Fiber Optics Sensors are devices that use optical fiber technology to detect and measure physical parameters in their surroundings. These sensors leverage the principles of light propagation through optical fibers to monitor various environmental factors. Fiber optics sensors offer advantages such as high sensitivity, immunity to electromagnetic interference, and the ability to cover long distances without signal degradation. Different types of fiber optics sensors exist, each tailored to measure specific physical quantities.
We demonstrate fiber optic sensing systems in a distributed fiber sensor network built on existing telecom infrastructure to detect temperature, acoustic effects, vehicle traffic, etc. Measurements are also demonstrated with different network topologies and simultaneously sensing four fiber routes with one system.
We demonstrated for the first time that geographic locations on deployed fiber cables can be determined accurately by using OTDR distances. The method involves vibration stimulation near deployed cables and distributed fiber optical sensing technology.
