Cable wiring method

Abstract

The invention provides a cable wiring method so as to easily branch and wire an optical cable. An optical cable wiring method of the present disclosure performs: preparing a plurality of cable supply sources that supply optical cables; forming a cable bundle by pulling out the optical cables from the plurality of cable supply sources, respectively, and bundling the plurality of optical cables; erecting the plurality of optical cables from a utility pole serving as a starting point of a first wiring path to a branching point on the first wiring path by inserting the cable bundle through a cable hanger laid on a suspension line erected between utility poles; dividing the plurality of optical cables constituting the cable bundle into a first group and a second group at the branching point; erecting the optical cables belonging to the first group along the first wiring path ahead of the branching point; and erecting the optical cable belonging to the second group along a second wiring path branched off from the first wiring path.

Description

technical field [0001] The present invention relates to a cable routing method. Background technique [0002] When laying the optical cable from the baseline point (starting point) to the landing point, there are cases where the optical cable is erected between electric posts on the wiring route. In the case of erecting a non-self-supporting type optical cable having no support wire, the optical cable is erected on the suspension wires erected between electric poles via a cable hanger using a bucket truck. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2007-304549 [0004] There are cases where a branch cable branched from an optical cable is laid at a branch point of a wiring path. In this case, it is necessary to perform branching work such as installing a splicer on the optical cable at the branching point and installing a branch cable on the optical cable. However, since overhead branch work can be costly, it is desirable to reduce overhead bra...

Problems solved by technology

However, in this case, the distance from the baseline point to the branch point needs to be grasped in advance, and the use place of the optical cable is limited (also, it is difficult to lay the optical cable with the branch cable installed in advance).
