Abstract
We provide a twisted pair cable which is exceptionally suitable for high frequency signal transmission. One embodiment provides a twisted pair cable having a center-to-center conductor spacing at any point along a 1000 ft. cable that varies .+-.0.03 times the average of the center-to-center conductor. Another embodiment provides a twisted pair cable having an impedance of 90 to 110 ohms with a tolerance of .+-.5% of an average impedance. The preferred twisted pair cable has their dielectrics joined along the entire length thereof. Preferably, the two adjoined insulated conductors have an adhesion strength of between 0.1 to 5 lbs. force and preferably 0.25 to 2.5 lbs. force.
