OPTICAL AND POWER COMPOSITE CABLE

摘要

PURPOSE: An optical power composite cable is provided to minimize the transmission loss of an optical communications by improving durability against heat, which is generated from a power line, and minimizing an influence due to a lateral pressure which is applied to an optical fiber. CONSTITUTION: A power line(110) consists of a central conductor(111) which is made of a wire conducting conductor and an insulation coating layer(112). The isolation coating layer is molded by extrusion in the outer circumference of the central conductor. An optical fiber unit(120) includes an optical fiber(121) and a tube(122) which covers the optical fiber. A cable sheath(130) is included to be the shape that surrounds the power line and the optical fiber unit. A braid shielding layer(140) blocks an electromagnetic field, which is generated in the central conductor of the power line, from the outside.
