Product Description

AFL's Verrillon VHM7000 Series graded-index, bend-insensitive multimode fiber is suitable for mid-range temperatures where the carbon coating is a true barrier against hydrogen diffusion that causes undesirable optical absorption in the operating spectral region of most optical sensors. It has the added benefit of low bend loss for use in tight bend applications.

With their optimized optical design, VHM7000 fibers are engineered to operate under extremely small bend radii down to 7.5 mm. The low bend loss provided by VHM7000 Series fiber makes it the fiber to use in tight bend applications.

VHM7000 is available with polyimide, silicone-PFA, silicone-MTA, MTDA and carbon coatings which allow it to withstand high temperatures and hydrogen-containing atmospheres. Carbon coating can be applied to provide hermeticity against water and hydrogen in downhole applications and for fatigue resistance in long-term deployments.

VHM7000 is available at prooftest levels of 100 kpsi and 200 kpsi.
