In this paper, the practical WDM multi-granularity traffic switching testing network is constructed and a novel method using eye diagram to monitor optical performance in the network is proposed. The method is demonstrated in the reconfigurable WDM multi-granularity traffic switching all-optical network and it results that it can realize supervision of optical signal to noise ratio, time jittering, channel power, extinction ratio and bit error rate of optical data stream of any wavelength channel in the network. The method is transparent to signal protocol and bit rates and is able to distinguish between different optical impairments.

摘要波分复用多粒度交换可重构全光网是当前光通信网发展的方向，该文构造了一种实际试验网，提出了一种&眼图法&对网中数字光信号进行全面监控的方法，并在自建WDM多粒度交换可重构全光网试验床上进行了演示，结果显示在网络重构等各种条件下均可对网中各波长通道数字信号的信噪比、定时抖动、功率、误码率等进行实时监测控制，该方法对光信号的协议和速率透明且能对各种光性能劣化进行鉴别。
