It is used around the world to monitor power stations, telecom networks, railways, roads, bridges, international borders, critical infrastructure, terrestrial or subsea power cables or pipelines, and downhole applications in oil, gas and enhanced geothermal electricity.

Distributed and quasi-distributed fiber optic sensors are systems that connect opto-electronic interrogators to an optical fiber (or cable), converting the fiber to an array of distributed sensors. The fiber becomes the sensor while the interrogator injects laser energy into the fiber and detects. Fiber optic current sensors are revolutionizing the way electrical currents are measured, providing high sensitivity, immunity to electromagnetic interference (EMI), and the ability to function in harsh environments. However, the current literature contains. Generally used for plastic fibers. High-precision type, consisting of a core (transmitter) and surrounding area (receiver). The operating position can remain the same regardless of the direction from which the target enters the detecting area. This is possible because when a fiber undergoes a physical change, such as bending, the light passing through it.
