Abstract

We demonstrate multi-detection and recognition of mechanical events over 50km of SSMF with coherent homodyne phase-OTDR using novel Pol-Mux orthogonal interrogation codes. Pattern identification of an engine noise is highlighted, paving the way for numerous smart-city/industrial monitoring applications over already deployed telecom fibers.
