Modeling Copper Cables and Connectors

Abstract

High-speed data busses constructed from copper components are both difficult to model and important to accurately simulate. Using analytic signal theory and an extension of the skin effect for non-uniform conductivity, experimental data taken from IEEE 1394-1995 cables and connectors is used to predict the transfer function of a 4.5 meter cable with two connectors. With these techniques any length of cable between two connectors can be simulated with high accuracy, including all the cable and connector losses and the infinitely summed standing waves that occur between the connectors.
