Fiber-optic communication lines (FOCL) have several unique advantages over existing alternative methods of information transmission. For most enterprises, FOCL is the most effective solution. Gas industry enterprises were no exception. Due to the high risks of emergencies at the facilities of these enterprises, it is necessary to provide reliable, fire and explosion-proof, protected communication lines. FOCLs have all the above advantages. To ensure the uninterrupted operation of fiber-optic communication lines, it is necessary to take into account the features of these lines, possible problems arising at the stage of construction and operation of fiber-optic communication lines, features of defects that may arise during the installation and operation of fiber-optic communication lines. This work is devoted to the study of the features of fiber-optic communication lines and the causes of losses on these communication lines. Particular attention is paid to the features of the defects on the FOCL. A literature review of the features of FOCLs, their defects, the effects of defects on the parameters of the line has been carried out. The work investigates the operating main FOCL. The change in its parameters over a 6-year period of operation is analyzed. The results obtained are presented and conclusions are formulated. |
