Abstract

In this paper, a proposal for analyzing the performance of an optical system by using dispersion compensation fiber (DCF) and linear chirped apodized fiber Bragg grating (FBG) has been put forth. Both systems have three different schemes pre, post and symmetrical. Various parameters used for this analysis are input power, distance & input bit rate. Performance is analyzed in terms of Q factor, Bit Error Rate (BER) and Eye Diagram. It is found that use of FBG as a dispersion compensating element gives better system performance as compared to DCF.

Keywords: Bit Error Rate (BER), Dispersion compensation fiber (DCF), Eye diagram, Linear chirped apodized fiber bragg grating (FBG), Pre compensation, Post compensation, Quality factor, Symmetrical compensation.
