Description

The present invention relates to an external communication transmission path and a comprehensive signal transmission system provided in a building.

  In recent years, with the spread of the Internet and the like, a high-speed and large-capacity communication transmission path is becoming an essential requirement. In addition, the necessity is increasing in small and medium-sized office buildings or apartment houses, which conventionally did not require such a large-capacity communication transmission line. These communication transmission paths are often configured by laying optical cables for the purpose of using a LAN (Local Area Network) or the like.

  FIG. 6 shows a communication transmission line network using optical cables. Each backbone station 107 is connected by the backbone optical cable 101 to form a backbone optical network. Each backbone station 107 is provided with a backbone distributor 108 and branches the backbone optical cable 101 to each trunk optical cable 102. Each trunk optical cable 102 branches the branch optical cable 103 toward each building 114 at a branching point 109. Each branch line optical cable 103 is connected to the main distribution board 110 of each building 114. The main distribution board 110 is connected to a distributor 111 on each floor of the building by an indoor optical cable 104, and is connected to each terminal 112 by an individual optical cable 106 from each distributor. When connecting to each individual house 117, the optical fiber is connected from the branch point 109 of the trunk optical cable 102 to the connector 113 by the optical drop cable 116, and from here to the individual terminal 112 by the indoor individual optical cable 106.

  The backbone optical cable 101, the trunk optical cable 102, the branch optical cable 103, and the indoor optical cable 104 are a plurality of large-capacity or small-medium capacity lines. Therefore, as shown in FIG. A tape slot type cable 120 is used in which the wire 121 is accommodated in the slot 126 of the grooved spacer 122 and the outer surface is covered with a holding roll 124 and a polyethylene sheath 125. In addition, as the individual optical cable 106, an indoor cable 130 is used in which one tape core 121 is covered with a polyethylene sheath 125 as shown in FIG. In order to protect a very fragile optical fiber made of quartz glass, the tape core 121 is formed by arranging a plurality of cores covered with an ultraviolet curable resin and further covered with an ultraviolet curable resin. Further, a tension member 123 made of steel wire is embedded in both the tape slot type cable and the indoor cable in order to prevent the optical fiber from being damaged due to tension when the optical cable is laid.

  Due to the characteristics of the optical fiber, if it bends, the propagation characteristics deteriorate or breakage occurs. Therefore, a minimum bending radius is defined for each cable. A tape slot type cable having a large capacity of several hundred cores used for the trunk optical cable 102 has a minimum bending radius of 300 to 600 mm, a small and medium capacity having several tens of cores used for the branch optical cable 103 and the indoor optical cable 104. The minimum bending radius of the tape slot type cable is 100 to 200 mm, and the single-core indoor cable used for the individual optical cable 106 is about 15 to 30 mm. For this reason, the indoor optical cable 104 is installed on a dedicated straight vertical wiring path, and the individual optical cable 106 from the distributor is installed in a bent pipe to each piece.

  Old buildings, small and medium-sized office buildings, or apartment buildings are not designed to install high-speed, large-capacity communication transmission lines using optical fiber cables. There is not enough space to install a path, and a situation has arisen where a high-speed and large-capacity communication transmission path using an optical fiber cable cannot be installed. When there are several bent wiring paths, it is conceivable to arrange the distributor 111 near the main distribution board 110 and to lay the individual optical cable 106 from there to each terminal, but in the case of a small number of cables, Even if it is possible, it is difficult to install such a large-scale individual optical cable in buildings and apartment buildings with hundreds of terminals, and it is practically a high-speed and large-capacity communication transmission line using optical fiber cables. It was very difficult to lay.

  Therefore, when an optical cable is laid in such a building, a hole is made in the floor of each floor of the building, and a vertical wiring path for laying the optical cable in the vertical direction of the building is provided. For that purpose, the floor of each floor is first inspected by non-destructive inspection with X-rays, and the position of electrical cables and pipes embedded in the floor is preliminarily investigated, and holes are drilled in the floor avoiding those places. Then, a method of installing a straight vertical wiring pipe in the hole and laying an optical cable in the pipe is performed.

  However, drilling holes on the floors of each floor of the building has a problem that the construction period and costs increase due to the need for pre-investigation by non-destructive inspection and large-scale construction due to the thick floor. . In addition, since it is necessary to install the optical fiber cable so as not to apply tension to the optical fiber, it is necessary to provide a lot of support in the vertical wiring path, resulting in an increase in work period and cost.

  Therefore, the object of the present invention is to reduce the number of supports of the vertical wiring path without carrying out large-scale construction such as opening the floor in the building, and to install the optical cable in a short time and at low cost to the residents of the building. Another object of the present invention is to provide a building external communication transmission path that can be laid.
