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.
Claims8
A plug-jack combination comprising a jack and a plug containing plug contacts, the jack comprising:
- a plurality of plug interface contacts in the jack, the plug contacts contacting the plug interface contacts at plug/jack interfaces of the plug interface contacts when inserted into the jack;
- a compensation zone adjacent to the plug interface contacts;
- and
- a crosstalk zone positioned farther from the plug/jack interfaces than the compensation zone,
- wherein at least one of the compensation or crosstalk zones contains at least two compensation structures, a first compensation structure providing a first compensation coupling having a first magnitude at any particular frequency of normal operating frequencies of the jack and a second compensation structure providing a second compensation coupling having a second magnitude at the same particular frequency, and
- wherein the ratio of the first magnitude to the second magnitude varies with frequency.
A plug-jack combination comprising a jack and a plug containing plug contacts, the jack comprising:
- a plurality of plug interface contacts in the jack, the plug contacts contacting the plug interface contacts at plug/jack interfaces of the plug interface contacts when inserted into the jack;
- a compensation zone adjacent to the plug interface contacts and having two compensation zone pairs connected to two pairs of the plug interface contacts;
- and
- a crosstalk zone positioned farther from the plug/jack interfaces than the compensation zone and having two crosstalk zone pairs connected to the two compensation zone pairs,
- wherein a first rate of coupling magnitude increase in dB between the two pairs of the plug interface contacts and between the plug contacts vs. frequency is relatively constant, a second rate of coupling magnitude increase in dB between the two crosstalk zone pairs vs. frequency is relatively constant, and a third rate of coupling magnitude increase in dB between the two compensation zone pairs vs. frequency is relatively lower than the first and second rates.
A plug-jack combination comprising a jack and a plug containing plug contacts, the jack comprising:
- a plurality of plug interface contacts in the jack, the plug contacts contacting the plug interface contacts at plug/jack interfaces of the plug interface contacts when inserted into the jack;
- a compensation zone adjacent to the plug interface contacts and having two compensation zone pairs connected to two pairs of the plug interface contacts;
- and
- a crosstalk zone positioned farther from the plug/jack interfaces than the compensation zone and having two crosstalk zone pairs connected to the two compensation zone pairs,
- wherein a first rate of coupling magnitude increase in dB between the two compensation zone pairs vs. frequency is relatively constant, and a second rate of coupling magnitude increase in dB between the two crosstalk zone pairs vs. frequency is relatively higher than the first rate.
