[0002] In power transmission lines, OPGW optical cables, as components with both communication and ground wire functions, are widely used in high-voltage transmission lines. Traditional OPGW optical cables mainly bear the functions of communication and lightning protection. However, with the development of smart grids, higher requirements are put forward for the performance of optical cables.

[0003] Existing optical cables cannot judge the working state and environmental changes of the optical cables. When abnormal conditions occur in the optical cables, they cannot timely discover and take corresponding processing measures, and cannot guarantee the stable and safe operation of the optical cables.
