title: Temperature dependence of the hydrogen-diffusion constant in optical fibers.
abstract: The dependence on hydrogen pressure and temperature of the increase in absorption loss is described for a singlemode optical fiber. The hydrogen-diffusion constant for various temperatures and the activation energy in silicabased optical fibers are obtained.
