Abstract

In this paper, we analyze the performance of the single channel transmission system for different lengths of fiber using dispersion compensated fiber (DCF) and fiber Bragg grating (FBG). A system with high data rate of 40 Gbps is simulated and analyzed to study effects of factors like dispersion and nonlinearity for different modulation techniques. The analysis is done in terms of bit error rate (BER) and quality factor (Q) for a comparative study of different level coding. The simulation results depict that FBG works as a better dispersion compensator as compared to DCF, also provides improved performance in optical fiber network with symmetrical compensation. The observation results that duo-binary coding schemes depict good performance with FBG (Fiber brag Grating) up to a length of 4000 km.
