Abstract

An enhanced communication connector assembly capable of meeting Category 6 performance levels with respect to near end crosstalk (NEXT), when the assembly is connected to a mating connector. The assembly includes a wire board, and a number of elongated terminal contact wires with base portions that are supported on the board. The contact wires have free end portions opposite the base portions for making electrical contact with a mating connector. A crosstalk compensating device on the wire board is constructed and arranged to cooperate with sections of selected terminal contact wires to provide capacitive compensation coupling between the selected terminal contact wires, when the contact wires are engaged by the mating connector.

Claims
