METHOD FOR LEADING IN CABLE AND PROTECTOR FOR USE THEREIN

摘要

Disclosed is a countermeasure being taken against the abnormal pulling action of a cable by simple work without using an expensive tool. A method for branching a branch line cable (10), having an optical-fiber main line (11) for transmitting optical signals and a supporting-wire (12) attached thereto, from a trunk line cable system and leading the branch line cable into a building. A main fixing portion (30) for fixing the branch line cable (10) to the outer wall (20) at a first position from the trunk line cable system is formed, a part of the supporting-wire (12) is removed from a portion of the cable (10) extending between the main fixing portion (30) and the cable service entrance (21) of the building, the portion (10p) of the cable where only the optical fiber main line (11) remains due to the removal is wound up in the shape of a ring to form a wound portion (11r), and a protector (50) for passing over the wound portion of the cable and holding the wound portion is fixed to the wound portion (11r). The protector (50) is arranged such that the portion of the cable, abutting against the edge of the protector (50), can be cut by the edge preferentially to other portions of the cable when the cable (10) is pulled from the building in the direction of the trunk cable system.
