Title:
OPTICAL FIBER WINDING METHOD AND OPTICAL FIBER
Document Type and Number:
Japanese Patent JP2017024814
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical fiber winding method in which tension control is facilitated, winding collapse hardly occurs in optical fiber transport, and increase of transmission loss can be suppressed.SOLUTION: A winding method of an optical fiber 10 is a method for winding the optical fiber 10 which is mainly formed of quartz glass to a bobbin 20, in which a winding tension of the optical fiber 10 is constant and in a range of 30 g or higher and 70 g or lower, and a ratio V/S of an actual volume V of the optical fiber 10 determined based on a cross section and length of the wound optical fiber 10, with respect to a volume S on a wound part 11 of the optical fiber 10 determined based on a winding radius t of the optical fiber 10 wound to a trunk 20a of the bobbin 20 and a radius r and a width w of the trunk 20a, becomes 58% or higher and 79% or lower, by setting a winding condition.SELECTED DRAWING: Figure 1
