Interaction of Solitons in a Dispersion Managed Optical Communication System with Asymmetric Dispersion Map

Abstract

Interaction of optical pulses in a dispersion managed optical communication system with asymmetric dispersion map has been investigated in this paper. The well known variational formulation has been employed to obtain several ordinary differential equations for various pulse parameters, and then the equations have been solved numerically to identify launching criterion in the first cell of the dispersion managed system. To investigate the effect of the ratio of anomalous fiber section length to the total map length on the pulse collision dynamics, the nonlinear Schrödinger equation has been solved numerically. It has been found that, optimum system performance is achievable when the aforesaid ratio is approximately 0.7. With this ratio an improvement of approximately 25% in collision length has been predicted.
