Silica-silica low OH- PYROCOAT step-index fibers consist of a pure silica core with a silica cladding for high damage threshold and high performance optical properties. They have a low OH- concentration for efficient power transmission from visible through near-infrared wavelengths.

 Silica-silica low OH-fibers are coated with PYROCOAT polyimide for operation in extreme temperatures. In addition, hermetic coating under the PYROCOAT is also available for durability in the harshest environments.
