WDM Transmission of 600G Carriers Over 5,600 km with Probabilistically Shaped 16QAM at 106 Gbaud

摘要

We experimentally demonstrated 600G per-wavelength (848-Gbps coded line rate) probabilistically shaped 16QAM coherent WDM transmission over 5,600-km ultra-low-loss fibers with Raman amplification above the 27.5% SD-FEC threshold of 0.8 NGMI, attaining 27% transmission-distance improvement compared with regular-16QAM.
