Abstract

Disclosed is an optical fiber composite power cable having a loose-tube-type optical fiber impregnated therein, wherein the optical fibers are installed in a loose tube made of metal to prevent lateral pressure from being imposed on the optical fibers by the metal conductors, even when tensile force or bending force is applied to the cable.

Claims

1. An optical fiber composite power cable including optical fibers and metal conductors, the improvement comprising a loose-tube containing the optical fibers therein, said loose-tube being made of metal to prevent lateral pressure from being imposed on the optical fibers by the metal conductors when tensile force or bending force is applied to the cable.

2. The optical fiber composite power cable as set forth in claim 1,

wherein the loose tube is made of stainless steel.
