Abstract

PURPOSE:To prevent formation of air bubbles between a core and clad and to enable the core diameter to be easily controlled by melt-softening glass material, as core glass, having a m.p. below the softening temp. of clad glass in a clad glass tube at a specified temp. followed by spinning with heating. CONSTITUTION:Clad glass tube 2 is filled with glass material as core glass 1 which material melts at a working temp. about 100 deg.C or more below the softening temp. of tube 2. Next glass 1 is melt-softened in core glass melting furnace 3 at a temp. about 50 deg.C or more below the softening temp. of tube 2, and the softened core glass is adhered to tube 2 to form a preform. This preform is put into spinning furnace 4, heated to a temp. above the softening temp. of tube 2, softened, and spinned into fiber 5 at a predetermined speed. By this method slippage of the core glass in the preform is prevented, and connection between fivers and of fiber to a coupler, etc. is furthar faciliated compared to conventional fiber.
