| 摘要 |
An optical fiber (10) resistant to hydrogen-induced attenuation losses at both relatively low and relatively high temperatures includes a substantially pure silica core (12) and a hydrogen retarding layer (18). The hydrogen retarding coating may be made of carbon, metal, or silicon nitride. The fiber may also include a cladding layer (14), a second silica layer (16), and a protective outer sheath (20). |
