Abstract
An optical fiber resistant to hydrogen-induced attenuation losses at both relatively low and relatively high temperatures includes a substantially pure silica core and a hydrogen retarding layer. The hydrogen retarding coating may be made of carbon, metal, or silicon nitride. The fiber may also include a cladding layer, a second silica layer, and a protective outer sheath.
Claims15
An optical fiber comprising:
- a substantially pure silica core;
- and
- a hydrogen resistant layer at least partially surrounding the substantially pure silica core.
An optical fiber comprising means for reducing hydrogen-induced attenuation at both relatively low and relatively high temperatures.
