104 Tbps/carrier Probabilistically Shaped PDM-64QAM WDM Transmission over 240 km based on Electrical Spectrum Synthesis

Abstract

We demonstrate 1.04-Tbps/carrier net-rate 125-GHz-spaced 9-WDM (9.3-Tbps) transmission over 240-km using 120-GBd probabilistically shaped PDM-64QAM generated by electrical spectrum synthesis technique with in-house ultra-broadband bandwidth doublers with the spectral efficiency of 8.3 bps/Hz.
