Dispersion Compensation Techniques:A Review
Dispersion compensation plays a very significant role in controlling the overall chromatic dispersion of a system. It is used to avoid excessive temporal broadening of ultra-short pulses or the distortion of signals. Without dispersion compensation, each symbol gets broadened so much that it would strongly overlap with a number of neighbored symbols. Dispersion bound the bandwidth or information carrying capacity of a fiber. The dispersion compensation techniques discussed in this paper are Dispersion compensating fiber (DCF), Electronic dispersion compensation (EDC), Fiber Bragg grating (FBG), Digital filters.
