When the polarization of the two different wavelengths of light in fiber optic transmission,due to cross-phase modulation and dispersion of fiber in common,may lead to cross-phase modulation instability generated,The phenomenon in the optical switch,ultra-generated continuous spectrum of the areas have important applications,but also affect system performance WDM an important factor.In this paper,the light from the double-fiber coupling Nonlinear Schrodinger equation,linear analysis of stability derived cross-phase modulation instability of the dispersion and gain spectrum.Simulation of the gain spectrum with the dispersion parameters,non-linear parameters and power changes.The results showed that the pulse peak strength with the increase in power has changed,peaks and the wide spectrum are growing.In other conditions remain unchanged,and the dispersion of the parameters of increasing cases,the wide spectrum narrows,and peaks unchanged.Secondly,in the other conditions remain unchanged,non-linear parameters of increasing the circumstances,the wide spectrum of larger,bigger peaks.
