The types of cable, 23 '12 Subject: video cable, Viewed by: 12
Different types of cables in the transmission signal quality performance difference,inaddition to some special applications, the cable used in audio and video transmissionlargely on single wires, twisted pair, coaxial and fiber-based.
1.1 for single conductor
Single conductor cable is the most basic type (such as wires), which consists ofone or agroup of wire surrounded by the plastic protective layer, this cable isgenerally used totransmit low frequency signals, such as power, audio, andcomputer ID code.
1.2. UTP
This cable consists of two or two more independent, mutually insulated cable fortwistedcomposed of a single wire diameter specifications from 20AWG to 24AWG.UTP is a relatively cheap cables, each set of wires with the same anti-jamming capability, can effectively suppress the external electromagnetic interference, andeffectively shield theelectromagnetic interference of the transmission signal to the outside world.
1.3. Coaxial cable
Is the composite of a two-conductor coaxial cable center conductor of the coaxial cablefor the transmission of signals, metal screen from the two effects: First, as a signal of public ground for the current loop signal, two suppress electromagnetic noiseinterference on the signal as the signal shielding. The coaxial cable has beenwidely used in audio and video, or radio frequency transmission, the transfer impedance is 75, has become the standard impedance of the videoTags: -->
