Abstract

The utility model relates to an 18-7AWG and 3-optical cable photoelectric composite cable for 4G mobile communication. The cable is formed by integrating several cables used in a mobile terminal and is widely applied to a mobile communication system. 18 power lines, a ground wire, a filler rope and three multi-core optical cables are twisted to form a bundle, the outside of the bundle is successively wrapped by a shield layer and is extruded with a sheath, two tearing ropes are longitudinally arranged between the shield layer and the sheath, and the power lines are 7AWG power lines. The photoelectric composite cable is characterized in that through photoelectric conversion, the multi-core optical cables can reach a tower top, so that the problem of attenuation caused by a radio frequency mode is substantially reduced, the coverage scope of an antenna is larger, and the transmission speed is higher. The radio frequency mode is converted to a multi-core optical cable remote mode, and copper cables are replaced by multi-core optical cable transmission, so that the cost is greatly reduced. By integrating all cables used in a base station to form a cable, the construction cost is substantially reduced, and compared to the conventional radio frequency mode, the weight is lighter, the cost is lower, and the installation is more convenient.

Description

18 7AWG of 4G tracking exchage and 3 optical cable photoelectric compound cables

Technical field

The utility model patent relates to the photoelectric compound cable of 18 7AWG 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 18 7AWG 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 18 7AWG 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, 18 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 7AWG 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.

Accompanying drawing explanation

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

Embodiment

As shown in Figure 1, the photoelectric compound cable of 18 7AWG of 4G tracking exchage and 3 optical cables, comprise power line, ground wire, gasket for packing, multi-fiber cable, tear rope, screen, sheath, 18 described power lines 1, 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.Reduce costs, reduce the objects such as decay, constructability to reach.Power line 1 is 7AWG 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.
