Communication Connector with Crosstalk Compensation

摘要

A communication connector comprising plug interface contacts having a plurality of conductor pairs, and corresponding cable connector contacts. A printed circuit board connects the plug interface contacts to respective cable connector contacts. The printed circuit board includes circuitry between a first conductor pair and a second conductor pair. The circuitry has a first mutually inductive coupling between a first conductor of the first conductor pair and a first conductor of the second conductor pair, a first capacitive coupling between the first conductor of the first conductor pair and the first conductor of the second conductor pair. The first capacitive coupling is approximately concurrent with the first mutually inductive coupling. A shunt capacitive coupling connects the first conductor of the second conductor pair to a second conductor of the second conductor pair.
