Optical network composite cable

Abstract

The utility model discloses an optical network composite cable, which comprises a network cable outer insulating layer, an inner support is arranged in the network cable outer insulating layer, the inner support is of a support structure with a cross-shaped cross section, the inner support divides the interior of the network cable outer insulating layer into four cavities, a pair of network cables is arranged in each cavity, a first inner insulating layer is wrapped on the periphery of the network cables, and a second inner insulating layer is wrapped on the periphery of the first inner insulating layer. Each pair of network cables are mutually twisted and stacked to form a twisted pair; a light-guide fiber outer insulating layer is attached to one side wall of the network cable outer insulating layer, polyester yarn is arranged on the inner wall of the light-guide fiber outer insulating layer, a pair of light-guide fibers is arranged in the polyester yarn, and a second inner insulating layer wraps the peripheries of the light-guide fibers. The optical network composite cable is formed by combining the optical fibers and the network cables, upgrading and updating along with network upgrading and development can be facilitated, the network cables can be used as a main body, the optical fibers can be reserved for standby application, the optical fibers can be used as optical fiber parts of the optical network composite cable in special application scenes, wiring troubles caused by the fact that the network cables are replaced by the optical fibers can be avoided, and the optical network composite cable is convenient to use. And the later wiring upgrading cost is reduced.
