The twisted pair comprises at least two insulated conductors twisted around each other and protected by an insulating cover. A cable of this type usually contains 1, 2 or 4 pairs, ie 2, 4 or 8 threads.
Stranded wires or two-wire cabling system are used worldwide for telephony. It is a well known technology. The cable is fairly inexpensive and easy to install and reliable connections. Its major advantages are therefore their availability and low cost.
As for the disadvantages are the large signal attenuation with increasing distance and are very susceptible to electrical interference. Therefore instead of using parallel wire cable twisted and is used to avoid interference, the set of pairs is shielded with a conductive mesh does. This raises the cost of the cable itself, but its installation and continuous connection still cheaper than in the case of coaxial cables. Both the EtherNet networks like Token Ring can use this type of cable.
