Abstract
A method of constructing twisted pair cables having an average impedance of no less than 97.5.OMEGA. and no more than 102.5.OMEGA. is disclosed. The longest lay length pair is used as a base reference and the construction of each additional twisted pair is altered to better match the averaged impedance. Specifically, the insulated conductor thickness T.sub.i of each twisted pair is adjusted, dependent upon the configuration of the base pair.
