Abstract: A communication connector assembly that incorporates crosstalk compensation. A number of compensation coupling contacts, e.g., conductive pads, stiff wires or plates, are mounted on a front edge region of a wire board that supports a number of terminal contact wires. Compensation elements associated with the wire board are connected to the contacts and are selected to produce, e.g., capacitive crosstalk compensation coupling.
