CN203013381U - An 8-core high-capacity photoelectric composite cable used for 4G mobile communication - Google Patents

Abstract

The utility model relates to an 8-core high-capacity photoelectric composite cable used for 4G mobile communication. The 8-core high-capacity photoelectric composite cable comprises power lines, a ground wire, filling ropes, an optical fiber, a tearing rope, a shielding layer, and a sheath. A cable beam is twisted by six power lines, the ground wire, multiple filling ropes, and the optical fiber 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 10AWG power lines. The 8-core high-capacity photoelectric composite cable is characterized in that the optical fiber is extended to the top of a tower by photovoltaic conversion so that a problem of attenuation caused by 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 optical fiber pulling away manner and replacing a copper cable with the optical fiber. Construction cost is substantially reduced by synthetically preparing all cables used by a base station. Compared with a conventional cable using a radio manner, the 8-core high-capacity photoelectric composite cable has characteristics of lighter weight, lower cost, and easier installation.

Description

The 4G tracking exchage 8 large capacity photoelectric compound cables of core

Technical field

The utility model patent relates to a kind of 4G tracking exchage 8 large capacity photoelectric compound cables of core, and this cable comprehensively forms several cables used on the mobile base station, is widely used in mobile communication system, particularly in the 4GLTE base station.

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 existing radio frequency coaxial-cable exists, the utility model adopts the technology of fiber optic stretch, simultaneously with the scheme of the comprehensive stranding of other cable, provides a kind of 4G tracking exchage 8 large capacity photoelectric compound cables of core.

The utility model for achieving the above object.The technical scheme of taking is: a kind of 4G tracking exchage 8 large capacity photoelectric compound cables of core, it is characterized in that: comprise power line, ground wire, gasket for packing, optical fiber, tear rope, screen, sheath, the described power line of the six roots of sensation, ground wire, several gasket for packing, the stranded bunchy of optical fiber, wrapped one deck screen outside it, extrude one deck sheath outside screen, vertically between screen and sheath put one and tear rope; Power line 1 is the 10AWG power line.

Characteristics of the present utility model are:

1), by opto-electronic conversion, make optical fiber 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 the fiber optic stretch mode by RF-wise, change Optical Fiber 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.

This cable transfers signals to tower top by optical fiber in a word, and signal attenuation is zero substantially, and the power and ground that simultaneously base station tower top RUU is adopted is stranding together with optical fiber comprehensively arrives, and provides optical signal transmission and supply of electric power for RRU simultaneously.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 Fig. 1, the 4G tracking exchage 8 large capacity photoelectric compound cables of core (GYTZA-1G6+6P10+1F12 type), comprise power line 1, ground wire 2, gasket for packing 3, optical fiber 4, tear rope 5, screen 6, sheath 7, six roots of sensation power line 1, ground wire 2, several gasket for packing 3, the stranded bunchy of optical fiber 4, wrapped one deck screen 6 outside it, extrude one deck sheath 7 outside screen 6, vertically between screen 6 and sheath 7 put one and tear rope 5, reduce costs, reduce the purposes such as decay, constructability to reach.Power line 1 is the 10AWG power line.

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