T175 Teflon High Strength FBG Temperature Cable



The T175 is a Single-Mode (SM) Fiber based Fiber Bragg Grating (FBG) High Strength Multipoint Temperature Sensing Array inside a loose, virtually frictionless, transparent Teflon tube. Written Through-the-Coating and featuring Bandwidths from 0.1nm to 50nm, Reflectivities from 1% to 90%, with ultralow Polarization Dependent Frequency Shift (PDFS) and Polarization Dependent Loss (PDL), and SLSR > 15dB.

Naturally packaged (written) directly in fiber, these high-strength sensing cables are further protected from strain by an outer Teflon tube. The T175 can be used on its own, or as a multi-point temperature compensation line running parallel with our T170 High Strength Sensing Cables, when the latter are used as multi-point strain sensors to 500kpsi, in temperature varying environments. Excellent wavelength to temperature linearity. Designed to make handling and installation fast, easy and intuitive. Delivers advantages inherent to all FBG sensors. Equally sensitive as traditional strain and temperature sensors but immune to EMI.

Key Features

Temperature Linearity. The precision made FBG structure written into the fibers’ core for producing the T175 yields a sensor configuration of high resolution, linearity, and measurement repeatability.

Daisy-chaining with no limits. Well suited for projects that include the need to monitor many points as the T175 is a ready to deploy Teflon FBG Array, available in customer defined distances between FBGs, and featuring a flexible and virtually limitless number of FBGs to match the requests of our customers. Standard connectors termination or spliced to specialty cables.

Low cost, easy installation, and long lifetime. The T175 was designed for projects that require both the availability of low-cost high-strength FBG arrays and stable operation for highly accurate measurements over the long-term. The original design makes handling and installation very easy. Fastening methods are by simple fiber bonding, laying, or embedding. Technica is happy to provide support and advice with regard to application specific installation and monitoring requirements.

Proven reliability and performance. The core technology used for reel-to-reel volume production of the T175 high strength sensing arrays has been developed over several years and received excellent customer feedback. The T175 is a product line enhancement that extends the range of addressable applications.


Applications include Security, Medical, Robotics, Structures, Energy, Industrial and R&D
