description: The object of research is the main fiber-optic communication line (hereinafter referred to as FOCL) of Gazprom transgaz Saint-Petersburg LLC. The purpose of the work is to develop options for complex analysis of measured reflectometric data on the section of the main fiber-optic communication line of âGazprom transgaz Saint-Petersburgâ. Within the framework of preparation for writing the thesis the provided materials were studied, such as normative documentation in the field of operation of fiber-optic communication lines, production reports on carrying out planned and preventive works and protocols of OTDR measurements. The principle of operation of optical reflectometer MTS-8000 and software product for processing of OTDR measurements and analysis - âFiber Traceâ were also studied. During the writing of the thesis, using the software product âFiber Traceâ were analyzed the received OTDRs from the site âKS Portovaya - URS Gvardeyskayaâ. The protocols with the results of measurements were made. Comparative analysis of the obtained results with the results of previous years was performed. A variant of complex analysis was developed, which includes the analysis of integral losses and internal losses inside the fiber. According to the results of the complex analysis it was revealed that the section of the main fiber optic fiber optic line âKS Portovaya - URS Gvardeyskayaâ is serviceable and suitable for operation. Only at optical fiber (hereinafter referred to as OV) â15-â39 from 2020 the growth of integral and internal losses is observed. The obtained data and method will be further used by the companys employees to analyze the evolution of degradation of Gazprom transgaz Saint-Petersburgs fiber-optic communication lines.Â
