T15 Steel Anchored FBG



The T15 is a Polyimide or Gold Coated Single-Mode (SM) Fiber based Fiber Bragg Grating (FBG) factory-bonded to a stainless steel pad or “anchor”. The proprietary non-slip mass-manufacturing process used for producing the T15 yields ultra-high consistency and enables direct and immediate field installation of the FBG to many types of surfaces by spot-welding, screwing-in, or chemically bonding the FBG’s steel pads to the respective surfaces.

Available in a wide range of optical and mechanical specifications.
Naturally packaged (written) directly in fiber, these FBGs can be
used as they are or they can be packaged into a variety of higher
level components and devices for use in optical systems. Smallsize
and fast response time. Excellent wavelength to temperature
and wavelength to strain linearity. The T15 FBG is designed to
make handling and installation fast, easy and intuitive. Delivers the
many advantages inherent to all FBGs.

Key Features:

Temperature and Strain Linearity. The precision made FBG structure written into the fibers’ core for producing the T15 yields a simple transducer configuration of high resolution, linearity, and measurement repeatability. High SLSR for clear signal processing.

Easy installation. The T15 aims to eliminate the need for civil, industrial, medical, security, rail, marine, aerospace, energy and other engineers and researchers to all become materials experts for bonding polyimide and gold coated fibers onto various surfaces or into various higher level sensor designs that are needed for their various applications. Ideally balancing cost, performance and reliability the T15 is here to simplify the process of using Fiber Bragg Gratings, and to accelerate the creation of new and attractive fiberoptic based commercial solutions. Available for fibers with diameters from 70µm to 155µm and with standardized and custom size stainless steel pads “anchors”.

Easy to daisy-chain. Well suited for projects that include the need to provide optical filtering, to monitor strain, temperature and other engineering parameters at many points. The T15 can be provided as a single FBG optical component or in FBG Arrays of various lengths, with a flexible number of FBGs and steel anchors located at customer specified distances along the fiber.

Proven performance and reliability. The T15 Stainless Steel Anchored FBG is a rugged low-cost optical component assembly with stable operation for highly accurate and reliable long-term use. The T15 is a core element for an expanding range of optical devices and applications.
