Abstract

A low crosstalk connector configuration includes a terminal face, and at least three pairs of elongated parallel electrical connector terminals, wherein each pair is aligned in a plane normal to the terminal face. A first pair of terminals is aligned in a plane parallel to a second plane in which a second pair of terminals is aligned. A first distance between midpoints of the first and the second pairs of terminals in a direction parallel to the first and the second planes, equals a second distance between the midpoints in a direction perpendicular to the first and the second planes. A third pair of terminals is aligned in a third plane perpendicular to the first and the second planes. The third plane coincides with a point between either of the first or the second pair of terminals. A cable and connector assembly includes a length of cable with at least three pairs of twisted wires, with each wire pair connected to a corresponding pair of the connector terminals.
