Abstract:Currently, 5G network construction continues to accelerate, with mobile communication networks expanding at an exponential rate. As a core infrastructure component of communication base station power supply systems, the operational stability and reliability of power cables directly impact the service quality and user experience of the entire mobile communication network. This paper systematically analyzes the physical principles, implementation mechanisms, and applicable scenarios of three mainstream fault location technologies: time-domain reflectometry, frequency-domain reflectometry, and traveling wave method. It innovatively proposes an intelligent fault location strategy based on multi-parameter data fusion, providing mobile communication operators with an economical, efficient, precise, and reliable cable operation and maintenance solution. This approach significantly enhances the availability and maintenance efficiency of network infrastructure.
