Transmission of 36-Gbaud PAM-8 Signal in IM/DD System using Pairwise-Distributed Probabilistic Amplitude Shaping

摘要

We experimentally demonstrate the transmission of 36-Gbaud probabilistically-shaped PAM-8 signal over 10-km link. The performance measured after FEC decoding and inverse distribution matcher shows that the receiver sensitivity is improved by >1 dB compared to uniform-distributed signals.
