    摘要: A cable (36) which includes eight coaxial cables (20, 22, 24, 26, 28, 30, 32, 34). The shields of pairs of 50 Ohm coaxial cables are connected together at the ends with copper tape (33, 35, 37) to form a desired 100 Ohm differential impedance. Since the impedance of the cable is set by the diameter of the 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 cable consisting of eight coax conductors properly connected together to connect to cable installations being measured. Attenuation or insertion loss of the test cables on test instruments can be compensated for by means of calibration of the instrument.
