Paper Abstract

We develop a perturbation theory to analytically calculate effects of interchannel collisions on Gaussian pulses in a wavelength-division-multiplexed system with strong dispersion management. We show that, for complete collisions, the collision-induced frequency shift of a Gaussian pulse is negligible, while for incomplete collisions, this shift is significant. We also show that, as the dispersion management strength increases, the collision- induced position shift becomes more important than the frequency shift. An interesting result of our analysis is that the collision-induced frequency and position shifts depend on the dispersion management strength and the path- average dispersion, but not on the lengths of the two opposite-dispersion fiber segments in the dispersion map. We check the analytical predictions against direct PDE simulations, finding satisfactory agreement between them. We also give an estimate of the limit imposed on the transmission distance by such collisions.
