The present invention provides a method and apparatus for manufacturing a optical fiber that the bare optical fiber can be stably levitated.
A spinning step of forming a bare optical fiber 3 An optical fiber preform was melt-spun, and a coating step of providing a coating layer made of resin on the outer circumference of the bare optical fiber 3, to cure the coating layer to provide a manufacturing method of the optical fiber and a curing step of obtaining an optical fiber wire. At any position from the spinning step to the coating step, to convert the direction of the bare optical fiber 3 by the direction converter 201. Direction converter 201, has a guide groove 21 for guiding the bare optical fiber 3. The guide groove 21, air outlet 22 of the fluid levitate the bare optical fiber 3 is formed along the guide groove 21. Introduced from the outlet port 22 the fluid in the guide groove 21 to levitate the bare optical fiber 3, in which case, the Reynolds number of the fluid in the range of 1200-3500.
