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.
