摘要：
This work obtains mean free velocity of bright optical solitons in optical fibers that are studied with quadratic-cubic form of nonlinear refractive index. The perturbation terms are from multi-photon absorption, filters and stochastic effect. The Langevin equation is derived from soliton perturbation which lead to the mean free velocity of the soliton.
