The given work is devoted to measure the chromatic dispersion of a single-mode optical fiber in a microwave photonic transmission line using a vector circuit analyzer. In accordance with the set goal the following tasks were solved: 1. Study of the current state of the art of optical fiber dispersion measurement methods. Selection of the method. 2. Analysis of signal conversion in microwave photonic transmission line taking into account the dispersion of single-mode fiber and nonlinear effects. 3. Computer modeling of signal conversion in microwave photonic transmission line in OptiSystem software environment. 4. Experimental studies of the microwave photonic transmission line and comparative analysis of the results of theoretical calculations, simulation results and measurements. The obtained results show the effectiveness of the proposed method of chromatic dispersion measurement. The results of theoretical calculations of chromatic dispersion obtained in mathematical software packages (MATLAB, Mathcad), the results of modeling in the OptiSystem software environment and the data of our experimental measurements are in good agreement. The proposed method of measuring the chromatic dispersion of optical fiber can be used for microwave photonic signal transmission lines up to 2000 meters long.
