Experimental verification of an eye diagram reconstruction technique based on asynchronous undersampling

In this paper we experimentally demonstrate an eye diagram recovery technique, applied after asynchronous undersampling of a high speed optical communication signal. The resulting (reconstructed) eye diagrams are compared with the ones obtained by traditional (synchronous) techniques for different optical signal to noise ratios. This technique is being applied in the development of complete eye diagram analyzer equipment for BER estimation and network performance monitoring.
