A comparative study of different dispersion compensation techniques in long haul communication

Optical fiber communication (OFC) provides us a very high bit rate data communication. There are different types of impairments and signal degradation mechanisms involved with this high speed communication system. In case of long haul communication, the most effective impairment is dispersion. It affects the signal very badly when signal travels a long distance. Different techniques are available to compensate dispersion. Not all of them are the same in performance. In this work, we study multiple dispersion compensation techniques and their performance measures and compare them with respect to the BER, Q-factor, Eye height, threshold etc. For this purpose, we used OptiSystem13 simulation software. Based on our analyses, we derive a conclusion on which technique is better for high speed long haul OFC networks.
