A METHOD OF DESIGNING A DATA TRANSMISSION CABLE AND A DATA TRANSMISSION CABLE

摘要

A method of constructing twisted pair cables having an average impedance of no less than 97.5 Ω and no more than 102.5 Ω is disclosed. The longest lay length pair (42) is used as a base reference and the construction of each additional twisted pair (44, 46, 48) is altered to better match the averaged impedance. Specifically, the insulated conductor thickness Tsubi/sub of each twisted pair is adjusted, dependent upon the configuration of the base pair.
