Non -Linearities of optical fiber affecting modern communication system: An Overview
In recent years, even after the installation of erbium doped fiber amplifier which has a higher bit rate transmission usually suited for transoceanic communication, but people’s demand for higher data transmission capacity is unprecedented and growing continuously. The paper is presented in the form of overview addressing all the non-linear effects encountered in fiber, and what are the advantages and disadvantages it will have on the optical telecommunication. Topics covered are the types of non-linear effect occur under non-linear scattering and changes in refractive index whenever the beam interacts with various components inside the optical fiber.
