  • High Temperature Acrylate Coated Single Mode Fiber

    TFO’s high temperature acrylate coated single-mode fibers are designed for continuous use at +150℃. The fibers are available with different Numerical Aperture (NA) ranges to give various levels of macro and bend losses and Mode Field Diameters(MFDs) to give optimum choice depending on the application.
    High temperature acrylate coated fiber is primarily designed as a low attenuation fiber for use as a distributed sensor for Distributed Temperature Sensing (DTS), Distributed Pressure Sensing (DPS), Distibuted Strain Sensing (DSS) and Distributed Acoustic Sensing (DAS) applications. The higher cut-off wavelength than standard telecoms fibers allows this fiber to offer improved bend losses over standard single-mode fibers.
