Simulation of fiber-optics signal transmission using split-step Fourier method
Abstract
– In this paper, we investigate the principle of optical signal transmissions in the optical fiber. By applying a numerical method, namely split-step Fourier method, we simulate the optical communication system and show the algorithm to solve the optical pulse propagation in the optic fiber. Next, by using MatLab-based program, we evaluate the system performance by investigating different parameters such as loss, dispersion, nonlinearity in the optic fiber and bandwidth, transmission distance, launch power. Hence, we can evaluate the influence of the effect of pulse broadening caused by dispersion, ASE noise by EDFA amplifiers, nonlinearity on system performance. Model, detailed algorithm, and achieved results could be used effectively, flexibly to simulate optical pulse propagation.
