A Novel WDM Monitoring Method

A Novel WDM Monitoring Method A novel method to monitor the performance of WDM channels in an optical network is presented by analyzing the photo-diode current of a detected optical signal. From the photo-diode current, an amplitude histogram is generated, hereafter to be called the probability density function (PDF). By analyzing the PDF information is obtained about several monitor parameters including the optical power as well as the noise-levels of the channels. A wavelength dependent attenuator has to be used to extract the monitor parameters uniquely. Experimental evidence is given to demonstrate that the method can be used to analyze at least three WDM channels simultaneously. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals

Abstract

A novel method to monitor the performance of WDM channels in an optical network is presented by analyzing the photo-diode current of a detected optical signal. From the photo-diode current, an amplitude histogram is generated, hereafter to be called the probability density function (PDF). By analyzing the PDF information is obtained about several monitor parameters including the optical power as well as the noise-levels of the channels. A wavelength dependent attenuator has to be used to extract the monitor parameters uniquely. Experimental evidence is given to demonstrate that the method can be used to analyze at least three WDM channels simultaneously.
