Abstract

Problem statement: The performance of the optical network is highly dependent to Chromatic Dispersion (CD). CD has been a big issue when higher bitrate or longer distance is desired. Many methods have been represented to mitigate or eliminate this phenomenon. A wide range of optical and electrical compensation has been investigated. Approach: In this study we evaluate the efficiency of the electrical pulse shapes including (NRZ,RZ and Triangular form) in electrical compensation with Feed Forward-Decision Feedback Equalizer (FFE-DFE) technique and optical compensation; Dispersion Compensation Fiber. Results: It was compared the mentioned situation with Quality factor versus increasing the distance with different pulse shapes. It was observed that in Electrical compensation there is no considerable with different pulse shapes while in optical compensation NRZ is definitely more susceptible than others. Optical and electrical compensators were compared regarding to jitter and optical compensator showed much better performance. Conclusion: chromatic compensation was implemented with different pulse shapes and RZ pulse shape with optical compensation showed best performance.
