The hydroxyl loss increase characteristics for antimony oxide-doped silica fibers were investigated to ensure long-term reliability. The loss increase was measured for non-irradiated and γ-irradiated fibers with hydrogen molecule diffusion and heat treatments. The loss increase characteristics for these experiments were similar to those for germanium oxide-doped silica fibers.
