Abstract

PURPOSE:To inexpensively obtain a high quality optical fiber by converting glass starting material gases into glass soot in a flame cone to form porous glass on the tip of a starting member and transparently vitrifying the glass by the heat of the cone. CONSTITUTION:Glass starting materials fed into oxyhydrogen burner 21 cause oxidation reaction in flame 22, generating glass soot. In the early stage this soot is blown on the tip of starting member 5 entering the inside of flame cone 23, and it is deposited to form porous glass 25. By pulling up member 5 in synchronism with the forming speed, glass 25 is passed through cone 23 which is a very high temp. region. At this time, glass 25 is freed of bubbles and made transparent. It is fed upward and then converted into optical fiber base material 26 of transparent glass. Thus, by applying the heat source for causing the glass synthesis reaction to the transparent vitrification, a high quality optical fiber is manufactured at a low cost.
