Drahtpaare
Drahtpaare, also known as twisted pairs, are a fundamental component in many telecommunication and data networking systems. They consist of two insulated electrical wires that are twisted around each other. This twisting is not merely decorative; it serves a crucial purpose in reducing electromagnetic interference, both from external sources and between the wires themselves. The twisting causes the two wires in a pair to be equidistant from external noise sources, and any interference picked up by one wire is largely canceled out by the opposite polarity interference picked up by the other. This significantly improves the signal-to-noise ratio and allows for more reliable data transmission over longer distances.
There are two main types of twisted pairs: unshielded twisted pairs (UTP) and shielded twisted pairs (STP).
