Advances in Modeling and Mitigation of Nonlinear Effects in Uncompensated Coherent Optical Transmission Systems

摘要

Recent results on analytical modeling of non-linear interference due to signal propagation in multi-span optical systems are reviewed, including high-symbol rate and ultra-wideband scenarios. Latest advances in nonlinearity mitigation, based on the use of machine learning techniques and nonlinearity tolerant modulation formats, are also discussed.
