Optical Labels Enabled Optical Network Performance Monitoring

Optical performance monitoring (OPM) technology, especially the optical power and OSNR of each WDM channel, are of great importance and significance that need to be performed to ensure stable and efficient operation and maintenance of network itself. In this paper, we present our recent research activities and progresses on optical-label enabled OPM. Simulation results of WDM system show that the maximum error of channel power monitoring and OSNR estimation are less than 1dB after 20-span transmission. It confirms that the optical-label enabled OPM has lower cost and higher efficiency for mass deployment in practical WDM networks.
