Abstract

Disclosed are an electrical connector and a method for providing transmit and receive electrical signal contacts to reduce or minimize total crosstalk. Such methods may be particularly suitable for connectors having larger near-end crosstalk aggressors than far-end crosstalk aggressors. The electrical signal contacts may be subdivided on a substrate, such as a midplane PCB, and through the opposing connectors, such that the transmitting contacts are all on one side of the connector and the receiving contacts are on the other side of the connector, with a buffer between them. The buffer may comprise a plurality of “dummy” or “buffer” contacts, which may be unassigned or devoid of electrical connectivity. This is one step beyond the primary assignment of contacts as single-ended or differential signal contacts. The contacts themselves may also receive a secondary assignment according to their desired transmitting, receiving, or buffering function.
