<p>The invention relates to a foamed twisted pair cable (23) 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 305 M (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.</p> |
