One essential requirement for guaranteeing the secure and reliable functioning of the electricity system is the regular functioning of fiber optic cable connections. To timely grasp the real-time operation status of the fiber optic lines, the study proposes a fiber optic cable performance monitoring method based on a variety of environmental parameters. This method involves the measurement of optical fiber-type light intensity of the fiber optic cable line, which is used for safety monitoring, monitoring and analysis of fiber optic cable lines, and the design of a fiber optic cable outer layer broken strands of high precision monitoring method, which combines fiber grating sensing. To optimize the monitoring method of fiber optic cable performance, the study was based on fiber optic coupling efficiency and numerical aperture for parametric measurement loss analysis. The results indicated that the signal-to-noise ratio of the fiber optic sensor can be up to 152 and 157 dB, and the response frequency can be up to 6233 and 6315 times/s. Adjusting the bending radius can effectively control the degree of loss of the optical fiber. Compared with 1550 nm, the loss of single-mode fiber G.6521 at 1310 nm wavelength was much lower than that of multi-mode fiber. It can be observed that the monitoring method proposed by the study is an effective means of monitoring the defects of optical cable operation, providing reliable protection for the fault monitoring of the outer layer of the cable in remote areas, improving the operational efficiency of the power system, and effectively monitoring the performance of the cable. This is crucial to implementing the management of the optical cable's safety performance assessment since it establishes the framework for it.
