description: In the course of the work, the principles and operation of the backbone fiber-optic communication lines of Â«Gazprom Transgaz St. PetersburgÂ» were studied. I mastered the method of reflectometric measurements of fiber-optic lines and learned how to process the results obtained (reflectograms). With the help of the JDSU MTS-6000 reflectometer, measurements were carried out on two sections of the Â«Gazprom Transgaz St. PetersburgÂ» main lines "Bronevaya-Kolpino" and "Bronevaya-Varshavskaya". In the Fiber trace program, I analyzed the reflectograms obtained in these areas and compiled a protocol with the measurement results. Compared the results obtained with the results of previous years and assessed the evolution of degradation of these fiber-optic lines. As a result, we can conclude that the "Bronevaya-Varshavskaya" line is fully operational, the "Bronevaya-Kolpino" section 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 company's employees in analyzing the evolution of degradation of fiber-optic communication lines of Â«Gazprom Transgaz St. PetersburgÂ».
