A classification of the factors causing the change of the optical fiber strain by using the Brillouin reflectograms is considered. The differences of Brillouin reflectograms with strain along the optical waveguide are discussed under various impacts: temperature and mechanical longitudinal stretching. Reference Brillouin reflectograms for different kinds of optical fibers from the database are capable of improving a process of classification of potentially hazardous sections (sections of optical fibers with high mechanical strain or changed temperature) in the optical fiber. The results presented in this paper allow us on the basis of the analysis of Brillouin multi-reflectograms to identify a factor that has a predominant impact on the fiber strain in the investigated sections of the optical fibers in fiber optical communication lines.
