Abstract
The utility model relates to a 22-core photoelectric composite communication cable used for 4G mobile communication. The 22-core photoelectric composite communication cable comprises power lines, a ground wire, a filling rope, multi-core optical cables, a tearing rope, a shielding layer, and a sheath. A cable beam is twisted by eighteen power lines, the ground wire, the filling rope, and three multi-core optical cables 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 power lines are 8AWG power lines. The 22-core photoelectric composite communication cable is characterized in that the multi-core optical cables are 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 cables. Construction cost is substantially reduced by synthetically preparing all cables used by a base station. Compared with a conventional cable using a radio manner, the 22-core photoelectric composite communication cable has characteristics of lighter weight, lower cost, and easier installation.
Description
Technical field
The utility model patent relates to a kind of 4G tracking exchage 22 core photoelectricity composite communication cables, and this cable comprehensively forms several cables used on the mobile base station, is widely used in mobile communication system.
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 reached antenna, signal weakened, and caused 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 22 core photoelectricity composite communication cables.
The utility model for achieving the above object.The technical scheme of taking is: a kind of 4G tracking exchage 22 core photoelectricity composite communication cables, it is characterized in that: comprise power line, ground wire, gasket for packing, multi-fiber cable, tear rope, screen, sheath, 18 described power lines, ground wire, gasket for packing, three stranded bunchys 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; Described power line is the 8AWG power line.
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, and weight is lighter, cost is lower, it is more convenient to install.
In a word, this cable transfers signals to tower top by multi-fiber cable, and signal attenuation is zero substantially, and the power and ground that simultaneously base station tower top RUU is adopted is stranding together with multi-fiber cable comprehensively arrives, and provides optical signal transmission and supply of electric power for RRU simultaneously.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 22 core photoelectricity composite communication cable (GYTZA-1G6+18P8+3F12
Type), comprise power line 1, ground wire 2, gasket for packing 3, multi-fiber cable 4, tear rope 5, screen 6, sheath 7,18 power lines 1, ground wire 2, gasket for packing 3, three stranded bunchys of multi-fiber cable 4, wrapped one deck screen 6 outside it, extrude one deck sheath 7 outside screen 6, vertically between screen 6 and sheath 7 put one and tear rope 5, reduce costs, reduce the purposes such as decay, constructability to reach.Power line 1 is the 8AWG power line.
This cable is determined the quantity of multi-fiber cable according to the mode that antenna adopts, then determines power line, ground wire equal-specification in conjunction with the total system scheme, then by stranded cable technological synthesis stranding.
