This paper presents a comprehensive study of the Gaussian Apodized Fiber Bragg Grating (GA-FBG) as a stand-alone dispersion compensator for a 150 km long optical link. The main objective of this study is to investigate the performance of GA-FBG in various compensation modes and determine the maximum transmission distance it can support as a solo dispersion compensation unit. To achieve a more cost-effective optical link, we use the GA-FBG implementation as a substitute for the expensive Dispersion-Compensating Fiber in the network. To optimize the performance, the study explores three different compensation modes and analyses the grating parameters of the GA-FBG, taking into consideration all practical limitations of a fiber Bragg grating (FBG) in the design. The optimized links are assessed based on their performance characteristics using a Bit Error Rate analyzer. After optimizing the GA-FBG and the channel parameters of the link, the results demonstrate that the GA-FBG exhibits excellent dispersion compensation capabilities. The symmetrical compensation mode yields a remarkable Q-factor value, enabling transmission distances beyond 500 km with ease. Finally, to validate the functionality of the proposed system, we use the OptiSystem software. Our findings demonstrate that the GA-FBG can effectively compensate for dispersion, achieving a more cost-effective and efficient optical link with great potential for long-distance transmission.
