Comparison of Chirped Interference Influence on Propagation Gaussian and Super Gaussian Pulse along the Optical Fiber

Abstract

Basic task of all telecommunication systems is that signal propagation from transmiter to receiver should be as good as possible. There are many factors, in optical telecommunication systems, which disable such transmission. Dispersion is one of them. Optical fiber can work under normal or anomalous dispersive regime, but anomalous dispersive regime is better for signal propagation. It is the reason why we study Gaussian and Super Gaussian signal propagation along such fiber. Influence of inband interference, which appears at the beginning of optical fiber, on transmission quality is also studied in this paper. Magnitude of that influence is shown by determing of pulse shape at the reciver, i.e. at the end of optical fiber. Nonlinear Schrodinger equation is solved to get pulse shape along optical fiber.
