Abstract In this paper, the higher-order nonlinear Schrodinger equation (NLSE) represents description of the propagation of short light pulses in mono-mode optical fibers. The optical solitons and solitary wave solutions of higher-order nonlinear Schrodinger equation mono-mode optical fibers are organized by apply the modified simple equation method to get the exact solutions and possibility of given this solution graphically at a given moment. This solutions help the researchers to study the physical properties of this model and its applications. There are many different types of models that we find in applied science that can be solved by this effective and reliable method. This method can be effective and successful in solving and understanding many of the problems of higher-order non-linear in the various fields of research and advanced.
