Abstract

Abstract

Optical fiber communication (OFC) provides high bit rate data communication. There are various types of impairments and signal degradation mechanisms which are involved with this highspeed communication system. In case of long distance communication, the most prominent impairment is dispersion. Dispersion affects the information signal very badly when it travels along a long distance. There are different techniques available to compensate dispersion. In this paper, the various methods of dispersion compensation in single mode fiber created because of dependence of group index to wavelength known as chromatic dispersion are being discussed. Various methods of dispersion compensation are dispersion compensation fiber (DCF) which compensates dispersion at 1310 and 1550 nm and Fiber Bragg gratings (FBG) which compensate dispersion at wavelength around 1550 nm. These techniques and their performance measures are being compared with respect to the BER, Q-factor, eye height, threshold etc. DCF technique increases the total losses because of non-linear effects and cost of the optical transmission system while FBG decreases the cost of the system and has low insertion loss as well. Based on the simulation results, it has been concluded that which technique is better for high speed long haul OFC networks.
