AFLglobal.com | 800.235.3423 Features • Highly compatible with standard single-mode fibers for ease of spliceability • Combined with carbon coating, VHS100 exhibits very high resistance to hydrogen and moisture in the mid-range of temperatures • Available with all Verrillon ® Harsh Environments coatings • VHS100 is designed to operate at both 1310 and 1550 nm wavelengths • Typically used with single-mode DTS and DAS sensing interrogators VHS100 Series Harsh Environment Fibers Verrillon VHS100 Series of single-mode fibers are suitable for low to mid-temperature harsh environment applications. VHS100 has the best performance in hydrogen when coated with our hermetic coating. Depending on the specific application, VHS100 is available with a diverse range of coatings including Carbon Mid-temp Dual Acrylates (CMTDA), Carbon Silicone Mid-temp Acrylates (CSMTA), Carbon Silicone-PFA and Carbon Polyimide.
