The propagation of solitons through an optical fiber with dual‐power law nonlinearity, in presence of stochastic perturbation term, is studied in this paper. The Langevin equations are derived. It is thus proved that solitons travel down an optical fiber with a fixed mean free velocity. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
