Abstract
The fatigue resistant optical fiber is fabricated by producing an optical fiber having an electrically conducting surface, heating the produced optical fiber, and coating the heated optical fiber with a material impervious to water and water vapor.
Claims30
A method of fabricating a fatigue resistant optical fiber, comprising the steps of:
- producing a completely formed, unsupported optical fiber having an electrically conducting surface;
- heating said produced optical fiber;
- and
- coating said heated optical fiber with a material impervious to water and water vapor;
- said step of producing including the steps of
- preparing an optical preform by a chemical vapor deposition technique,
- preparing an electrically conducting silica substrate tube containing carbon,
- placing said preform inside said tube, and
- collapsing said tube onto said preform to provide said produced optical fiber.
