Abstract: The terrain and climate in Yunnan are complex, and cable lines often exist security risks. The normal operation of optical fiber cable is an important condition for guaranteeing the safe and stable operation of the power system. To grasp the real-time operating status of the optical fiber line in time is the basic premise to ensure the smooth flow of information in the power system. Firstly, this paper constructs an optical fiber cable temperature monitoring system based on optical fiber sensor network. It consists of application layer, transmission layer, and detection layer. Then it studies the optical fiber sensing temperature detection technology and establishes the sensor subsystem and data acquisition processing. The optical fiber cable temperature monitoring system of the sub-system was finally subjected to a simulation experiment to monitor and analyze the temperature or abnormal information of the optical cable, which lays the foundation for the realization of the optical cable safety assessment management, and improves operational efficiency and makes a contribution for building a modern, informative and intelligent power grid.
