Abstract
The utility model relates to a 1/2 single mode photoelectric composite cable for 4G mobile communication. The 1/2 single mode photoelectric composite cable is formed by integrating power lines and optical cables used in a mobile base station, and is widely applied to mobile communication system. A cable beam is twisted by two power lines, a plurality of filling ropes and two pairs of single mode optical fibers, the cable beam is sequentially wrapped with a layer of wrapping belt, longitudinally wrapped and welded with a corrugated aluminum outer conductor and extruded with a layer of sheath, and a rip cord is longitudinally arranged between the wrapping belt and the corrugated aluminum outer conductor. The 1/2 single mode photoelectric composite cable is characterized by greatly reducing the attenuation problem caused by adopting a radio frequency mode, and achieving larger coverage area and higher transmission speed of an antenna. The radio frequency mode is changed into a remote optical fiber pulling away mode, and a copper cable transmission mode is changed into an optical fiber transmission mode, so that the cost is greatly reduced. Through synthetically cabling all cables used by a base station while the size of the outer conductor is 1/2 shape and size of the traditional RF cables, the installation is more convenient and firm, and the construction cost is reduced. Compared with the conventional cable adopting the radio frequency manner, the 1/2 single mode photoelectric composite cable has advantages of lighter weight, lower cost, and easier installation.
Description
Technical field
The utility model patent relates to a kind of 4G tracking exchage 1/2 single mode photoelectric compound cable, and this cable comprehensively forms power line used on mobile base station and optical cable, 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 existing radio frequency coaxial-cable exists, the utility model adopts the technology of fiber optic stretch, simultaneously by the scheme of the comprehensive stranding of other cable, provides a kind of 4G tracking exchage 1/2 single mode photoelectric compound cable.
The utility model for achieving the above object.The technical scheme of taking is: a kind of 4G tracking exchage 1/2 single mode photoelectric compound cable, it is characterized in that: comprise power line, gasket for packing, single mode fiber cable, band, tear rope, embossing aluminium outer conductor, sheath, two described power lines, several gasket for packing, two pairs of stranded bunchys of monomode fiber, outside it successively wrapped one deck band, vertical bag welding embossing aluminium outer conductor, extrude one deck sheath, vertically between band and embossing outer conductor put one and tear rope.
Feature of the present utility model is:
1), by opto-electronic conversion, make optical fiber 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 fiber optic stretch mode by RF-wise, change Optical Fiber Transmission into by copper cable, reduced greatly cost.
3), by the comprehensive stranding of all cables that base station is used, outer conductor size adopts traditional radio frequency cable 1/2 form and size, make to install more convenient firmly, greatly reduce construction cost, the conventional radio frequency of comparing mode, weight is lighter, cost is lower, it is more convenient to install.
This cable transfers signals to tower top by optical fiber in a word, and signal attenuation is zero substantially, and the power and ground simultaneously base station tower top RUU being adopted and optical fiber are combined and is 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 1,4G tracking exchage 1/2 single mode photoelectric compound cable, comprise power line 1, gasket for packing 2, single mode fiber cable 3, band 4, tear rope 5, embossing aluminium outer conductor 6, sheath 7, two power lines 1, several gasket for packing 2, two pairs of stranded bunchys of monomode fiber 3, wrapped one deck band 4 outside it, in the outer vertical bag one deck embossing aluminium outer conductor 6 of layer band 4 at interface solder up embossing, finally outside embossing aluminium outer conductor 6, extrude one deck sheath 7, vertically between band 4 and embossing outer conductor 6 put one and tear rope 5.Reduce costs, reduce the objects such as decay, constructability to reach.
The outer conductor external diameter of 4G tracking exchage 1/2 single mode photoelectric compound cable is 1/2 inch.
