Technical Basics

The use of Optical Fibres has drastically increased the last 2 decades, especially in the fields of data transmission, optical sensors, analog and digital data connections, laser power guiding and special effects lighting applications.
Most important reasons for using fibre optics are            

There are several types of fibres we use

Typical coating materials are acrylate  (one or two layers) and polyimide .

As optical connectors mostly FC/APC connectorization is used in our systems.

The Fibre Bragg Grating (FBG) reflects light with a certain frequency (Color) which is determined by by the physical structure of the grating.  This frequency shifts by strain or heat which is locally induced in the active sensor region.  

FBG - Sensors for Material Strain Monitoring show following advantages:

Most important technical features of the FBG for strain sensors are:
