Inventor: SUZUKI TOSHIYUKI
IPC: C03B37/014
Filed: 2002-03-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for producing an optical fiber preform by depositing soot generated by a flame reaction, particularly in which the time required from the flame polishing of the surface of a starting preform to the start of glass particle deposition is shortened.  <P>SOLUTION: This production method for the optical fiber preform includes moving a polishing flame burner to be moved prior to a soot depositing flame burner at nearly the same speed as that of the latter in a process for depositing the soot obtained from the flame burners 21 and 22 on the outer periphery of a target 10. Thereby, after the movement start of the polishing flame burner, the movement of the soot depositing flame burner can be started without setting a long spare time interval (standby time). Therefore, the time required for production can be shortened, thus enhancing productivity.  <P>COPYRIGHT: (C)2003,JPO
