Abstract:
A transmission system with adjustable data rate for single carrier coherent optical transmission is proposed, which enables high speed transmission close to the Shannon limit. The proposed system is based on probabilistically shaped 64-QAM modulation formats. Adjustable shaping is combined with a fixed QAM modulation and a fixed forward error correction code to realize a system with adjustable net data rate that can operate over a large reach range. At the transmitter, an adjustable distribution...     »
