Abstract The apodization function has targeted a significant impact in the state of the art of group delay, dispersion compensation, and acceptable decreasing of side lobes in the spectrum of FBG reflection. Accordingly, Bragg grating length would be considered as the backbone parameter in order to achieve a distinguishable performance. Here, the utilization influence of the presence of Fiber Bragg Grating (FBG) as a dispersion compensator. In addition, we have implemented a tuned uniform- Apodized FBG methodology according to various apodization functions. A Common apodization functions have been studied and tested effectively. Experimental results show that the proposed raised cosine Apodized function has scored the highest reflectivity with 50% reduction in the side lobes level and the narrowest bandwidth among all tested functions. Moreover, Simulations for this function were performed with various lengths of grating. It is demonstrated that the reflection spectrum value is fixed at 100% at grating lengths greater than or equal 28 mm and the minimum dispersion value is realized. An erbium-doped fiber amplifier (EDFA) was used to compensate for the power loss as a result of the attenuation in the optical communication network. Its performance was evaluated based on various parameters such as eye aperture, power spectrum, and energy intake before and after its use. It was observed that EDFA gives better performance with better eye opening when compared to other types of amplifiers. |
