Theoretical and Experimental Study of Soliton Trans- mission in Dispersion Managed Links

摘要

The propagation of solitons in a dispersion managed link can be mainly modeled with the evolution of two parameters γ and C, related to the spectral width and the chirp. Steady propagations are shown to be possible if the average dispersion lies in the anomalous domain. With the same condi- tions, periodical propagations are both theoretically and experi- mentally demonstrated. With the help of a perturbation theory, the jitter and the signal to noise ratio are theoretically evaluated. The latter is experimentally shown to be the low power limit of terrestrial systems base on non dispersion shifted fiber.
