Abstract
An optical-fiber-drawing method, employed during the manufacturing of an optical fiber from an optical-fiber perform, includes: a step of heating an end of the optical fiber preform to thereby melt and draw the end of the optical-fiber preform; a first spin-forming step, in which a predetermined spin is given to the optical-fiber preform in a predetermined direction that is perpendicular to a direction in which the optical-fiber preform is drawn; and, a second spin-forming step, in which the optical-fiber preform is further twisted according to a predetermined spin function.
Claims5
A method for drawing an optical fiber from an optical-fiber preform, the method comprising:
- a step of heating one end of the optical-fiber preform for melting and drawing the end of the optical-fiber preform;
- a first spin-forming step for applying a first predetermined spin to the optical-fiber preform in a first predetermined direction that is perpendicular to a direction in which the optical-fiber preform is drawn;
- and,
- a second spin-forming step for applying a second predetermined spin to the optical-fiber preform in a second predetermined direction according to a predefined spin function.
