Abstract
Abstract A communication connector having a plurality of contact pairs for conductive connection to respective communication signal wire pairs is provided with a capacitor label that capacitively couples a first contact of one contact pair to a second contact of a second contact pair to reduce near end cross talk between adjacent contacts. A common conductive lamina disposed closely adjacent to and spaced from more than one of the contacts further improves near end cross talk performance of the communication connector.
