Abstract

PURPOSE:To manufacture an optical fiber with low OH content and low loss by passing a porous base material for the fiber through a heating furnace internally provided with a muffle tube made of quartz to dehydrate and sinter the material. CONSTITUTION:A porous base material 1 for an optical fiber deposited on the tip of a rodlike substrate 2 is passed through a muffle tube 5 made of quartz in an electric furnace 3. A dehydrating gas such as He, SOCl2 or Cl2 is fed from an inlet 8, gaseous Ar is fed from an inlet 9 to form an inert atmosphere, and the material 1 is dehydrated and sintered by heating with a carbon heater 4. The material is then spun to obtain an optical fiber with low loss.
