ABSTRACT : In this paper I studied higher order dispersion (β3) effects on soliton propagation in dispersion shifted fiber (DSF) with solving numerically the Nonlinear Schrödinger Equation (NLSE). Initial pulse have hyperbolic-secant shape and power that give a fundamental soliton, fiber loss is compensated by pre-emphasis method. I used Symmetrized Split Step Fourier (SSSF) method to solve the NLSE and compare soliton propagation in DSF from result of NLSE with β3 is included and β3 is negligible by measure root mean square (rms) pulse width of soliton that determines the bit rate of soliton communication systems.
