Abstract
The utility model relates to a 13-core photoelectric composite communication early warning cable used for 4G mobile communication. The 13-core photoelectric composite communication early warning cable comprises power lines, warning wires, a ground wire, filling ropes, a multi-core optical cable, a tearing rope, a shielding layer, and a sheath. A cable beam is twisted by eight power lines, three warning wires, the ground wire, the multiple filling ropes, and the multi-core optical cable and is wrapped in the shielding layer. The sheath is extruded round the shielding layer. The tearing rope is disposed between the shielding layer and the sheath longitudinally. The shielding layer contacts the twisted ground wire at the outer side of the cable beam in order to form a grounding wire together. The 13-core photoelectric composite communication early warning cable is characterized in that the multi-core optical cable is extended to the top of a tower by photovoltaic conversion so that a problem of attenuation caused by radio manner is substantially reduced, achieving large coverage and high transmission speed of an antenna, and that cost is substantially reduced by replacing the radio manner with a multi-core optical cable pulling away manner and replacing a copper cable with the multi-core optical cable.
Description
Technical field
The utility model relates to a kind of 4G tracking exchage 13 core photoelectricity composite communication early warning cables, and this cable comprehensively forms several cables used on the mobile base station, is widely used in mobile communication system, during particularly 4G LTE fights fiercely.
Background technology
China is in 2G, NodeB at present, generally adopted RF-wise, transmitter transfers signals to the antenna on top, base station by radio frequency cable, because there is decay in radio frequency cable, when signal reaches antenna, signal weakens, cause the coverage of base station to be dwindled, and used a large amount of copper materials in radio frequency cable, cost is very high.
Summary of the invention
In view of the deficiency that prior art exists, the utility model adopts the technology of multi-fiber cable roping, simultaneously with the scheme of the comprehensive stranding of other cable, provides a kind of 4G tracking exchage 13 core photoelectricity composite communication early warning cables.
The utility model for achieving the above object, the technical scheme of taking is: 4G tracking exchage 13 core photoelectricity composite communication early warning cables, it is characterized in that: comprise power line, alarming line, ground wire, gasket for packing, multi-fiber cable, tear rope, screen, sheath, eight described power lines, three alarming lines, ground wire, several gasket for packing, the stranded bunchy of multi-fiber cable, wrapped one deck screen outside it, extrude one deck sheath outside screen, vertically between screen and sheath put one and tear rope; Be emerging in the outer ground wire of stranding after screen and stranded bunchy and contact, jointly form earth connection, power line is 8 AWG power lines.
Characteristics of the present utility model are:
1), by opto-electronic conversion, make multi-fiber cable to tower top, greatly reduce the attenuation problem that is brought by RF-wise, make the coverage of antenna larger, transmission speed is higher.
2), change into multi-fiber cable by RF-wise and zoom out mode, change the multi-fiber cable transmission into by copper cable, reduced greatly cost.
3), the comprehensive stranding of all cables by the base station is used, greatly reduce construction cost, the conventional radio frequency of comparing mode, weight is lighter, cost is lower, it is more convenient to install.
4), can realize monitoring to the base station state by alarm cable.
This cable transfers signals to tower top by multi-fiber cable in a word, signal attenuation is zero substantially, the power line that simultaneously base station tower top RUU is adopted, ground wire, multi-fiber cable, alarming line comprehensively arrive stranding together, have namely reduced cost, more greatly reduce the cost of construction.This product is used mainly for 4G LTE base station.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1,4G tracking exchage 13 core photoelectricity composite communication early warning cables (GYTZA-1G6+8P8+1F12+3A type), comprise power line 1, alarming line 2, ground wire 3, gasket for packing 4, multi-fiber cable 5, tear rope 6, screen 7, sheath 8, eight power lines 1, three alarming lines 2, ground wire 3, several gasket for packing 4, the stranded bunchy of multi-fiber cable 7, wrapped one deck screen 7 outside it, screen 7 outer vertical put one tear rope 6 after integral extrusion one deck sheath 8 and form optoelectronic composite cable again.Be emerging in the outer ground wire 3 of stranding after screen 8 and stranded bunchy and contact, jointly form earth connection.
The mode that this cable can adopt according to antenna is determined number of fibers, then is determined power line, ground wire, alarming line equal-specification and quantity in conjunction with the total system scheme, then by the stranded cable technology with above cable twisting together.Power line 1 is 8 AWG power lines.
