Control of optical cables condition installed using roadside technology

摘要

It is necessary to take into account that in the process of technical exploitation of transport multichannel communications (TMC) laid on the roadside, the components included in this system are subjected to mechanical, thermal and geophysical influences. In this case, damage to the TMC and the pinned optical cable is possible, the TMC leakage failure leads to the filling of the pipelines with water, mud, siltation in significant areas, which deprives the FOL of all advantages in the form of the possibility of additional laying or replacement of the FOL. Timely detection and elimination of leakage of TMC avoids adverse consequences and reduces the costs of the technical operation of the FOL. In practice, however, maintenance of TMC is often not carried out. and the condition of the pipelines is identified when performing work with the optical cables, which significantly reduces the reliability of the FOL operation. To improve the reliability of the optical cables, laid in the TMC, a method for monitoring the leakage of pipelines is proposed.
