Abstract

Disclosed is a method of manufacturing an air blown optical fiber unit for prevention of characteristic deterioration of a coating layer, and a gas chamber used therein. This method includes coating a first coating resin on a surface of an optical fiber bundle; introducing the optical fiber bundle coated with the first coating resin into a first curing chamber under inert gas environment and curing the first coating resin to form a first coating layer, coating a second coating resin on a surface of the first coating layer; attaching beads to a surface of the second coating layer; and introducing the optical fiber bundle having the beads attached thereto into a second curing chamber under inert gas environment and curing the second coating resin to form a second coating layer. This method may improve stiffness of the coating layer by intercepting introduction of impurities during the coating layer forming process.
