description: In preparation for the thesis, the principle of operation of the JDSU MTS-6000 optical reflectometer and the software product for processing reflectometric measurements, analysis and certification "Fiber Trace" was studied. During the thesis, the JDSU MTS-6000 reflectometer carried out measurements on two sections of the main lines of Gazprom Transgaz St. Petersburg LLC "Port LPUMG- URS "Guardeyskaya" and "CS Portovaya-URS "Guardeyskaya". The Fiber trace program analyzes the reflectograms obtained in these areas and draws up a protocol with the measurement results. A comparative analysis of the results obtained with the results of previous years is performed and the evolution of degradation of these fiber-optic lines is estimated. According to the results of the conducted research, it was revealed that the section of the Port LPUMG- URS "Gvardeyskaya" is serviceable and suitable for operation. The section "CS Portovaya-URS "Gvardeyskaya"" has defects exceeding the permissible values of losses in several couplings, but the value of kilometer attenuation does not exceed the established 0.22 dB/km. The data obtained will be further used by the companys employees in analyzing the evolution of degradation of fiber-optic communication lines of Gazprom Transgaz St. Petersburg LLC.
