Abstract:
The invention provides a means of reducing crosstalk in data connectors and includes a first conductive signal path and a second conductive signal path. The first signal path includes crossover connection means for changing over the position of the first signal path at a point intermediate between the ends of the first and second paths to reduce crosstalk in the first and second paths through the introduction of antiphase signals. In practice this antiphase crosstalk can be applied by a network of PCB tracks (36) to simulate the conductors.
