光纤传输网具有独特的优势,但也有特殊的脆弱性。随着光纤通信技术的快速发展和广泛应用, 光纤传输网的安全性显得越来越重要。文章按照分层的观点, 介绍了光纤传输网的安全分层结构, 分析了光纤传输网不同层面的脆弱性和所受攻击的类型及方法, 并针对各层可能受到的安全威胁, 研究了相关的安全对策。

Fiber-optic transmission networks have unique advantages and special vulnerabilities. Their safety has becomes more and more important with the rapid development and extensive applications of the fiber-optic communication technologies. In line with the hierarchical point of view, this paper introduces their safety hierarchical structure, analyses the vulnerabilities of their different layers, types and methods of attack and investigates the relevant safety strategies against the possible safety threat to each layer.
