Abstract
PURPOSE:To efficiently produce an optical fiber with high dimensional accuracy by making a glass tube thin while introducing core glass made thin into the tube. CONSTITUTION:Core glass 3 as core held by core glass feeder 1 is melted in heating furnace 2, made thin, and introduced into the hollow part of glass tube 5 as clad held by glass tube feeder 4. Tube 4 is then melted in heating furnace 6, made thin together with glass 3 in one, and wound round coiler 8 through precoat forming unit 7.
