Corning’s High Temperature and Harsh EnvironmentFiber is designed for applications requiring improved fatigue resistance, high usable strength, and excellent resistance to high temperature and hydrogen permeation. The fiber consists of Single Mode or Multimode core and dual coating system, including hermetic carbon layer and followed by high temperature polyimide layer.

Corning’s specially designed hermetic layer provides a protective barrier to help shield the glass from exposure to hydrogen, water, and corrosive chemicals. It extends the lifetime of fiber by stopping fiber fatigue. Corning’s hermetic layer is a thin layer of amorphous carbon that is bonded directly to the glass surface of an optical fiber. Second coating, high temperature polyimide material allows fiber to operate in environment up to 300oC. The fiber is manufactured with Corning’s patented OVD (outside vapor deposition) process.
