Problems solved by technology

[0004] In the case of transporting a bobbin wound with an optical fiber using the package used in Patent Document 1, if the winding tension of the optical fiber is low when winding the optical fiber onto the bobbin, the fiber may be damaged due to vibration or shock during transportation of the optical fiber. Fiber unwinding occurs
In addition, if the winding tension of the fiber is increased to prevent the fiber from being unwound, the transmission loss increases due to the side pressure on the fiber.

Embodiment

[0042] (1) Evaluation of unwinding

[0043] Eight bobbins 11 on which optical fibers 10 of a predetermined length were wound were accommodated in the packing box 20 , and the packing box 20 was dropped from a height of 300 mm, and unwinding of the optical fibers 10 in the packing box 20 at this time was evaluated. Prepare T / P as shown in Table 1 2 With from 0.2N / mm 2 to 7.0N / mm 2 The spools 11 of the 6 values ​​were evaluated for the unwinding of the optical fiber 10 after the drop test of each spool.

[0044]Specifically, the bobbin 11 after the drop test was confirmed by visual observation and contact inspection, and whether unwinding of the optical fiber 10 occurred was evaluated. In Table 1, "○" indicates that no unwinding was found through visual inspection and contact inspection, and "△" indicates that there is no problem with visual inspection, but if the optical fiber 10 wound on the bobbin 11 is touched by hand, the winding of the optical fiber 10 The winding is s...

Abstract

The invention provides an optical fiber winding method, a reeled optical fiber, and an optical fiber transport method. The fiber winding method can prevent a fiber reel from releasing when the transmission loss of the fiber is reduced at the same time. When a fiber (10) having a diameter of about 250 [mu]m is being wound on a bobbin (11) and a winding tension is set as T (N) and a transverse pitch is set as P (mm), the optical fiber (10) is wound on the bobbin (11) with T / P2 larger than or equal to 0.5 N / mm2 and smaller than or equal to 6.3 N / mm2.

Description

technical field [0001] The invention relates to an optical fiber winding method, a reel optical fiber and an optical fiber transportation method. Background technique [0002] Conventionally, when optical fiber is transported, the bobbin on which the optical fiber is wound is housed in a cardboard package and transported. As this package body, the structure shown in patent document 1 can be used, for example. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 10-324370 [0004] In the case of transporting a bobbin wound with an optical fiber using the package used in Patent Document 1, if the winding tension of the optical fiber is low when winding the optical fiber onto the bobbin, the fiber may be damaged due to vibration or shock during transportation of the optical fiber. Fiber unwinding occurs. In addition, if the winding tension of the optical fiber is increased in order to prevent the optical fiber from being unwound, the transmission loss increa...
