An Improved Methodology for Dispersion Compensation and Synchronization in Optical Fiber Communication Networks

We consider that Optical communication network offers very high potential bandwidth and flexibility In terms of high bit-rate transmission. However, their performance slows down due to some parameter like dispersion, attenuation, scattering and unsynchronized bit pattern. In long haul application, dispersion is the main parameter which needs to be compensated in order to provide high level of reliability of service (ROS). Fiber Braggs Grating (FBG) is one of the most widely used element to compensate it, however its performance slows down with the increase in distance. In this paper we proposed a method for dispersion compensation which offers much better performance than FBG compensation. This method offers almost negligible dispersion and very high value of synchronization by reducing jitter portion in the Eye diagram. This method also offers very high value of Q-factor, SNR and Reduced BER in long haul optical communication networks.
