• VHM2000 Series Harsh Environment Fibers


    • 50/125 graded-index multimode fiber for use in harsh environments
    • Available with a wide range of protective coatings, depending on application requirements
    • Suitable for use in mid temperature range applications VHM2000 with carbon coating provides exceptional resistance to H2 and moisture ingression
    • High bandwidth (>300 MHz*km) allow DTS measurements with extremely short spatial resolution


Verrillon® VHM2000 Series fibers are designed for mid-temperature range applications. In addition to the glass performance, VHM2000 coated with our hermetic carbon show an exceptional performance in hydrogen-containing applications. . VHM2000 is available with a variety of coatings and coating combinations, including Polyimide, Silicone-PFA and Carbon. Typically, these fibers are used in down-hole temperature and acoustic monitoring, data logging, distributed sensing and imaging applications.
