Abstract

Electrical connector including a plurality of mating conductors. Each of the mating conductors extends between an engagement portion and an interior portion. The engagement portions of the mating conductors are configured to engage contacts of the mating connector. The engagement portions are located proximate to one another at a first nodal region. The interior portions are located proximate to one another at a second nodal region. The electrical connector also includes a first open-ended conductor electrically connected to the engagement portion of a first mating conductor of the plurality of mating conductors and extending from the first nodal region. The electrical connector also includes a second open-ended conductor electrically connected to the interior portion of a second mating conductor of the plurality of mating conductors and extending from the second nodal region. The first open-ended conductor is capacitively coupled to the second open-ended conductor.

Claims

1. An electrical connector comprising:

a connector body configured to receive a mating connector;

a plurality of first terminals and respective second terminals configured to transmit signal current therebetween, the first terminals being located proximate to one another at a first nodal region, the second terminals being located proximate to one another at a second nodal region;

a first compensation region formed by the first terminals at the first nodal region;

a second compensation region formed by the second terminals at the second nodal region;

and where in the first compensation is electrically in parallel with the second compensation region.

2. The electrical connector of claim 1, further comprising:

a first open-ended conductor electrically connected to a first one of the plurality of first terminals;

a second open-ended conductor electrically connected to a first one of the plurality second terminals, wherein the first open-ended conductor is capacitively coupled to the second open-ended conductor; and

a printed circuit that includes the first and second open-ended conductors.

3. The electrical connector of claim 1, further comprising:

a first open-ended conductor electrically connected to a first one of the plurality of first terminals;

a second open-ended conductor electrically connected to a first one of the plurality second terminals, wherein the first open-ended conductor is capacitively coupled to the second open-ended conductor; and

wherein the first and second terminals are arranged to provide a near-end crosstalk (NEXT) compensation stage and the first and second open-ended conductors are arranged to provide a different NEXT compensation stage, the NEXT compensation stages being configured to generate compensating signals for substantially canceling or reducing a designated amount of offending crosstalk.
