摘　　要：Optical performance monitoring using asynchronous optical or electrical sampling has gained considerable attention. Relative clock wander between data signM and sampling source is a typical occurrence in such systems. A method for the quantitative monitoring of the relative clock wander in asynchronous optical under-sampling system is presented. With a series of simulations, the clock wanders recovered using this method are in good agreement with the preset clock wanders of different amounts and frequencies for both RZ and NRZ signals. Hence, the reliability and robustness of the method are proven.Optical performance monitoring using asynchronous optical or electrical sampling has gained considerable attention.
