Abstract
The invention relates to a 13-core photoelectric composite communication early-warning cable for 4G mobile communication, which comprises power lines, alarm lines, an earth wire, fillers, a multicore cable, a rip cord, a shielding layer and a sheath, wherein eight power lines, three alarm lines, one earth wire, a plurality of fillers and one multicore cable are twisted into a bundle, the bundle is wrapped with a shielding layer, a sheath is extruded outside of the shielding layer, and the rip cord is longitudinally placed between the shielding layer and the sheath; and the shielding layer is contacted with the earth wire which is exposed to the outside of the twisted bundle so as to jointly form a ground lead. The early-warning cable disclosed by the invention has the characteristics that through photoelectric conversion, the multicore cable extends to the top of a tower, thereby significantly reducing an attenuation problem caused by using a radio frequency mode, in such a way, the coverage range of an antenna is larger, and the transmission speed is higher. The radio frequency mode is changed into a remote multicore cable mode, and a copper cable transmission mode is changed into a multicore cable transmission mode, so that the cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of 4G tracking exchage 13 core photoelectricity composite communication early warning cables, 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, signal weakened when signal reached antenna, cause the coverage of base station to be dwindled, and used a large amount of copper materials in the radio frequency cable, cost is very high.
Summary of the invention
In view of the deficiency that prior art exists, the present invention 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 present invention for achieving the above object, the technical scheme of taking is: a kind of 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, outside screen, extrude one deck sheath, vertically between screen and sheath put one and tear rope; Be emerging in the outer ground wire of stranding behind screen and the stranded bunchy and contact, jointly form earth connection, power line is 8 AWG power lines.
Characteristics of the present invention are:
1), by opto-electronic conversion, make multi-fiber cable to cat head, 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 cat head by multi-fiber cable in a word, signal attenuation is zero substantially, the power line that simultaneously base station cat head RUU is adopted, ground wire, multi-fiber cable, alarming line comprehensively arrive together stranding, 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 invention.
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, multi-fiber cable 7 stranded bunchys, 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 behind screen 8 and the stranded bunchy and contact, jointly form earth connection.
The mode that this cable can adopt according to antenna is determined number of fibers, determines power line, ground wire, alarming line equal-specification and quantity in conjunction with the total system scheme again, then by the stranded cable technology with above cable twisting together.Power line 1 is 8 AWG power lines.
