| 摘 要： | 随着光纤技术的飞速发展，光纤链路的安全性受到了极大的挑战。为了对光纤链路的安全状况作一定性分析，根据一种天线模型对单模光纤的弯曲辐射功率进行了理论推导，并对单模光纤的弯曲辐射功率随弯曲半径和探测器面积的变化情况做了仿真模拟，给出了分析结果。结果表明，对弯曲光纤实施窃听是完全有可能的。

| Abstract: | With the rapid development of optical fiber technology, the security of optical fiber link faces utmost challenge. In this paper, in order to make a qualitative analysis of the secure situation of the optical fiber link, the radiant power of curving optical fiber is derived theoretically based on an antenna model, a simulation analysis for the relationship between curvature radii and area of detector changing with the power of the curvature radiation is also made, and finally the analytical result is given. The result shows that it is possible to wiretap the curving fiber. |
