Abstract
The main objective of this project is to analyze nonlinear effects in optical fiber and to discuss how these effects cause dispersion in input signals. This project also discusses the pros and cons of nonlinear dispersion. Nonlinear dispersion may be advantageous in improving the performance of an input signal at the receiver side but may be disadvantageous in restricting the transmission rate through an optical system. The nonlinear effects were simulated with the OPTSIM tool and analyzed using the eye pattern method with respect to bit error rate and Q factor. Simulation results of the OPTSIM tool were also compared with the numerical analysis of nonlinear effects using non-linear Schrödinger equation, which is coded and simulated in MATLAB
