Abstract. This paper recovers single and straddled optical solitons for the concatenation model in the presence of multiplicative white noise by using an improved modified extended tanh function approach. The parameter constraints for the existence and sustainment of such solitons are also presented. It is observed that the effect of white noise is confined to the phase component of the recovered solitons.
Keywords: straddled optical solitons, integrability, concatenation model.
