Abstract :
We have evaluated the chromatic dispersion compensation for a long-haul WDM transmission. A 4 channel optical network was modeled, simulated and analyzed at a 600 km distance using two chromatic dispersion compensators i.e. fiber Bragg grating (FBG) and dispersion compensated fiber (DCF). Subsequently the modulation scheme and also the traffic load are varied to determine the robustness of the compensators to sustain the changes imposed on the lightwave optical system. This analysis concludes that the grating device seems to be the better compensating solution for the long haul narrowband transmission. In addition, the FBG is also able to sustain the changes in traffic load and modulation scheme much better than the DCF
