Abstract

The utility model relates to a composite cable for three-net integration, which comprises a cable core wrapping tape as well as an optical unit, a plurality of data line pairs and a coaxial video cable arranged in the cable core wrapping tape, wherein the cable core wrapping tape is coated with a shielding layer; and an outer protective layer is extruded outside the shielding layer. The composite cable has the advantages that the composite cable for three-net integration has good shielding effect so that the interference of electromagnetic waves can be prevented effectively; the transmission distance by optical fiber is long, and the attenuation of high frequency is small so that smart and remote control can be achieved; and video transmission and digital signal transmission are integrated so as to avoid repeated wiring and save construction cost. In addition, the data line pairs can also be used as power transmission lines.

Description

Composite rope is used in a kind of integration of three networks

Technical field

The present invention relates to a kind of composite rope, composite rope is used in particularly a kind of integration of three networks.

Background technology

The broadcasting and TV system just united the notion that proposes NGB (broadcasting and television network of future generation) with the Department of Science and Technology as far back as 2008, had formally put into effect concrete pilot at present and had implemented construction scheme.See from the NGB network architecture; Its essential characteristic is consistent with telecommunication network development tendency; Removing the last 100m of Access Network possibly combine the broadcasting and TV characteristic to adopt EoC (EthernetoverCoax; Ethernet transmits at coaxial cable) outside the technology, at aspects such as the main network architecture of the backbone network of basic network part, metropolitan area network, Access Network, networking model, the choices of technology, the two is all basic identical.

The NGB Access Network has the obvious characteristic that is different from the telecommunications broadband access network, possesses the representative elements of carrying following operation demand.Plan last 100 meters of NGB Access Network with FTTB+LAN and FTTB+EOC.

Summary of the invention

Technical problem to be solved by this invention is to provide the integration of three networks that a kind of shield effectiveness is good, long-range is controlled to use composite rope.

For achieving the above object, the present invention solves the scheme that its technical problem takes and is:

Composite rope is used in this integration of three networks, comprise the cable core band be arranged on the light unit in the cable core band, a plurality of data wire to coaxial vision cable, said cable core band periphery is coated with screen, said screen has extruded outer jacket outward.

Preferably, be provided with a pair of optical fiber, two gasket for packings and reinforcement in the said smooth unit, said optical fiber outer periphery is equipped with optical fiber loose tube, and said smooth unit is coated with water blocking layer, and said water blocking layer also is provided with sheath outward.

Preferably, said data wire is to being made up of cable core cable core band outer with being coated on cable core and the screen that extrudes the cable core band outside, and the said cable heart is by conductor and be coated on conductor insulating barrier outward and form.

Preferably, said coaxial vision cable center is provided with conductor, and said conductor is outside equipped with insulating barrier, and said insulating barrier is coated with the said band of band and has extruded outer conductor outward, and said outer conductor is outside equipped with oversheath.

Preferably, said insulating barrier is polyethylene layer.

Preferably, said screen is the copper wire woven shield.

The present invention compared with prior art has advantage: this integration of three networks is good with the composite rope shield effectiveness, can effectively prevent Electromagnetic Interference; The Optical Fiber Transmission distance, high-frequency transmission decay is little, can realize intellectuality, long-range control, and collection video transmission, digital data transmission be one, avoids repeating wiring, saves construction cost, and data are used also can be used as power transmission line simultaneously.
