Abstract: Crosstalk is reduced in a communications wiring system by an arrangement of circuit traces on a circuit board. The circuit board has circuit traces which are arranged for interconnecting terminals in first and second electrical connectors, wherein the terminals in each connector are associated as signal pairs in the communications wiring system. The circuit board also has at least one non-ohmic trace which is not electrically connected to any of the circuit traces on the board, or to ground. The non-ohmic trace is arranged closely adjacent to at least two of the circuit traces interconnecting different signal pairs so as to couple energy therebetween, whereby crosstalk between the at least two circuit traces is reduced.
