More Information
Summary:Provided are a manufacturing method of an optical fiber base material and an optical fiber base material manufactured in the manufacturing method, the manufacturing method including: a process of combining at least two core base materials by fusion-bonding to produce a single core base material; a process of fusion-bonding a pair of dummy glass rods and at both ends of the core base material to produce a starting glass rod; a process of depositing, at an outer surface of the starting glass rod, glass particles generated by flame hydrolysis, to produce a porous base material ; and a process of sintering and vitrifying, into transparent glass, the porous base material , to produce an optical fiber base material that includes a core portion and a clad portion.
