IPC: C03B37/018
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing an optical fiber preform capable of producing the homogeneous optical fiber prefomt with good accuracy. SOLUTION: This process produces the optical fiber preform by depositing glass particulate on the outer periphery of a glass rod to form a glass particulate deposit and heating this deposit to make the deposit transparent. The final clad/core magnification is designed to meet optical fiber characteristics from the refractive index distribution of a core preform or the glass rod in this process. The weights of the glass particulates to be deposited on the effective part and non-effective part of the glass particulate deposit are estimated from this designed clad/core magnification, the outside diameter of the glass rod and an empirically determined calculation equation. The glass particulates are deposited until the deposited weight of the glass particulates on the glass rod is attained to total weight of the estimated weight.
