Optical fiber processing apparatus an process method

Abstract

There is provide an optical fiber processing apparatus and a process method capable of shortening time required for replacing an atmosphere in a treatment container with inert gas and filling with deuterium and of restraining an amount used of expensive deuterium. An optical fiber processing apparatus includes a plurality of containers 1 for processing optical fiber that are spatially coupled by piping, each treatment container 1 including a treatment chamber that can be sealed and accommodate one or more bobbins 4 on which fiber to be processed is wound, in which the treatment chamber is supplied with treatment gas, and the optical fiber is processed by the gas. The treatment gas is deuterium or gas including the deuterium.
