2.1. Twisted Pair Cable
2.1.1. Specifications of Twisted Pair Cable
Twisted pair cables consist of copper wires of small diameters which are usually less than 0.1 inch for telephone, in-house, and office applications. Within a plastic covering shield, there are many individually insulated copper wires twisted with each other in pairs. Two wires in a tightly twisted pair experience almost the same physical environment. Therefore, radio emission and noise pickup are minimized when a differential signal is carried over the twisted pair. Furthermore, each twisted pair has its own twisting angle to minimize crosstalk between different pairs. The quality of the insulation material, the tightness and the precision of twists, and the diameter of the ...
