線入り平型光／電源線複合コード。[Scope of Claim for Utility Model Registration] (1) In an optical power line composite cord in which a power line and an optical fiber core wire are commonly coated, power lines 21 and 22 are arranged at both ends of a flat shape, and a grounding cable for communication equipment is provided. The wire 1 is arranged in the center, the power wires 21 and 22 and the ground wire 1 are commonly connected by plastic connecting parts 41 and 42, and gaps 51 and 52 are formed in a part of each of the plastic connecting parts 41 and 42, respectively. An optical fiber core 61 is provided in the gaps 51 and 52,
A flat type optical/power line composite cord with a grounding wire, characterized by having a structure in which a 62 is built in loosely with extra length. (2) The remaining length of the optical fiber core wires 61 and 62 built loosely in the gaps 51 and 52 is the length when the flat optical/power line composite cord with ground wire is bent within a plane with an allowable bending radius. A flat optical/power line composite cord with a grounding wire according to claim 1, characterized in that the cord has a slack greater than the elongation strain applied to the optical fiber core wire.
