Perturbed higher order nonlinear Schrdinger equation describing the propagation of femetosecond optical pulse in the optical fiber under the perturbation of continuous wave was presented.The interactions between bright optical soliton and continuous wave have been studied by moment method and perturbation theory.Also the numerical evolution by Runge-Kutta and split step Fourier method are given.As a conclusion,the injected continuous wave should be avoided at best since it was harmful to the optical soliton communication.
