Abstract

We experimentally demonstrate a single-carrier 400G solution based on 51.25-GBaud PDM-32QAM signal at 6.15-b/s/Hz SE over 1200-km transmission distance. Training assisted pre-compensations and both transmitter and receiver based look-up table are employed to mitigate channel bandwidth constraint and component nonlinearity impairment.
