It is shown that noise level can be monitored by direct optical spectrum analysis using no polarization analysis or coherence properties and avoiding the need for data demodulation.2013http://zaguan.unizar.es/record/14983110.1109/ICTON.2013.6602731http://zaguan.unizar.es/record/149831oai:zaguan.unizar.es:149831info:eu-repo/grantAgreement/ES/MICINN/PTQ-11-04805info:eu-repo/grantAgreement/ES/MICINN/TEC2010-17869info:eu-repo/grantAgreement/ES/MICYT/TSI-020100-2011-423info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2012-38119International Conference on Transparent Optical Networks 1, 5 (2013), [4 pp.]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
