Verrillon® VHS100-HiNA Series is a family of small form factor (SFF), bend-insensitive, reduced cladding single-mode fibers designed for harsh environment small packaging applications where tight bend and hydrogen resistance are key requirements. These fibers have an 80 μm cladding diameter suitable for extremely small fiber coils used in interferometric sensing applications. In addition to the small size, this fiber is coated with Verrillon’s renowned hermetic carbon coating, which makes it extremely resistant to static fatigue for longer lifetimes. The VHS100-HiNA fiber family is available in high proof-test levels ranging from 100 to 300 kpsi.
