Position Effect and Number of Fiber Bragg Grating FBG in a High Optimized Optical Link

This paper discuss the optimal use Fiber Bragg Grating FBG as dispersion compensator. The simulated models of optical transmission system have been analyzed in term of eye diagram and Q factor using OptiSystem simulator. Three models of optical link are proposed in this work in order to optimize the use of the FBG’s in the way of dispersion compensation. A comparative study has been realized between the models proposed in this work. The output reading results show that the use of the FBG to compensate the chromatic dispersion stays a good idea. Several uses of the FBG’s are done in this work. The proposed model based on the use of two FBG’s separated with a Single Mode Fiber SMF presents the good performance of the system. The results reading using the double pre-compensation revealed itself to a better performance of the new system proposed.
