Description

  The present invention relates to an optical fiber cable wiring fixture, and more particularly to an optical fiber cable wiring fixture that is attached to an optical fiber cable and that fixes the optical fiber cable in place.

  At present, an optical fiber is widely used as a transmission medium for transmitting a large amount of information, thereby further increasing the speed of information transmission. An optical fiber has many advantages such as that the transmission speed is not easily deteriorated. Therefore, it is widely used from short-distance communication such as indoors and premises to long-distance communication connecting cities. In particular, when an optical fiber is used indoors or on the premises, an optical fiber cable in which the outside of the optical fiber is covered with a covering member such as vinyl is used.

An optical fiber is composed of a core part that transmits light and a clad part that covers the outer periphery of the core part, and is roughly classified into a silica-based optical fiber and a plastic optical fiber (hereinafter referred to as POF) depending on the type of constituent materials. When connecting electronic devices using an optical fiber, an optical fiber cable in which an optical fiber strand is covered with a covering member is often used, which may cause the optical fiber strand to break. It is prevented. Further, in some of such optical fiber cables, in order to further increase the tensile strength in the axial direction, the tensile strength wire is covered with a covering member together with the optical fiber.
