چکیده مقاله:
Dispersion can be considered as one of the basic causes of function limitations in optical transmission, in which the phase velocity of a wave depends on its frequency and in this research proposed by simulate of controlling method. Due to the geometry nature of waveguides as an opticalfiber, they are highly dispersive for optical frequencies widely used in modern telecommunications systems. Because of chromatic/material dispersion among other phenomena as well as group velocity, waveguide and modal dispersion, the rate of data transmission on a single fiber is limited to pulsebroadening. Hence, in this paper we introduce the Chirp Fiber Bragg Grating and dispersion compensation fibers (DCFs) as key components which are used in symmetrical compensation method for compensating the dispersion in WDM system. By simulating transmission system we can propose the best numerical quantity of parameters for optimum outputs and its effect on improving gained information in the receiver that compare by different compensation components
