摘　　要：光层监测是下一代光网络自动控制的关键方法,除实时反应和对邻近信道的保护外,在维持有效的高服务质量(QoS)时,光性能监测也确保了构建和控制复杂拓扑网络的能力。文章分析了在光层里光参数变化对光信号性能的影响以及光信号性能监测选项的评估,并对光信道性能监测设备(OCPM)进行了简要描述。It is pointed out that optical layer monitoring is a key enabler for self-control of next generation optical networks. Aside from its real-time feedback and the safeguarding of neighbouring channels, optical performance monitoring ensures the ability to build and control complex network topologies while maintaining an efficiently high QoS. In this paper, it is analyzed that Parameter variations and their effect on signal performance in optical layer as well as evaluation of performance monitoring options, and describe optical channel performance monitor simply.
