Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0016] Such as figure 1 As shown, a photoelectric composite cable for access network, which includes PE outer sheath 1, isolation belt 2, composite belt 3, feeder 4, central reinforcement with cushion 5, ointment 6, insulating cushion 7, filling rope 8. Optical fiber 9, feeder line 4, insulating cushion 7, and optical fiber 9 are uniformly twisted around the central strength member containing cushion 5 as the center to form an optical and electrical composite cable core, and are sequentially covered with isolation tape 2 and composite tape from the inside to the outside 3. PE outer protection 1, a filling rope 8 is arranged inside the isolation belt 2, and the inside of the isolation belt 2 is filled with ointment 6.

[0017] The feeder 4 is made of twisted strands of pure c...

Abstract

The invention relates to a photoelectric composite cable for an access network. The photoelectric composite cable comprises a PE outer sheath (1), an isolation strip (2), a composite strip (3), feed wires (4), a center reinforcement mat-contained layer (5), ointment (6), insulation cushion layers (7), a filling rope (8) and fibers (9), wherein the feed wires (4), the insulation cushion layers (7), the fiber (9) are uniformly distributed and stranded into a photoelectric composite cable core by taking the center reinforcement mat-contained layer (5) as a center, the photoelectric composite cable core is sequentially wrapped by the isolation strip (2), the composite strip (3) and the PE outer sheath (1) from inside to outside, and the isolation strip (2) is internally provided with the filling rope (8). The photoelectric composite cable is advantaged in that: the photoelectric composite cable has properties of small outer diameter, light weight, small occupation space, excellent bending performance, good pressure resistance performance and convenient construction; construction cost and pipeline resources are saved because of construction convenience; the fibers, power transmission copper wires and copper signal wires are integrated into one body, so problems of broadband access, electricity utilization of equipment and emergency signal transmission can be solved simultaneously.

Description

technical field [0001] The invention relates to a cable, in particular to a photoelectric composite cable for an access network. Background technique [0002] With the development of the global telecommunication network in the direction of digitalization, broadband and intelligence, the construction of optical fiber user access network with large-capacity optical cable as the main transmission medium is accelerating, and the development of optical fiber to the roadside, to the community, to the building and to the home is rapid. , Fiber home requires operators to make reasonable plans for comprehensive construction issues such as wiring construction during home access, which puts forward many requirements in terms of networking methods, line planning, laying costs, and construction time. At present, the access network and residential and indoor power lines, video lines and network lines are all wired separately. The project is huge, the construction is cumbersome, time-consu...
