Features of construction and operation technologies of fiber-optic cable lines for the oil-pipe structure of Western Siberia

In this paper considers the main features and problems of installation and operation of fiber-optic cable links of the oil-transmission structures of Western Siberia. Complex geological and climatic conditions, as well as the specifics of the construction of the pipeline system, could not but affect the implementation of the installation of technological fiber-optic cable lines. Harsh natural conditions not only impose specific requirements on the technology, cable and cable fittings used, but also require special approaches in the implementation of sanitary norms and ensuring the greatest possible comfort of people. Complex geological conditions, lack of infrastructure, low temperature set the task of introducing new technologies for organizing the installation of fiber-optic communication lines for the subsequent achievement of the maximum possible lifetime of communication cables. The necessity to perform works under extreme conditions (low negative temperature and high wind speed at the work at height on supports) leads to stricter requirements for all components of the technological process: specific requirements are imposed on machinery and equipment, the requirements for cables and the requirements for cable fittings are increased, the tolerances for the execution of technological operations are toughened, the role of the human factor is significantly increased and the price of error is significantly increased. All this has determined the special role of quality control. In the paper shows that one of the main problems of the employment of fiber-optic links in the extreme conditions of the North is the lack of relatively inexpensive field instruments for estimating the suitability of the optical cable. This does not allow to effectively control the quality of the work in conditions where the probability of error is high. Such measuring instruments can be implemented on the basis of BOTDR or POTDR. In both cases, development of an inexpensive field device is required. But POTDR potentially allows you to create a more versatile device.
