Mitigation and Comparison of Chromatic Dispersion at Distinct Frequencies Using Hybrid Model at A Bit Rate of 100Gbps over 120Km Distance

In this paper, a Hybrid model is proposed for compensation of chromatic dispersion which can ensure the high bit rate, a higher Q-factor and lower BER for long distance optical communication. It can be achieved by taking into consideration the major limiting factors like dispersion, attenuation, and other linear and non-linear effects of optical fiber. Chromatic dispersion is the principal deterrents in high velocity information transmission thus ought to be compensated by different methodologies all through the transmission system. This study presents the simulation results of a proposed hybrid model which is a combination of Uniform Fiber Bragg Grating (UFBG) and Electronic Dispersion Compensation (EDC) along with Erbium Doped Fiber Amplifier (EDFA). This model is designed to mitigate the effect of chromatic dispersion present in optical fiber communication system. Here, the analysis is carried out by varying the input carrier frequency range from 193.1 THz to 193.5 THz and then comparing their outcomes to get the satisfactory result. As a result, we find that the quality factor rises monotonically as the frequency is increased up to some level and then it undergoes an abrupt fall along with a rise in BER. The simulation is done with the help of Opti-System 7.0 simulator.
