Performance Analysis of dispersion compensation using Fiber Bragg Grating (FBG) in Optical Communication

Abstract

This paper discussed on a simulation of optical transmission system in optical fiber. The optical fiber is always used in telecommunication system because of its characteristics which include small size or dimension, low loss and low interferences from outside environment. There are various types of optical fiber, the Fiber Bragg Grating (FBG) is commonly chosen as important components to compensate the dispersion in optical communication system. FBG is very simple, has low cost filter for wavelength selection and low insertion loss, it has also customized reflection spectrum and wide bandwidth. We have analyzed the dispersion compensation using Fiber Bragg Grating at different fiber lengths. The simulated transmission system have been analyzed on the basic of different parameters by using OptiSystem simulator, By simulating a model of communication system and using the most suitable settings of the system which include input power (dBm), fiber cable length (km), FBG Length (mm) and attenuation coefficient (dB/km) at cable section, four different parameters will be investigated which are output power (dbm), noise figure (dB), and gain (dB) Q-Factor (db) at receiver. We will see the help of eye diagrams in subsequent graph. All the results are analyzed using OPTISYSTEM simulation at 10 Giga bits per second (Gb/s) transmission systems.
