Dispersion is a serious issue related to the integrity of data transmission in high-speed optical fibercommunication systems. Fiber Bragg gratings (FBGs) are among the most important componentsused to reduce dispersion in these systems. FBGs are simple, and have low-cost filter for wavelengthselection, low insertion loss and customized reflection spectrum, and wide bandwidth. This studyinvestigates the optical transmission system performance of a symmetric FBG for dispersioncompensation. Transmission scheme simulation is analyzed with different parameters based on anOptiSystem simulator. Symmetric FBG and avalanche photodetector are used to enhance theevaluation of an optical transmission system. Optical fiber length, attenuation coefficient, inputpower, bit rate, and FBG grating length parameters are also investigated in detail to determinesystem optimization. The developed simulation design demonstrated high gain, low noise figure,substantial output power, and high Q-Factor for long transmission distance of up to 60 km with 0.2dB/km attenuation coefficient.
