Abstract: We experimentally demonstrate probabilistically shaped 64-ary quadrature-amplitude-modulation (64QAM) 50-GHz-grid wavelength-division-multiplexing (WDM) transmission with a bit rate of 400-Gbit/s per channel over 3,600-km Raman-amplified ultra-large effective area fiber (ULAF). Our results show that the probabilistically shaped… read more here.
