EFFECTS OF FIBER NONLINEARITIES ON OPTICAL COMMUNICATION

This paper focuses on the recent research in optical communications and the effects of fiber non linearities in optical communication. Moreover, this paper covers the investigation on characteristics of optical fiber, modelling/analysis of fiber nonlinearities and laser effect on optical fiber in the literature. This paper also provides the information about the parameters, methodology and materials used in optical fiber. Here, most commonly used material is fiber laser and its advantages are increased output power, peak power and optical quality. This paper further describes several types of nonlinearity effects on the basi s of various methodologies such as dual parallel Mach ? Zehnder modulator (DP - MZM), fiber optical parametric amplifiers (FOPA), Darboux transformation (DT) and scalar finite element method (SC - FEM) and many parameters are also discussed. Their applications a re also discussed and relative study of these effects is presented. The primary purpose of this paper is to understand the effects of nonlinearities, and to encourage further research in this area.
