Description

[0001]
BACKGROUND OF THE INVENTION
The present invention provides an optical cable for fixing an optical cable and an optical cable connector when an optical cable having a core wire and a covering member that covers the core wire in a state in which the tip end portion is exposed is connected to the optical cable connector. The present invention relates to a fixture and an optical cable fixing method.
[0002]
[Prior art]
Examples of conventional optical cable connectors include a simple assembly type SC connector and an MT-RJ connector provided with a mechanical splice mechanism (see, for example, Patent Document 1).
[0003]
FIG. 5 is a diagram showing an example of the optical cable connector as described above. In this figure, the core wire 103a is exposed by removing the covering member 102 for protecting the core wire 103a of the optical cable 101. The case where the core wire 103a is connected to the optical cable connector 100 is shown.
[0004]
In this way, when connecting the core 103a to the optical cable connector 100, the connection work between the optical cable connector 100 and the core 103a is re-executed, and the layout of the optical cable connector 100 and other optical components can be changed. A cord extra length portion 103b, which is an extra length portion, is provided.
