Fiber sensing uses the physical properties of light as it travels along a fiber to detect changes in temperature, strain and other parameters. Fiber Sensing can be measured using discrete sensors or by using the fiber itself – this is called Distributed Fiber Sensing. The device measuring the fiber itself are generally called interrogators. The purpose is to use a standard or specific fiber for measuring the temperature and strain along it using Raman and Brillouin Distributed Fiber Sensor techniques.
For instance, using fiber sensing interrogator, one can:
- Detect and locate any hot spot along your power cable.
- Detect and locate any excessive strain on your optical cable and react before the break.
