Performance Analysis of Long-Distance WDM Dispersion-Managed Transmission System using Dispersion Compensating Fiber and FWM Effects on Optical Communication System

Abstract

ABSTRACT Telecommunication Network based on optical fiber technolgy have become a major information transmission system, with high capacity optical fiber links encircling the globe in both terrestial and undersea installations. In this dissertion fiber non-linearities have been studied, and analyzed the effect of various parameters of received power. The non-linearity in optical fibers fall into two categories: one is stimulated scattering (Raman and Brillouin), and the other is the optical Kerr effect due to changes in the refractive index i.e. self phase modulation, cross phase modulation and four wave mixing. The optical transmission is immune to electromagnetic interference and other environmental factors. In contrast the copper wire system and microwave links face a great reduction in transmission data due to these factors. In the standard single mode fibers, the polarization mode dispersion is the phenomenon that cause the hurdles to reach the high bit-rate-distance product of amplified lightwave system. Non linearity effects arose as optical fiber data rates, transmission lengths, number of wavelengths, and optical power levels increased. Although fiber optics system excel in high bandwidth applications, optical fiber has been slow to achieve its goal to the premises or to solve the last mile problem. However, as bandwidth increases, more and more progress towards this goal can be observed.
