Three types of cables (commercially available high-performance coaxial and ribbon cables, and an experimental flexible-film cable) were investigated for intrasystem communication in high-performance computer and communication systems. The electrical properties of the cables and their respective connectors were obtained and compared through the use of time-domain techniques. Feasibility for use in digital signal propagation at 500 Mb/s-1 Gb/s was demonstrated by means of pulse propagation and eye-diagram measurements. Performance limits in terms of maximum useful cable lengths were determined through simulations which included the effects of associated connectors, vias, and printed-circuit-card wiring.
