The advent of fiber optics has revolutionized telecommunication systems around the world, enabling an unprecedented amount of information exchange, all at the speed of light. One of the keys to the success of the ensuing photonics revolution will be the use of optical solitons in fiber optic communication systems. Solitons are a special breed of optical pulses that can propagate through an optical fiber undistorted for tens of thousands of kilometers. A rapid progress during the 1990s has converted optical solitons into a practical candidate for modern light wave system. In this paper a brief overview of the development of non linear optics and optical solitons is provided. The nonlinear schrodinger equation has been solved under soliton condition, so that soliton propagation can be simulated.The numerical analysis of the nonlinear effect is done by NLSE. The equation is solved using split step algorithm,which is coded in Matlab. The results are displayed in the form of 3D pulse at regular intervals, phase charge and pulse broadening ratios are
