One Fiber — Optical Fiber Sensors

HBM’s recently developed optical sensor series called newLight allows large strain measurement ranges at better long-term stability. It is a suitable choice for structural health monitoring because of its quick and easy installation as well as its resistance to environmental circumstances, for example, humidity, salt, and rust even over very long distances.

The sensor series newLight’s compatibility with regular telecom cables makes it very cost effective — particularly for medium-to-high channel applications. This series is based on the Fiber Bragg Grating technology and provides optical sensors for measurements of temperature, accelerometer, strain, and tilt.

Easy to Handle

  • Sturdy designs
  • Adaptable with telecom fiber for long-distance measurements
  • Easy installation resulting in lower setup costs


  • Choice of wavelengths, connectors, and cable types available
  • Bare fiber with many FBGs
  • Numerous sensors assembled in arrays with spliced connectors for speedy installation


  • High fatigue and high strain resistance
  • Varied sensor formats
  • Reinforced or dielectric for applications in various risky zones
  • From basic FBG to complicated sensor designs

Select the Right Optical Sensor

Individual sensors with or without plugs can be selected. Alternately, you can choose a group of sensors connected on the same line for easy installation.
