FBG Interrogation Units
The key to a successful optical fiber sensor installation is the interrogation unit which is used to illuminate the sensor network and interrogate the optical reflection from each sensor. Smart Fibres recognizes the diversity of optical fiber sensing applications, and the differing requirements of each for speed, accuracy, sensor count, size, weight and cost.

Because of this, we offer a wide range of tried and tested interrogator solutions to suit existing applications and are continually developing this range with our technology partners in response to new market demands. For our more unique or demanding customer requirements, we offer custom interrogation unit developments.
