Abstract

The utility model relates to a 4G mobile communication photoelectric composite cable with 9 5AWGs and 3 optical cables. The cable is formed by integrating several cables used by a mobile base station, and is widely used in a mobile communication system. 9 power supply wires, a ground wire, a filling rope and 3 multi-core optical cables are twisted into a bundle, and are wrapped by a shielding layer. A sheath layer is extruded. Two tear ropes are longitudinally placed between the shielding layer and the sheath. The power supply wires are 5AWG power supply wires. The cable is characterized in that through photoelectric conversion, the multi-core optical cables reach the top of a tower; the problem of attenuation, which is caused by a radio frequency mode, is greatly reduced; the coverage of an antenna is large, and the transmission speed is fast; the radio frequency mode is converted into the mode of pulling away the multi-core optical cables; a copper cable is changed into the multi-core optical cables for transmission; the cost is greatly reduced; all cables used by the base station are integrated into the cable, which greatly reduces the construction cost; and compared with the traditional radio frequency mode, the cable has the advantages of lighter weight, lower cost and easier installation.

Description

The photoelectric compound cable of 9 5AWG of 4G tracking exchage and 3 optical cables

Technical field

The utility model patent relates to the photoelectric compound cable of 9 5AWG of a kind of 4G tracking exchage and 3 optical cables, and this cable comprehensively forms several cables used on mobile base station, is widely used in mobile communication system.

Background technology

China is in 2G, NodeB at present, generally adopt 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, and causes the coverage of base station to be dwindled, and in radio frequency cable, used a large amount of copper materials, 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 by the scheme of the comprehensive stranding of other cable, provides the photoelectric compound cable of 9 5AWG of a kind of 4G tracking exchage and 3 optical cables.

The utility model for achieving the above object.The technical scheme of taking is: the photoelectric compound cable of 9 5AWG of a kind of 4G tracking exchage and 3 optical cables, it is characterized in that: comprise power line, ground wire, gasket for packing, multi-fiber cable, tear rope, screen, sheath, nine described power lines, a ground wire, a gasket for packing, three stranded bunchys of multi-fiber cable, outside it successively wrapped one deck screen, extrude one deck sheath, vertically between screen and sheath put two and tear rope; Described power line is 5AWG power line.

Feature of the present utility model is:

1), by opto-electronic conversion, make multi-fiber cable to tower top, greatly reduce the attenuation problem being 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 multi-fiber cable transmission into by copper cable, reduced greatly cost.

3), by the comprehensive stranding of all cables that 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.

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 base station tower top RUU is adopted and multi-fiber cable are combined and be combined together stranding, simultaneously for RRU provides optical signal transmission and supply of electric power.This product is used mainly for 4G LTE base station.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, the photoelectric compound cable of 9 5AWG of 4G tracking exchage and 3 optical cables, comprise power line 1, ground wire 2, gasket for packing 3, multi-fiber cable 4, tear rope 5, screen 6, sheath 7, nine power lines 1, ground wire 2, gasket for packing 3, three stranded bunchys of multi-fiber cable 4, outside it successively wrapped one deck screen 6, extrude one deck sheath 7, vertically between screen 6 and sheath 7 put two and tear rope 5.Reduce costs, reduce the objects such as decay, constructability to reach.Power line 1 is 5AWG power line.

The mode that this cable can adopt according to antenna, determines the quantity of multi-fiber cable, then determines power line, ground wire equal-specification in conjunction with total system scheme, then by stranded cable technological synthesis stranding.
