Distributed Fiber Optic Sensing (DFOS)

Distributed Fiber Optic Sensing (DFOS) is a technology that uses fiber optic cables to continuously monitor physical conditions like temperature, strain, or vibrations along their entire length. By sending light through the fiber and analyzing changes in the reflected signals, DFOS provides real-time data over long distances—often kilometers—without the need for multiple sensors. This capability makes it ideal for applications such as infrastructure health monitoring, security, and energy systems, offering precise, non-intrusive, and remote sensing over extended areas.
