Description

The present invention is a fictitious plan that uses an extra cable length of an optical cable or a metal cable in a communication circuit such as information communication wired outdoors such as a house, an office, a factory, and other buildings of an ordinary house in an urban area. The present invention relates to a cable extra length gripping system to be previously stored.

In general, in an aerial network using cables in urban areas and the like, multiple cables can be routed by placing a steel stranded wire between utility poles and passing the spiral hanger so that no cables are used in the spiral hanger. It is a construction method that can also lay strips. (For example, see Patent Document 1)
This method could only branch after using the extra wire length in the aerial closure without taking up the extra cable length.
In this way, since the overhead wiring system is installed without taking up the extra cable length, relocation work such as line borrowing and cable allocation is required when troubles occur, and the connection work takes a long time (period). A lot of workers are required and the cost is high, and if the construction site is a road, long traffic regulation is required, construction day regulation and traffic congestion are also expected, and there are also problems of connection points and wiring points At the connection point such as post-branch or drop in the cable, the extra length of the lower core cannot be obtained, and the lower or main line cannot be returned, which makes it difficult to regenerate the lower core, leading to a decrease in the optical fiber operating rate. The torn cable generated during laying requires industrial waste treatment, and the costs for packaging, transportation, dismantling, disposal, etc. are enormous.
In particular, when an aerial network is interfered in an urban area as in recent years, the conventional method requires that the cable be replaced when the trouble of the utility pole is relocated, and that there is not enough extra cable length due to rear branching. In order to solve such problems, it is necessary to prepare the extra length of the cable in advance.
In this way, there are a lot of cable replacement work due to CP pillar renewal and obstacle relocation work, and if enough extra cable length is taken for this countermeasure, wrapping the cable around the connection cable extra length storage Although the cable extra length is wound and stored with a string at the end of the utility pole as in Patent Document 1, or the cable extra length is formed by a support member provided radially as in Patent Document 2, the cable extra length is A method of winding and storing cables to enable cable transfer is known.
