ABSTRACT:
Connectors, such as 110-type patch plugs, are designed to reduce near-end crosstalk that is generated when the connector is mated to a corresponding receptacle, such as a 110-type connecting block. Connectors of the present invention employ a two-stage crosstalk compensation scheme in which a first stage induces a compensating crosstalk signal, having opposite polarity as the original crosstalk signal, while the second stage induces a counter-balancing crosstalk signal, having same polarity as the original crosstalk signal. The two-stage, counter-balanced crosstalk compensation scheme of the present invention takes into account both the magnitude of the original crosstalk signal as well as the phase differences between the original crosstalk signal and the compensating and counter-balancing crosstalk signals that result from the different locations along the signal path at which the crosstalk signals are induced. The contacts of the connector are designed such that the magnitudes and locations of the compensating and counter-balancing crosstalk signals provide effective crosstalk compensation over a particular range of frequencies, e.g., 1 MHz to 200 MHz.
