| Abstract: | Starting from the nonlinear Schr-dinger (NLS) equation expressing the dispersion management solitons (DMS) transmission, the evolution properties of the DMS are studied by making use of symmetrical slit-step Fourier numerical method. It is shown that the interaction of the optical solitons is decreased when the solitons are transmitting in the fiber managed opposite dispersion coefficient periodically, which the transmission properties of the solitons are improved greatly. And then, the merits and significance of DMS are pointed out in the practical communication systems. |
