Product Description

Verrillon® VHS500 is a pure silica core single-mode design available with all Verrillon harsh environment coating combinations, including Polyimide, Silicone-PFA, Silicone-MTA, MTDA and Carbon, which can be applied in conjunction with any of these polymeric coatings. Typically, these fibers are used in downhole distributed sensing techniques for temperature, pressure, acoustics and seismic, as well as in data logging and imaging applications.
Our carbon-coated optical fibers provide exceptionally high levels of hermeticity compared to commercial fibers. We provide extensive data that demonstrates the performance of our fiber in simulated well conditions.
Consistent with our founding principles, we specialize in application-optimized fibers, providing our customers unmatched flexibility in their system design and performance.
