Abstract :
Average soliton propagation in a periodically lumped amplifier system for a dispersion-allocated soliton transmission line with an average negative GVD over an average soliton period is studied by numerical simulation using the split-step Fourier transform. The results show that a bright optical soliton can propagate stably in a positive dispersion region as long as we guarantee a negative average dispersion value and the suitable peak amplitude A. This allows us to combine fibers with large positive and large negative dispersion to propagate solitons, which in turn will enable us to introduce solitons in a commercial system
