This article deals with the problem of crosstalk that appears as a result of multiple reflections of a single pulse in an array of fiber Bragg gratings. A computer model of crosstalk for a particular design of information-measuring fiber-optical device based on the Bragg grating is created. Developed computer model makes it possible to calculate power, phase, and the routes of all impulses arriving to detector and demodulation section. Calculation of the crosstalk influence level to the interference signals is done on the base of the designed model, and recommendations for the reflection coefficients of fiber Bragg gratings in the array are worked out.
