In this work we present combined chromatic dispersion compensation methods for fiber optical transmission systems. Chromatic dispersion (CD) compensation is very important premise to significantly improve performance of fiber optical transmission systems (FOTS) and increase maximum data rate and transmission distance.Dispersion compensation methods like dispersion compensating fiber (DCF), fiber Bragg grating (FBG) and optical phase conjugator (OPC) were used together. The performance of realized FOTS without CD compensation was very poor, but it has been shown that using combined compensation methods (FBG-DCF, FBG-OPC, and OPC-DCF) system's performance can be improved greatly. The best results were obtained by using combined FBG-OPC dispersion compensation method which showed the best BER value.
