Abstract
Official abstract text for this publication.
A manufacturing method for an optical fiber preform includes forming a porous material made of fine silica glass particles surrounding a plurality of glass rods; and sintering the porous material, wherein the forming the porous material includes forming the porous material such that two or more of the plurality of glass rods protrude from the porous material, and the sintering includes supporting end portions of protruding sides of the two or more protruding glass rods collectively with a support jig, and performing the sintering. With this, a reduction in manufacturing yield is suppressed.
First claim
Opening claim text (preview).
1 : A manufacturing method for an optical fiber preform, the method comprising: forming a porous material made of fine silica glass particles surrounding a plurality of glass rods; and sintering the porous material, wherein the forming the porous material includes forming the porous material such that two or more of the plurality of glass rods protrude from the porous material, and the sintering includes supporting end portions of protruding sides of the two or more protruding glass rods collectively with a support jig, and performing the sintering. 2 : The manufacturing method for the optical fiber preform according to claim 1 , wherein the support jig is configured to allow the supported glass rods to move in a direction that approaches the center axis of the porous material. 3 : The manufacturing method for the optical fiber preform according to claim 1 , wherein the support jig is configured to allow the supported glass rods to be tilted in a direction that approaches the center axis of the porous material. 4 : A manufacturing method for optical fiber, the method comprising drawing an optical fiber from an optical fiber preform manufactured by the manufacturing method according to claim 1 .
