We experimentally show that low-complexity channel-polarized multilevel coding enables up to 74% decoding-complexity reduction compared to concatenated codes over a 101-km 146-Gbaud probabilistically shaped 16QAM signal transmission.

We propose a low-complexity FEC scheme for PAS, which applies SD-FEC to unreliable bits converted by channel polarization. It reduces the complexity by up to 83% compared with changing the decoding iterations in PAS.

The EEPN penalty was measured separately from other factors in 5120-km transmission of 120-Gbaud 16QAM signal for different LO lasers. Digital subcarrier multiplexing suppressed the EEPN-induced NGMI deterioration by ~0.4 at 102,400 ps/nm.
