Research Characteristics of Mandelstam - Brillouin Scatter Spectrum in the Polarization Maintaining Fibers

Results of experimental researches of characteristics of the Mandelstam - Brillouin scatter spectrum in the polarization maintaining single-mode fibers are presented in this work. Reflectograms obtained by BOTDR are given. Analysis of the experiment results revealed significant dependence differences of the polarization maintaining fibers from the same dependences of others optical fiber types. 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).
