A Determination of Optical Fibers Types on the Spectrum Profile of the Mandelstam - Brillouin Scatter

The investigation deals with the type classification of optical fiber on the reflectogram obtained by the Brillouin reflectometer. The program for determination of optical fiber type by the Brillouin reflectogram is presented. The values of Brillouin frequency shift for some optical fiber types are given. The possibility to classify optical fibers on types and manufacturers using reflectogram is of practical interest. The work was performed with the financial support of the Ministry of Education and Science of the Russian Federation within the scope of the base part of a State Assignment within the sphere of scientific activity (Project No. 8.9334.2017/8.9).
