CN203013403U - A 22-core photoelectric composite communication early warning cable used for 4G mobile communication - Google Patents

Abstract

The utility model relates to a 22-core photoelectric composite communication early warning cable used for 4G mobile communication. The 22-core photoelectric composite communication early warning cable comprises power lines, a ground wire, a filling rope, multi-core optical cables, a tearing rope, warning lines, a shielding layer, and a sheath. A cable beam is twisted by sixteen power lines, the ground wire, the filling rope, the two multi-core optical cables, and the three warning lines 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 photoelectric composite communication early warning 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 a 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.

Description

A kind of 4G tracking exchage 22 core photoelectricity composite communication early warning cables

Technical field

The utility model patent relates to a kind of 4G tracking exchage 22 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.

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 early warning 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 early warning cables, it is characterized in that: comprise power line, ground wire, gasket for packing, multi-fiber cable, tear rope, alarming line screen, sheath, the ten described power lines of the six roots of sensation, ground wire, gasket for packing, two multi-fiber cables, three stranded bunchys of alarming line, 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 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.

In a word, this cable transfers signals to tower top by multi-fiber cable, and signal attenuation is zero substantially, and the power line that simultaneously base station tower top RUU is adopted, ground wire, multi-fiber cable, alarming line comprehensively arrive stranding together, namely reduce cost, more greatly reduced 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 22 core photoelectricity composite communication early warning cables, comprise power line 1, ground wire 2, gasket for packing 3, multi-fiber cable 4, tear rope 5, alarming line 6 screens 7, sheath 8, ten six roots of sensation power lines 1, ground wire 2, gasket for packing 3, two multi-fiber cables 4, three stranded bunchys of alarming line 6, wrapped one deck screen 7 outside it, extrude one deck sheath 8 outside screen 7, vertically between screen 7 and sheath 8 put one and tear rope 5, reduce costs to reach, the purpose of constructability, monitored base stations running status.Power line 1 is 8 AWG power lines.

This cable is determined specification and the quantity of multi-fiber cable according to the mode that antenna adopts, and is determining power line, ground wire, alarming line equal-specification in conjunction with the total system scheme, then by stranded cable technological synthesis stranding.
