Comparative investigation using fuzzy model and OptSim on WDM systems in presence of FWM and dispersion compensation

This paper, investigates the impact of pre-, post-, symmetrical using Dispersion Compensating Fiber (DCF) and Fiber Brag Grating (FBG) dispersion compensation methods on Four Wave Mixing (FWM) for 10 Gb/s non-return to zero (NRZ) links by varying the state of polarization and core effective area of fiber through computer simulation. Performance characteristics (FWM power, eye diagram and Q value at the output) are studied by simulating the optical communication systems. A fuzzy controller based on fuzzy rule base using Adaptive Neuro Fuzzy Inference System (ANFIS) has been reported. It is indicated that FBG technique has been found superior to all other methods.
