Development of a simulator of the effects of chromatic dispersion in optical fiber transmission

This thesis presents the development of a numerical simulator designed to investigate the effects of chromatic dispersion on signal propagation in optical fiber. After a brief introduction to fiber optic communication and the mathematical foundations of Group Velocity Dispersion (GVD), the simulator's architecture and its support for various signal types, including Gaussian and Nyquist pulses, are discussed. Through comparative analysis of temporal and spectral data, the impact of varying dispersion parameters and fiber lengths on pulse broadening and peak power degradation is evaluated. A series of test cases is presented in order to highlight the simulator's ability to model severe signal distortion in high-speed transmission, as well as the importance of dispersion management in modern optical networks.
