OFS Introduces New, Thermally Stable PYROCOAT® K Optical Fiber

OFS, a leading designer, manufacturer, and supplier of innovative fiber optic products will highlight its new PYROCOAT K Optical Fiber at the Photonics West Exposition being held at the Moscone Center in San Francisco, California from 27 January through 1 February 2018, booth #1430

PYROCOAT K Optical Fibers offer an improved coating that enables wider operating temperatures than any commercially available polymer-coated fibers. With its reliable performance for fiber optics in extreme conditions, PYROCOAT K Optical Fiber provides thermal stability over various continuous temperatures/lifetimes: 275°C for 80 years, 300°C for 13 years, 325°C for 2.2 years, and 350°C for 18 days. These new optical fibers can also withstand short excursions at even higher temperatures, and long-duration stability at low temperature extremes, at and below -65°C.

Mr. Michael Hines, OFS Market Manager for Industrial Sensing states “We’re excited to add PYROCOAT K Optical Fiber as a problem-solving technology to the growing family of LineaSens® distributed sensing products. OFS has quantified the reliability of optical fibers over a broad range of high operating temperatures, closing significant, industry-wide performance gaps and opening new opportunities for optical fiber use in harsh environments.”

“The PYROCOAT K Optical Fiber development illustrates the OFS long-term commitment to the fundamental sciences that enable fiber optics to extend into new and exciting market areas.” Added Dr. Jane Cercena, Senior Vice President, OFS - Specialty Optical Fiber.
