title = "Fault Warning and Analysis of Power OPGW Optical Cables Based on BOTDR/A",
abstract = "Aiming at the current demand for precise fault location and early warning of power OPGW optical cables, a method of OPGW optical cable fault location and early warning based on BOTDR/A technology is proposed. This paper proposes a method for locating the connection pole based on the DBSCAN algorithm. The connection point is located through the Brillouin frequency shift curve, and then the fault is accurately located. The Brillouin frequency shift is linearly affected by temperature and strain, which are linear relationships and cross-sensitive. The isolation of the OPGW cable strain and temperature is achieved by the identification result of the fiber optic splicing point. The abnormal region is positioned and warned by strain measurement. Field picture collections are performed for typical abnormal strain areas, and the positioning and cause of fault warning is confirmed. The OPGW fault positioning and early warning method proposed herein, significantly improves the efficiency of fault processing and improves the operational reliability of OPGW optical cables.",
