There are number of problems associated with the propagation of information through optical fibers. A pulse propagation model is essential to investigate the effects in nonlinear optical fiber communication. In this paper we used Symmetric Split-step Fourier method to solve the nonlinear Schrödinger equation (NLSE) which describes the pulse propagation model in optical fiber. We reported some simulation results such as variation in the soliton amplitude and pulse broadening of linear and nonlinear hyperbolic secant pulse due to dispersion. We also reported how the nonlinearity of soliton pulse compensates for these effects due to the dispersion. Finally the dispersion managed solitons are considered which are proved to be more robust to pulse broadening than conventional solitons.
