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 cable, several cables used on mobile base station comprehensively form by this cable, are widely used in mobile communication system, during particularly 4G LTE fights fiercely.
Background technology
Current China is in 2G, NodeB, generally have employed RF-wise, transmitter transfers signals to the antenna on top, base station by radio frequency cable, because radio frequency cable exists decay, when signal reaches antenna, signal weakens, cause the coverage of base station to reduce, and employ 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 present invention adopts the technology of multi-fiber cable roping, simultaneously by the scheme of comprehensive for other cable stranding, provides a kind of 4G tracking exchage 13 core photoelectricity composite communication early warning cable.
The present invention for achieving the above object, the technical scheme taked is: a kind of 4G tracking exchage 13 core photoelectricity composite communication early warning cable, 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, at its outer wrapped one deck screen, outside screen, extrude one deck sheath, vertically between screen and sheath put one and tear rope; After screen and stranded bunchy, the ground wire be emerging in outside stranding contacts, and jointly form earth connection, power line is 8 AWG power lines.
Feature of the present invention is:
1), by opto-electronic conversion, make multi-fiber cable to tower top, greatly reduce the attenuation problem brought by RF-wise, make the coverage of antenna larger, transmission speed is higher.
2), by RF-wise change into multi-fiber cable and zoom out mode, change multi-fiber cable into by copper cable and transmit, greatly reduce cost.
3), by the comprehensive stranding of all cables by base station, greatly reduce construction cost, conventional radio frequency of comparing mode, weight is lighter, cost is lower, installation is more convenient.
4), the monitoring to base station state can be realized 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 simultaneously adopted by base station tower top RUU, ground wire, multi-fiber cable, alarming line are combined and are combined together stranding, namely reduce cost, more greatly reduce the cost of construction.This product is used mainly for 4G LTE base station.
Accompanying drawing explanation
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 cable (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, stranded bunchy of multi-fiber cable 7, at its outer wrapped one deck screen 7, screen 7 outer vertical put one tear rope 6 after integral extrusion one deck sheath 8 and form optoelectronic composite cable again.After screen 8 and stranded bunchy, the ground wire 3 be emerging in outside stranding contacts, and jointly forms earth connection.
The mode that this cable can adopt according to antenna, determines number of fibers, then determines power line, ground wire, alarming line equal-specification and quantity in conjunction with total system scheme, then by stranded cable technology by above cable twisting together.Power line 1 is 8 AWG power lines.
