摘要： When a GRIN lens fiber is drawn from a preform, control of a fiber diameter is improved in order to increase a production yield of the GRIN lens fiber having a fiber diameter within a desired range. The problem is solved by controlling the drawing speed using a fiber diameter c, which is obtained by correcting a fiber diameter a using the fiber diameter b and a fiber diameter ±. The fiber diameter a is measured using a diameter measuring instrument A that measures an outer diameter of the GRIN lens fiber, which is being elongated inside a heating furnace, the fiber diameter b is measured using a diameter measuring instrument B that measures an outer diameter of the GRIN lens fiber outside the heating furnace, and the fiber diameter ± is a value of the fiber diameter a measured a specified period of time T earlier.

摘要： PROBLEM TO BE SOLVED: To provide a method for production of an optical fiber capable of easily inhibiting both fluctuation of longitudinal vacancy diameter and fiber curling.SOLUTION: The method includes producing a silica-based optical fiber having voids extending in an axial direction. The optical fiber base material in which the maximum deviation of specific refractive index in an outer layer is less than 0.01% is drawn. When the external diameter of the optical fiber base material is defined as 2R, the external layer becomes a region from R/2 to R in the distance in a radial direction from a central axis. In the optical fiber base material, the vacancy extending in the axial direction is provided in the region from the central axis to the radial direction distance R/2, and the optical fiber is produced by drawing such optical fiber base material. The glass tension when drawing is made to be ≥100 g but ≤300 g.
