Abstract
An optical fiber processing apparatus comprises reactors (and) that accommodate optical fiber, a single suction pump () having an intake port () and an outlet port (), a storage chamber () into which deuterium containing gas is delivered, and a circuit portion () including a plurality of valves disposed on a plurality of passages connecting the reactors, the suction pump and the storage chamber. The circuit portion includes a first channel for returning deuterium containing gas inside a reactor chamber to the storage chamber, a second channel for delivering air to the reactor chamber thereby rendering the pressure inside the reactor chamber atmospheric pressure, a third channel for decompression of the reactor chamber and a fourth channel for supplying deuterium containing gas in the storage chamber into the reactor chamber.
