Advantages of fiber optic sensors

Optical fibers can be compared to the nervous system in a human body. The nerves give us accurate and real-time feedback about the health condition of our bodies. In a similar way, optical fibers can be applied in and on a variety of physical structures and give this structure a “feeling”. Any change and degradation are sensed in real-time by these optical fibers. 

Why Fiber Optics


Sensor / cable lifetime >20 years

Passive Sensor

No electrical power at the measurement point

Long distance

Remote monitoring (50 km and more)

High sensitivity and accuracy

At sensing point Insensitive lead in to reduce disturbances

Harsh and explosive environments

Resistant to corrosion, lightning, etc.

Immune to EMI

Electromagnetic interference


Zone based

  • Zone-based (up to 500m perimeter length/zone) and 16 zones/unit
  • Total perimeter length up to 8 km/unit (depending on fence type)
  • Cost-effective zone-based solution
  • Fence mounted and buried sensors (carpet)
  • Ground: sensitive only directly on top of the carpet


  • Pin point – Quasi-distributed monitoring (+- 5m local resolution)
  • Perimeter length max. 1,6km / unit Cost-effective up to 7 km trip. (depending on fence type)
  • Well established platform used for 100+ Fiber optic sensing projects since 2010
  • Fence mounted sensor system
  • Additional monitoring of manholes/gates with the same system
  • Different sensitivity and data analysis for each section


  • Pin point – Distributed monitoring (+- 5m local resolution)
  • Two versions up to 20km or 50 km length, therefore, cost-effective solution compared to DAS systems
  • Fence / wall mounted preferred
  • Different sensitivity levels adjusting to environmental conditions of each section (HW & SW)
  • Full sensitivity and bandwidth throughout the whole fiber length
  • Globally well established and accepted solution since 2011

End-to-End Solutions

We provide all necessary parts for a complete installation. This covers the interrogation unit, the sensing cable and all required accesories.
Our solutions can either be used in a standardized out of the shelf way, or they can be fully tailor made exactly to the challenges of your perimeter.
NBG has developed one common software platform for all its systems. This gives you access to all the powerful algorithms and interface possibilities.
