Abstract
The utility model discloses an interlocking armored remote photoelectric composite cable. A central reinforcing element is arranged coaxially with the composite photoelectric cable. Optical cable units, electric cable units and filling material are arranged around the central reinforcing element and are stranded into an integrated stranded body. A water resisting layer vertically wraps the stranded body, an interlocking armored layer coats the water resisting layer, and the outer sheath extrudes the interlocking armored layer. Therefore, the optical cable units and the electric cable units are compounded in one cable. Dual functions of optical fiber communication and remote power supply between a near-end baseband unit and a remote radio frequency unit are achieved, power taking and location of the remote radio frequency unit are facilitated, and power facility construction, operation and maintenance costs of base stations are greatly reduced. The interlocking armored structure design enables the composite cable to have high flexibility, smaller radius of bending, and tensile and compressive properties. The interlocking armored remote photoelectric composite cable is applicable to a variety of laying modes such as horizontal laying, vertical laying, bridge-type laying and pipe-through laying, and has higher flexibility.
