VHM4000 Series Harsh Environment Fibers

Verrillon® Harsh Environment VHM4000 Series is a family of Step-Index (SI) multimode fibers with excellent resistance to hydrogen darkening at high temperatures and pressures. These SI fibers are suitable for applications where moderate lengths of fiber are required and where hydrogen is present in high concentrations. VHM4000 fibers are available in 50/125 and 62.5/125 micron designs.

PRODUCT DESCRIPTION

Verrillon® VHM4000 product is a multimode step-index with a pure silica core for high resistance to hydrogen darkening. This product is available in both 50/125 and 62.5/125 versions. This design is available in a variety of coatings including Polyimide, high temperature acrylates, Silicone-PFA and hermetic Carbon. Typically, these fibers are used in down-hole distributed sensing and imaging applications where the temperature and hydrogen partial pressures are extreme. Due to its step index design, the VHM4000 product is suitable for short distance applications where the spatial resolution requirements are not extreme.
