Abstract
An electrical connector with improved crosstalk compensation is disclosed. By including at least one coupling with a different frequency dependency than other couplings in the connector, crosstalk compensation performance is improved over a greater frequency range. The different frequency dependency may, for example, be used to compensate for phase shifts caused by distances between compensation circuitry and the plug/jack interface. Embodiments for decreasing these distances are also disclosed.
Claims28
A communication jack comprising:
- plug interface contacts for making electrical contact with plug contacts in a plug, the plug interface contacts and plug contacts introducing crosstalk having an associated first frequency dependency based on a frequency of a communication signal being communicated;
- a plurality of crosstalk compensation zones, wherein at least one of the crosstalk compensation zones comprises a coupling having an associated second frequency dependency that substantially differs from the first frequency dependency.
A communication jack for communicating a signal, comprising:
- a first crosstalk compensation zone for offsetting crosstalk;
- a second crosstalk compensation zone to provide additional compensation to offset a phase-shift effect;
- and
- a third crosstalk compensation zone to provide crosstalk compensation that adjusts with frequency of the signal.
