A cable which includes eight coaxial cables. The shields of pairs of 50 Ohm coaxial cables are connected together at the ends with copper tape to form a desired, 100 Ohm differential impedance. Since the impedance of the cable is set by the diameter of an inner conductors and the corresponding dielectric the , impedance is, independent of proximity of adjacent pairs or the proximity of hands or other, conductive surfaces. As such the stability of such a cable is improved over a typical, four pair cable. Additionally the conductors can always be oriented the same way, within the plug. Test instruments can make stable measurements including "return, loss" measurements when using test …

Why it's free to use
- Filed June 14, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 14, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 14, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
