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.
