16384-QAM TRANSMISSION AT 10 GBD OVER 25-KM SSMF USING POLARIZATION-MULTIPLEXED PROBABILISTIC CONSTELLATION SHAPING

We demonstrate the transmission of 10-GBd polarization-multiplexed probabilistically shaped 16384-ary quadrature amplitude modulation (16384-QAM) over 25.5-km standard single mode fiber (SSMF), with a net single-carrier bit rate of 223.8 Gb/s carrying 22.3 information bits/symbol/2-pol.
