Investigation of the influence of climatic conditions on the accuracy of acousto-optic trace route localization methods for all-dielectric optic cables

Abstract

Abstract In the conditions of long-term operation of cable communication lines, the problem of timely maintenance of cable communication lines becomes relevant. Maintenance at minimum cost and maximum efficiency requires precise cable tracing methods. The paper considers the results of evaluating the effectiveness of acousto-optical methods for searching for the route of laying an all-dielectric optical cable laid in a package of microtubes underground. Amplitude and phase algorithms for localizing the route of laying an all-dielectric cable are considered. The results of measurements of the parameters of a distributed acoustic sensor on a test site in various climatic conditions are investigated.
