The grating acts as a mirror reflecting only a very precise wavelength (colour)

When the optical fiber is stressed or when its temperature is modified, the wavelength varies proportionally.


Different sensors made of gratings having specific reflecting wavelengths can be implemented in series on a single optical line (typically up to 16)

Overcome the sensing frontiers with optical measurement

  • Easy and reliable handling of the optical fiber cable
  • High resistance to cyclic fatigue
  • Intrinsically non explosive
  • Perfect strain transfert
  • No EMI sensitivity
  • No corrosion, no drift
  • Sensors can be added and combined on a single line
