Why are Network wires twisted?

Why are the wires inside a cat6 (or cat5e) cable twisted? The purpose is to resist radio frequency or electromotive force interference from outside the cable. Moreover, within the same cable the individual pairs are twisted at different rates (rate of pitch). This helps prevent cross-talk, or interference, from one pair set to the other. Since each pair in a 1GB network is carrying different messages (variations in voltages which represent zeros and ones), we don't want the voltage action on pair to bleed into the parallel pairs in the same cable. This twisted wire is why we also refer to network cable as UTP or STP - Un-shielded Twisted Pair and Shielded Twisted Pair. These are categorized into: Cat 1 (old fashioned "drop" or "quad" wire), Cat3 - suitable for voice, pbx or 10mbp networks Cat4 - (this category didn't last long) Cat5 - Voice or 100 Mpbs networks Cat5e - Voice or 1 gig networks Cat6 - 1 gig networks (or 10gig over short distances) Cat7 Follow us on our other channels --------------------------------------------------------------- Youtube https://youtube.com/diytelecom Youtube https://youtube.com/networkadvisor Twitter https://twitter.com/DIYTelecom Instagram https://www.instagram.com/oneconnexions Pinterest https://www.pinterest.com/nvisor Blogger: http://uplinktech.blogspot.com/ Website http://www.networkadvisor.net/ ----------------------------------------------------------------------------- CONTRIBUTIONS to support Network Advisor: https://donorbox.org/network-advisor-expansion ------------------------------------------------------------------------------
