非接触方向転換器、及び、光ファイバの製造方法

摘要

PROBLEM TO BE SOLVED: To provide a non-contact direction converter for converting an optical fiber running direction in a non-contact manner, capable of reducing the contact frequency of the optical fiber to the side surfaces of a groove guiding the optical fiber.;SOLUTION: A bottom surface ejection port (1043a) is formed on the bottom surface of a guide groove (1043) guiding a bare fiber (11), and a side surface ejection port (1043b) is formed in the side surface. The flow rate of a fluid flowing from the bottom surface ejection port (1043a) is smaller than that of a fluid flowing from the side surface ejection port (1043b).;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2019,JPO&INPIT
