The continuous improvement of development and computer performance, requirement of the people to comprehensive wiring system performance is also higher and higher, and network passes at present
Defeated rate is increased to 100Mb from pervious 10Mb and gigabit LAN technology, network rate increasingly improve, it is meant that work
The raising of working frequency, working frequency is higher, and signal transmission attenuation is bigger.
Communication cable refers to the high frequency carrier for low coverage voice communication and long distance and the electricity of digital communication and signal transmission
Cable is one of big cable product in China five；According to the purposes and use scope of communication cable, six big series of products can be divided into and (claimed
For six class electricity comprehensive digital communication cables), i.e., city communication cable (including paper insulation city talk about cable, polyolefin insulation polyolefin jacket city
Interior words cable), (including paper insulation low-and high-frequency long distance symmetric cable, copper core foamed polyethylene low-and high-frequency are long-distance right for long distance symmetric cable
Claim cable and Digital Transmission long distance symmetric cable), coaxial cable (including small diameter coaxial cable, in coaxial and small coaxial electrical
Cable), submarine cable (can divide symmetrical seabed and coaxial submarine cable), fiber optic cables are (including traditional cable-type, band-like array type
With three kinds of matrix type), radio-frequency cable (including symmetric radio frequency and coaxial radio-frequency).
Six traditional class electricity comprehensive digital communication cables use solid core polyethylene insulation technical pattern, and cable core is transmitted in high frequency to decline
Subtract greatly, and enterprise market competition is very fierce, with being continuously increased for the cost of raw material, so that with solid core polyethylene insulation skill
Six class electricity comprehensive digital communication cable costs of art are higher and higher.
In modern intelligentized audio-video transmission system, security protection video transmission is often one of subsystem, and
With very important status.In traditional design and construction, often network layout and security protection video monitoring wiring are separated
Consider, do so be often as using transmission medium difference, unify people they can not well to together；But
As security protection video Image Acquisition point and other sensors etc. are deployed to ensure effective monitoring and control of illegal activities being continuously increased a little in building, the cables such as coaxial cable
Number of wires, which increases, can occupy a large amount of pipeline resource, and wiring is difficult, can also cause image matter when being routed longer
The decline of amount.With the increase of transmission range, the solution based on conventional coaxial cable is taken cannot in many aspects
Meets the needs of construction and application, it is therefore desirable to which one kind new wire and cable and its associated solutions replace, to solve
Certainly modern digital video monitoring system requires signal cable long transmission distance and the small requirement of signal transmission attenuation.
