Home / Fiber Optic Cable Induction Detection Method
The system and method provides means for detecting fiber optic cable embedded within a structure such as a wall of a building. What can be detected is the cable strengthening, the jacket, the trenching, the ducts they are in and if included. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Fiber optic cable intrusion detection sensors work by utilizing changes in light transmission through optical fibers to detect unauthorized entries or breaches.
