The urgency of the problem of monitoring the state of fiber optic lines in conditions of temperature-deformation effects is considered. The influence of the optical sensor calibration error and instrumental error on the accuracy of temperature and deformation determination is simulated. A new method of post-processing the reflected Brillouin optical spectrum which makes it possible to obtain more accurate values of temperature or strain in the optics is demonstrated. The results of simulation and experiment showed the reliability of the proposed solutions for simultaneous control of temperature and deformation of an fiber optic cable.
