Receiver-Based Experimental Estimation of Power Losses in Optical Networks

We propose a method to estimate the amplitude of an unexpected power loss which, leveraging on calibration, enables real-time monitoring network link. It is based existing fiber-longitudinal profile evaluation technique. The reliability assessed experimentally. When anomaly located at 0 km from beginning span, estimation bias smaller than 0.2 dB for losses up 10 dB. 25 same observed but 5 In both cases, standard deviation
