Abstract
Abstract A method is disclosed for improving the transmission properties of balanced and unbalanced connectorized flat cable interconnection assemblies. In accordance with the method, a first set of generally parallel flat cable conductors are terminated on a first mapped set of connector contacts such that all conductors are connectable to a source of ground potential. A second set of generally parallel flat cable conductors are terminated on a second mapped set of connector contacts such that the odd-numbered conductors are connectable to a source of ground potential and the even-numbered conductors are connectable to a plurality of signal sources. The termination of flat cable conductors in accordance with this method also results in an improvement in the packaging density of pluggably interconnectable circuits.
