摘要
光传输网络安全问题日渐突出,迫切需要一种能有效解决信息传输安全问题的加密设备。分析了同步数字体系(SDH)的帧结构特点,结合SDH设备的组网方式,设计了一种基于SDH的155Mb/s光传输加密设备,并详细阐述了该设备各组成模块及其具体实现方法。实验证明,该设备与SDH光传输设备组网使用,引入传输延时低,传输可靠性高,有效提高了SDH光网络信息传输的安全性。
Optical transmission network security issues have become increasingly prominent, the urgent need for a encryption device which can effectively solve the problem of information transmission security. This pa- per analyzes the characteristics of the frame structure of SDH, combined with SDH networking equipment, designs a 155Mb/s optical transmission encryption device based on SDH, and introduces the components and the specific implementation method of device. The experiment proves that the combination of the device and SDH optical transmission equipment used in network, the introduction of low transmission delay and high transmission reliability can effectively improve the security of SDH optical network information transmission.
