VHM3000 Series Harsh Environment Fibers

Verrillon® VHM3000 Series of Graded-Index (GI) multimode optical fibers are suitable for high temperature applications up to 300°C in hydrogen containing environments. The high bandwidth of these fibers allows Distributed Temperature Sensing (DTS) systems to achieve extremely short spatial resolution in multi-kilometer deep/long deployments.

PRODUCT DESCRIPTION

Verrillon® VHM3000 Series is a family of graded-index multimode fibers exhibiting exceptional resistance to hydrogen at high temperatures in hydrogen-rich applications. The true hydrogen resistance is a result of modified glass chemistry. Additionally, the graded-index design provides very high bandwidth for optimum DTS measurement in downhole applications. The VHM3000 Series is available with a variety of Verrillon coatings including Polyimide, Silicone/PFA and Mid-Temp acrylates. Typically, these fibers are used in down-hole data logging, distributed sensing and imaging applications.
