for OTN-Based Decentralized Intelligent Training

Single-channel DP-144QAM-PCS 1.09Tbps transmission over 100km AR-HCF with $0.164 \mathrm{~dB} / \mathrm{km}$ at 1550nm for decentralized intelligent training was experimentally verified for the first time. Nonlinearity-free input power is improved from 7 dBm for G.652 to above 15 dBm.
