论文摘要
光纤网络已成为全球基础架构。除了电信的基本功能外，其感应能力还引起了越来越多的关注。在本文中，我们讨论了用来窃听家用纤维的风险，并在实验室中展示了其性能。在家用光学调制解调器前面使用3米尾纤维，可以通过激光干涉仪窃听正常的人言语声音，并恢复1.1公里。定量分析检测距离极限和系统噪声。我们还提供了一些实用方法来防止窃听家用纤维。
The optical fiber network has become a worldwide infrastructure. In addition to the basic functions in telecommunication, its sensing ability has attracted more and more attention. In this paper, we discuss the risk of household fiber being used for eavesdropping and demonstrate its performance in the lab. Using a 3-meter tail fiber in front of the household optical modem, voices of normal human speech can be eavesdropped by a laser interferometer and recovered 1.1 km away. The detection distance limit and system noise are analyzed quantitatively. We also give some practical ways to prevent eavesdropping through household fiber.
