Paper Abstract

Optical losses induced in fibers at 300oC and in hydrogen atmosphere were studied. A non-linear dependence of hydrogen penetration through the carbon coating on hydrogen pressure was observed. It was demonstrated that carbon coating could not defend the fiber from hydrogen penetration for a long time period. At some time, the hydrogen presence in the fiber core resulted in high optical losses in all spectral range in the case of Ge-doped fibers. It was found that the short-wavelength loss edge (SWE) in a Ge-doped fiber co-doped with a small amount of phosphorus was significantly smaller than that in Ge-doped fibers without co-doping. Nevertheless, P-codoping effect did not decrease optical losses related with SWE completely.
