摘要
对现有光传输链路性能监控技术进行了比较,提出了一种基于带内光信噪比、快速灵活的光性能在线监测方法,并进行了建模分析,搭建了色散在线监测系统。对系统性能的主要技术指标进行测试分析的结果表明,该方法进行超高速光传输链路色散在线监测时,与链路数据速率及调制格式均无关,有效实现了传输链路色散在线监测功能。
The paper compares the existing optical transmission link performance monitoring techniques, and proposes an approach based on in-band optical signal to noise ratio, fast and flexible optical performance on-line monitoring method, then conducts a modeling analysis and build a dispersive line monitoring system. The results of the system performance test analyzes the main technical indicators show that the method of ul- tra-high-speed optical transmission links when dispersion on-line monitoring, which are independent of the link data rate and modulation format, the system can achieve a transmission link dispersion online monitoring.
