Description
Technical field
The present invention relates to a kind of communication cable, in particular for a kind of novel combination cable of transmitting radio frequency signal, gps signal and electric power signal simultaneously of TD-SCDMA standard base station system.
Background technology
In the base station system of TD-SCDMA standard, needing to use smart antenna to carry out signal covers, the main feeder usage quantity of the smart antenna of each sector is 9, and it is 27 that three sectors amount to use main feeder quantity, compares traditional GSM base station and uses the quantity of feeder line to increase greatly.Cause the base station construction cost to increase, make the engineering construction difficulty strengthen simultaneously.
Simultaneously, because the frequency height of the frequency ratio GSM standard of TD-SCDMA standard causes TD-SCDMA standard signal of base station area coverage to reduce, in same scope, want the requirement for signal coverage that reaches same, TD-SCDMA standard base station construction quantity will significantly increase.
Because the base station produces radiation, people's healthy meeting is affected, so, often, select the site, base station to become the difficult problem of operator because radiation impacts near resident productive life in the place that has the base station.
At present, in the base station system of TD-SCDMA standard, the feeder line transmission manner is still adopted in the signal transmission, needs 27 main feeders, 1 GPS feeder line, and the base station floor space is big, the base station density height, the engineering construction difficulty is big, base station cost height.
Owing to be subjected to the restriction of coaxial cable transmission technology and the influence of GSM base station construction technology, the signal transmission adopts the above-mentioned shortcoming of traditional physical foam insulation coaxial cable effectively to be solved so far, becomes a big technical barrier of restriction industry development.
Therefore, need badly a kind of integrated level height, main feeder quantity is few, radiation is little, loss is little, in light weight, cost is low and novel cable flexibly easy to use.
Summary of the invention
The objective of the invention is to overcome above-mentioned existing deficiency, a kind of novel combination cable of a kind of transmitting radio frequency signal simultaneously, gps signal and electric power signal be provided, this product loss is little, in light weight, cost is low and also easy to use flexibly.
Technical scheme of the present invention is:
Through stranding, wrapped then, the outside polyolefin outer protective sleeve that wraps up extrusion molding again makes by two core optical cables, power cable in the present invention.
The present invention is can also be by six roots of sensation optical cable, 2 power cables and a braid through stranding, and wrapped then, the outside figure of eight polyolefin outer protective sleeve that wraps up extrusion molding again makes.
Optical cable is used for transmitting optical signal, power cable is used for to the photoelectric conversion device power supply that is positioned at the launching tower top, braid is used for to the gps antenna transmission signals, and braid and optical cable, power cable are integrated in the cable, makes things convenient for the installation and the construction of gps antenna.
A kind of novel combination cable, be used for the communication signal of TD-SCDMA base station is transferred to the emission cat head, it includes optical cable, power cable, described optical cable, power cable are wrapped in the outer protective sleeve, be provided with filler in the outer protective sleeve, power cable connects the power port of the photoelectric conversion device be positioned at the emission cat head, optical cable connect photoelectric conversion device signal input part.
It also comprises braid, described optical cable, power cable and braid are wrapped in the outer protective sleeve that the cross section is the figure of eight, optical cable and power cable are wrapped in first sheath unit of outer protective sleeve, braid is wrapped in second sheath unit of outer protective sleeve, first sheath unit and second sheath unit are the pipe shape, first sheath unit and second sheath unit are an integral body, and forming the cross section is the outer protective sleeve of the figure of eight.
Described optical cable from-inner-to-outer is made up of optical fiber, aramid fiber layer and pvc sheath successively.
Be provided with one deck modified poly ethylene between described optical fiber and the aramid fiber layer.
Described power cable from-inner-to-outer is made up of power cable inner wire and power cable insulation layer successively.
Described braid from-inner-to-outer is made up of braid inner wire, braid insulating barrier and braid successively.
Be provided with filler in first sheath unit of described outer protective sleeve.
Described filler is wrapped nonwoven fabrics.
Be provided with six roots of sensation optical cable and two power cables in first sheath unit of described outer protective sleeve, the both sides of two power cables respectively are provided with three optical cables.
The invention has the beneficial effects as follows:
Through stranding, wrapped then, cohering alkene oversheath again, and then make finished product twists together optical cable and flexible cable, extrudes the splayed sheath with braid then and forms by optical cable, flexible cable and a braid in the present invention; Six roots of sensation optical cable replaces 27 traditional main feeders as main feeder.The optical cable loss is little, makes the distance between antenna and the machine room can be farther, and product weight is light, and cost is low, and easy to use flexibly; After as long as the position of machine room is chosen, antenna can select more suitable position to install according to actual conditions, braid is climbed up the emission iron tower together in company with main feeder simultaneously, it is also convenient flexible that gps antenna is installed, and after the combination cable that adopts comprehensive boundling form carries out signal transmission, help carrying out the distributed base station construction, well solved the problem of machine room addressing difficulty.
In traditional base station construction, the equipment of opto-electronic conversion is in machine room, and after adopting optical cable to carry out the signal transmission, the equipment of opto-electronic conversion will be placed on the top of iron tower, just near the place of antenna, has increased conversion efficiency, has reduced signal attenuation.Only need add that a power line needs the problem of power supply with regard to having solved photoelectric conversion device, safe and reliable.
The present invention adopts the optical cable transmitting radio frequency signal, and transmission attenuation is little, and transmission range is farther, can carry out the distributed base station construction, builds other base station around a core machine room, solves the problem of addressing difficulty.
The present invention combines braid and optical cable and power cable, makes braid climb up iron tower with main feeder, makes things convenient for the installation of gps antenna, can make construction convenient like this.
The present invention extrudes one deck modified poly ethylene outside plastic fiber, have good especially flexibility, can well protect optical fiber, and be easy to peel off, and is convenient to construction.The attached aramid yarn of tightly packaged fiber outsourcing strengthens the product tensile property, is convenient to construction.
The present invention not only can transmitting radio frequency signal, all right transmit GPS signal, and electric power signal, not only overcome the big difficulty of the many difficulty of construction of traditional base station feeder line, and can adopt the construction mode of distributed base station, and make that to build base station methods more flexible, solved the problem that site, base station difficulty is selected by operator effectively, solved the bottle footpath problem that runs in the TD-SCDMA standard process of construction, for the fast development of this standard and as early as possible networking effectively solution is provided.And this product weight is light, easy construction, and cost is low, and construction speed is fast, is the first-selected product of operator, can be good at satisfying application request, has higher flexibility and adaptability, simplifies debugging difficulty simultaneously.
