Title: Production of base material for optical fiber
Inventor: ITO HIDEAKI
IPC: C03B37/012
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To produce a preform for an optical fiber while preventing generation of air bubbles and eccentricity of a core by integrating a glass pipe with a glass rod and drawing them at the same time. SOLUTION: A glass rod 2 as a core or a core and clad is inserted into a glass pipe 1 as a clad to integrate them successively in the axial direction by reducing the diameter of the glass pipe 1 while heating them by a heater and reducing the pressure inside the glass pipe 1. An auxiliary rod 21 having a small diameter and long length is bonded to the end of the glass rod on the integration-terminated side to integrate them in such a state that the distance L between the end of the glass rod and a fixed position of the auxiliary rod is made large. The end of the glass rod on the integration-terminal side becomes movable in the plane crossing the axis at right angles and such a self-aligning effect that the glass rod moves toward the axial center of the glass pipe is obtained by reducing the diameter of the glass pipe, thus preventing the eccentricity of the core.
