During termination of twisted pair cabling, what should be done to ensure minimal cross talk is introduced? ​No more than 1 inch of the cable should be exposed. ​ No less than 1 inch of the cable should be exposed. ​Each pair should be stripped of insulation so that it doesn't get caught in the jack. ​ Each pair should be twisted around another pair to reduce cross talk.
