Approaching the Non-Linear Shannon Limit
TL;DR: In this article, the authors review the recent progress of information theory in optical communications and describe the current experimental results and associated advances in various individual technologies which increase the information capacity, and confirm the widely held belief that the reported capacities are approaching the fundamental limits imposed by signal-to-noise ratio and the distributed nonlinearity of conventional optical fibres, resulting in the reduction in the growth rate of communication capacity.
