چکیده
AbstractIn this paper we will study the various method of dispersion compensation in single mode fiber created because of dependence of group index to wavelength known as chromatic dispersion. Various methods of dispersion compensation are Dispersion compensation fiber (DCF) which compensates dispersion at 1310nm and 1550 nm and Fiber Bragg gratings (FBG) which compensate dispersion at wavelength around 1550nm. Also we will study the comparison between the two. DCF techniques increases the total losses non-linear effects and costs of optical transmission system. FBG helps in decreasing the cost of the system and also have low insertion loss.

Design and performance evaluation of a dispersion compensation unit using several chirping functions in a tanh apodized FBG and comparison with dispersion compensation fiber.
In this work, various dispersion compensation methods are designed and evaluated to search for a cost-effective technique with remarkable dispersion compensation and a good pulse shape. The techniques consist of different chirp functions applied to a tanh fiber Bragg grating (FBG), a dispersion compensation fiber (DCF), and a DCF merged with an optimized linearly chirped tanh FBG (joint techniq...
