Experiment Calculation of Optical Fiber Dispersion Compensation

Abstract

The intended application of our Dispersions in an optical fiber.  Dispersion is the spreading of light pulse as its travels down the length of an optical fiber. Dispersion limits the bandwidth or information carrying capacity of a fiber. in this paper we try to use a new system built by software optics version 7.to understand the effect of dispersion compensation FBG in fiber optics using CW laser as a power source with frequency 193.1 THz, 0 dBm, NRZ pulse generator by the help of ideal desperation compensation at 193.1 THz frequency, Bandwidth 1 THz and dispersion equal to -2000 ps/nm, with one loop amplification system. At the receiver a PIN photodiode at dark current 10 nA is used. Finally we can get the results that will be measured by Eye diagram device corresponding to the fiber lengths.
