Abstract: Distributed Fiber Optic Sensing (DFOS) systems rely on measuring and analyzing different properties of the backscattered light of an optical pulse propagating along a fiber cable. DFOS systems can measure temperature, strain, vibrations, or acoustic excitations on the fiber cable, and to their unique specifications, they have many applications and advantages over competing technologies. In this talk, we will focus on the challenges and applications of DFOS systems using outdoor-grade telecom fiber networks instead of standard indoor or some specialty fiber cables.
