With the rapid development of communication networks, the optical phase conductor (OPPC) is now widely used in power communication systems. However, their complex operating conditions make existing monitoring methods less effective for fault and leakage detection. This paper proposes an online monitoring method using Brillouin optical time domain analysis (BOTDA) and geographic information system (GIS) technology. A mathematical model of cable temperature changes is built, and BOTDA captures distributed temperature data. GIS helps locate faults, while the random forest algorithm classifies fault types. Simulation results show that under a 4∘C/h temperature change and wind speed up to 9.32 m/s, the method performs well. Prediction errors for ice thickness stabilize as ice accumulates. The random forest algorithm achieves 95.56% average accuracy within 9.65 seconds. This approach enables real-time, accurate monitoring, supporting efficient maintenance of power communication networks.
