Application of Optical Fiber Sensor in All-Optical Network Security and Prevention

全光网络是使用光波技术完成数据传输、信号交换的一种网络模式,其核心组成是光传输系统及光节点。本文首先介绍了全光网络在运行过程中遭受的几种常见攻击方式,包括带内、带外干扰攻击、非法探测等;其次,重点分析了光纤传感器的传感原理以及在全光网络安全及防范中的实践应用;最后,从各种光纤传感技术的应用效果来看,传统的基于瑞利背向散射的传感技术、基于拉曼背向散射的传感技术等均存在局限性。本文提出了一种全分布式光纤传感系统,进一步提高了测量精度,在保障全光网络安全方面应用效果更好。

All-optical network is a network mode that uses light wave technology to complete data transmission and signal exchange.Its core components are optical transmission system and optical nodes.In this paper,several common attack modes are introduced in the operation of all-optical networks,including in-band and out-band interference attacks,illegal detection,etc.Then the sensing principle of optical fiber sensor and its practical application in all-optical network security and defense are analyzed.From the perspective of the application effect of all kinds of optical fiber sensing technology,the traditional sensing technology based on Rayleigh backscattering,sensing technology based on Raman backscattering,etc all have limitations,this paper based on this,advances a kind of distributed optical fiber sensing system,further improve the accuracy of measurement,the application effect is better in terms of all-optical network security.
