Fiber Optic Distributed Sensing

Fiber optic distributed sensing overcomes the inherent limitations of traditional technologies (thermocouples, strain gauges) and enables monitoring solutions with unrivalled advantages for the protection of people and critical assets, especially when monitoring in inaccessible or inhospitable environments.

In a distributed sensor, the whole optical fiber is the sensor itself.

Optical fiber is light, pliable, and immune to electromagnetic interference (EMI), which makes it a cost-effective, flexible and an inert sensor medium. The fiber is integrated in a valuable asset (structure, pipeline, cables, etc.) in a dedicated cable. A single optical fiber can replace thousands of traditional single-point sensors, providing a significant reduction in installation, calibration, and maintenance costs. In addition, assets can now be monitored where previously this was impractical due to their size, complexity, location or environment.

Why choose distributed sensing?

  • Distributed sensing replaces complex integration of thousands of sensor with one optical fiber system
  • The inherent distributed sensing nature of fiber optic sensors can be used to create unique forms of sensors for which, in general, there may be no counterpart based on conventional sensor technologies.
  • Optical fiber is cheap, light, pliable, and immune to electromagnetic interference (EMI), which makes it a cost-effective, flexible and an inert sensor medium.
