“…This compensation may take the form of efficient modifications of the transmitted or received signals based on prior knowledge of the signal format itself. For example, reduction in dispersion penalties are observed using pre-chirp [53,54] or electronic dispersion compensation [55][56][57], whilst non-linear penalties may be lowered by reducing phase noise (or timing jitter) by modulating the received signal with a phase proportional to the received intensity [58][59][60]. For multi-level formats, these techniques may also be applied predicatively at the transmitter [61].…”

Abstract-We 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. We confirm the widely held belief that the reported capacities are approaching the fundamental limits imposed by signal-to-noise ratio and the distributed non-linearity of conventional optical fibres, resulting in the reduction in the growth rate of communication capacity. We also discuss the techniques which are promising to increase and/or approach the information capacity limit.
