CLAD MOLD FOR PRODUCING PARENT MATERIAL OF OPTICAL FIBER BY MELTING METHOD AND METHOD FOR PRODUCING PARENT MATERIAL OF OPTICAL FIBER USING THE MOLD |
摘要 |
PURPOSE: Provided is a clad mold for producing optical fiber by a melting method which can be prepared economically in a simple process, and thereby it is possible to prevent a parent material of optical fiber from being contaminated by impurities and deteriorated in its quality. CONSTITUTION: The mold of clad(10) for producing a parent material of optical fiber comprises a clad mold(11) of a pipe shape having an end closed, a predetermined length and an inner diameter corresponding to a diameter of a clad; and a cylindrical core rod(12) attached to the closed end of the clad mold(11) in the same axis as the clad mold(11) and having a predetermined length and an outer diameter corresponding to a diameter of a core to be formed. The clad mold is prepared by (i) pouring melted glass to a hollow of the mold of clad(10), followed by solidifying the glass to form a clad; (ii) removing the clad mold(11); (iii) removing the core rod(12); and (iv) inserting a core rod into a hollow formed by removing the core rod in the step (iii). |
