Resonant intrachannel pulse interactions in dispersion-managedtransmission systems

摘要

Nonlinear intrachannel interactions in a transmission system withnstrong periodic dispersion management are investigated. An analyticalnmodel that describes the fluctuation of the temporal position andnamplitude of the main signal and ghost pulse generation at zero bits duento intrachannel crosstalk is developed. Intrachannel nonlinear effectsnare found to be a resonant process which is induced by periodic forcingndue to lumped amplification assisted by temporal phase matching.nExplicit formulae to estimate transmission impairments such as timingnand amplitude jitter are provided based on the analytical model. Thenrole of distributed amplification to suppress intrachannel nonlinearneffects is also discussed. A more fundamental analytical framework whichnenables one to evaluate intrachannel crosstalk over a wide regime ofnsystem configurations is also presented
