We introduce a novel multiplexing technique applied to optical fiber distributed sensors, based on optical backscatter re-flectometry (OBR) and high-scattering MgO-doped fibers. In this paper, we demonstrate the possibility of simultaneously detecting multiple fiber with a single scan using an OBR distributed sensor, and successfully...

Optical Backscatter Reflectometer (Luna OBR 4600 ) can transform a single mode fiber SMF in an efficient spatially distributed sensor of temperature and strain Unfortunately, t he operation field of OBR is limited to a single sensing fiber element . A parallel of multiple fibers is problematic as t he back scatter ed power to disc rimi nate is...
