FBG Principle

Fiber Bragg Gratings are made by laterally exposing the core of a single-mode fiber to a periodic pattern of intense laser light. The exposure produces a permanent increase in the refractive index of the fiber‘s core, creating a fixed index modulation according to the exposure pattern. This fixed index modulation is called a grating.

DTG® & FSG® Technology

DTG®s and FSG®s offer unique characteristics compared to classically produced FBGs, such as extremely high breaking-strength, spliceless array configuration and uniform coating coverage. FBG parameters and coating material can be selected based on customer needs.

ORMOCER® Coating

ORMOCER® short for Organic Modified Ceramics describes a group of hybrid polymer materials which offer some unique properties applicable to different applications. They are composed of inorganic oxidic structures, that are cross-linked or substituted by organic groups.

Wavelength Division Multiplexing

Wavelength-division multiplexing (WDM) is a technology which originates from the telecommunication industry and defines the use of multiple optical signals onto a single optical fiber by combining different wavelengths (i.e., colors) of light.

Optical Frequency Domain Reflectometry

Optical Frequency Domain Reflectometry (OFDR) is a special technology which is used for the analysis of optical light paths and reflection characteristics in optical fibers and components.

Time Division Multiplexing

A third measurement technique for FBG interrogation is based on the optical path length difference and hence the travel time of the light („Time of Flight “) between different fiber Bragg gratings along one optical fiber.

Fiber Tagging

When servicing data transmission cables, one is often required to be able to distinguish data conduits from each other. For electrical data transmission lines, it is known to utilize unique resistors attached along such conduits to serve as identification markers or labels.
