Fiber dispersion compensation in single side band optical communication system using ideal fiber Bragg grating and chirped fiber Bragg grating without DCF

Abstract

In this paper, a 10 Gbps, single side band optical communication system is implemented with different dispersion compensation schemes. This paper proposes that dispersion compensation is fruitful with a linear chirped fiber Bragg grating, without a dispersion compensation fiber at higher input powers. Its performance is compared with fiber Bragg grating and DCF. Same global parameters are used for all simulations. The simulated transmission system has been analyzed by different performance parameters like Q factor, output RF power and eye diagram extinction ratio. The Q factor, output RF power and extinction ratio can be improved about by 21 dB, 3.5 dB, and 20 dB respectively. The simulations are conducted for higher input power from 0 dBm to 8 dBm and for fiber length from 20 km to 80 km. The BER in CFBG is 15 dB lesser than FBG. The CFBG shows better performance than conventional FBG. The signal delay is also the lowest in the method using CFBG. The Q factor and signal delay are also compared with CFBG, FBG, DCF and uncompensated system.
