Twisting wires decreases interference because the loop area between the wires (which determines the magnetic coupling into the signal) is reduced. In balanced pair operation, the two wires typically carry equal and opposite signals (differential mode) which are combined by subtraction at the destination. The noise from the two wires cancel each other in this subtraction because the two wires have been exposed to similar EMI.<br \/>\nThe twist rate (usually defined in twists per metre) makes up part of the specification for a given type of cable. The greater the number of twists, the greater the attenuation of crosstalk. Where pairs are not twisted, as in most residential interior telephone wiring, one member of the pair may be closer to the source than the other, and thus exposed to slightly different induced EMF.<br \/>\nReference: KRUTZ, Ronald L. &#038; VINES, Russel D., The CISSP Prep Guide: Mastering the Ten Domains of Computer Security, 2001, John Wiley &#038; Sons, Page 101. and <a href=\"http:\/\/www.consultants-online.co.za\/pub\/itap_101\/html\/ch04s05.html\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">http:\/\/www.consultants-online.co.za\/pub\/itap_101\/html\/ch04s05.html<\/a><\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>In the UTP category rating, the tighter the wind: A. the higher the rating and its resistance against interference and crosstalk.
