| Abstract: | In this paper, the influences of multi-perturbations originating from amplifier spontaneous-emission (ASE) noise and cross-phase modulation (XPM) in wavelength-division-multiplexed (WDM) are simultaneously considered by using the variational method to analyze evolvement characteristics of dispersion-managed soliton transmission. Simple analytical expressions for dynamics equations of dispersion-managed soliton and timing jitter are obtained. At last, the degrees of effect to system for three perturbations are given. |
