Abstract
PURPOSE:To obtain stable optical fiber with low loss by bundling bar-like materials annularly so that their outer peripheries come into contact mutually, and by elongating them, lengthwise by heating them from their peripheral sides while a space having small thermal capacity is provided in the center part. CONSTITUTION:Bar-like material 1a-1f of quartz glass are bundled together annularly in contact, and in their center, a space 3 having small thermal capacity is provided. Those bundled materials 1a-1f are held by the material holding tool A of a spinning device and inserted into the cylindrical heating furnace B, such as a high- frequency induction furnace, of the spinning device from the lower ends of the materials for heating and softening, and the lower ends of softened materials 1a-1f are drawn at a high speed by a drawing machine to elongate each material. Thus, low- loss and stable multiple optical fiber is obtained.
