Abstract :
Nonlinear intrachannel interactions in a transmission system with strong periodic dispersion management are investigated. An analytical model that describes the fluctuation of the temporal position and amplitude of the main signal and ghost pulse generation at zero bits due to intrachannel crosstalk is developed. Intrachannel nonlinear effects are found to be a resonant process which is induced by periodic forcing due to lumped amplification assisted by temporal phase matching. Explicit formulae to estimate transmission impairments such as timing and amplitude jitter are provided based on the analytical model. The role of distributed amplification to suppress intrachannel nonlinear effects is also discussed. A more fundamental analytical framework which enables one to evaluate intrachannel crosstalk over a wide regime of system configurations is also presented
