Treatment Method For Optical Fiber

Abstract: A treatment method for an optical fiber including accommodating an optical fiber inside a treatment chamber, introducing a deuterium containing gas into the  treatment chamber and in a deuterium treatment Step exposing the Optical fiber to atmosphere at the dcuterium coataining gas. In the deuterium treatment step, a deuterium concentration D in the treatment chamber during the deuterium treatment is calculated from an initial value A of a deuterium concentration in the deuterium containing gas inside the treatment chamber, a concentration D of oxygen is an ambient atmosphere of the treatment chamber, and a concentration C of oxygen in the deuterium containing gas inside the treatment chamber, and the deuterium concentration in the treatment chamber is controlled based on the deuterium concentration D calculated. Other gases such as hydrogen containing gas or nitrogen containing gas may also be used according to the invention,
