Abstract

In this paper, the nonlinear Schrödinger equation is solved (Equation core optical fiber data transmission) with regard to fiber loss and gain and it will show that using intermittent reinforcement amplifiers and soliton pulse can be input from a broad concentration. We also show the two properties of non-normal dispersion and nonlinear effects under certain conditions that they can neutralize each other's effect (Both of which are factors that are destructive to them and are a limiting factor for optical telecommunications) and can make a balance between these two properties with the lowest error rate of data transfer.

Keywords: Nonlinear Schrödinger equation, the abnormal dispersion, nonlinear effects, soliton waves
