Abstract
An apparatus that exposes only a selected portion of a length of optical fiber to a hydrogen atmosphere loading process. The apparatus includes a loading chamber that encloses at least the selected portion of the optical fiber and contains a hydrogen hydrogen atmosphere. At least one heating element regionally heats the hydrogen atmosphere surrounding the selected portion. The heating element may heat the hydrogen atmosphere to a temperature of at least 250° C.
