Title: Optical fiber preform and method for manufacturing the same
Inventor: KOMURA YUKIO
IPC: C03B37/014
Filed: 2001-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a large-size optical fiber preform which can easily be manufactured and in which an effective drawing region to produce a proper optical fiber can be increased. SOLUTION: A shoulder part 12 extending from the center part M of the preform is formed in a base end region K which is the end side for drawing.

Thereby, a stretching process after the sintering process can be eliminated so simplify the manufacturing processes. Conventionally, in a period near to the end of drawing in the drawing process, stable drawing can not be carried out because of disturbance generating in the gas flowing in the furnace of a drawing device.  By forming the shoulder part 12, a narrow space is formed between the inner wall of the furnace and the optical fiber preform and the space rectifies the gas flow, which results in stable drawing even in the period near the end of drawing.
