Abstract: The phenomenon of broadening of pulse as it travel along the optical fiber called dispersion, is the main barrier in achieving an efficient and high speed communication system. In this paper, we have analyzed the effect of fiber length (km), input power (dBm) and attenuation coefficient (dB/km) on the overall performance of an optical communication system containing Fiber Bragg Grating (FBG) as the dispersion compensator. The values of system performance parameters like Quality factor, Output power (dBm), Gain (dB), Noise figure (dB) and Minimum bit error rate (BER) have been calculated and analyzed using Eye diagram and related tables and graphs. All the simulation of the system has been done on the Optisystem 14.0 software.

Keywords: Fiber Bragg Grating, Fiber Length, Input Power, Attenuation Coefficient, Quality Factor, Output Power, Gain, Noise Figure.
