Abstract— We studied higher order dispersion (β3) effects on soliton interaction in dispersion shifted fiber (DSF) with solving numerically the Nonlinear Schrödinger Equation (NLSE). Soliton interaction in the fiber determines the bit rate transmission distance product of communication systems. We used a soliton pair that has secant hyperbolic profile as input to the NLSE to analyze soliton interaction. Initial soliton power given a fundamental soliton and fiber loss is negligible. We used Symmetrized Split Step Fourier (SSSF) method to solve the NLSE . We compare soliton interaction in DSF from result of NLSE with β3 is included and β3 is negligible. And we find optimum value of parameter soliton pair so can obtain the maximum bit rate transmission distance product.
