20090258541ASYMMETRIC CROSSTALK COMPENSATION FOR IMPROVED ALIEN CROSSTALK PERFORMANCE - Methods and systems for compensating for alien crosstalk generated by one or more of a plurality of wire pairs in a telecommunications jack are disclosed. One method includes positioning a crosstalk compensation arrangement relating to crosstalk across at least a first wire pair and a second wire pair on a circuit board within a telecommunications jack. The method also includes altering the crosstalk compensation arrangement to accommodate at least one zone of crosstalk compensation having an asymmetric capacitive coupling between a first wire pair and a second wire pair to reduce alien crosstalk generated from one of the first and second wire pairs. Specific jacks and compensation arrangements are disclosed as well.10-15-2009
20090275236FAR END CROSSTALK COMPENSATION - Methods and systems for providing crosstalk compensation in a jack are disclosed. According to one method, the crosstalk compensation is adapted to compensate for undesired crosstalk generated at a capacitive coupling located at a plug inserted within the jack. The method includes positioning a first capacitive coupling a first time delay away from the capacitive coupling of the plug, the first capacitive coupling having a greater magnitude and an opposite polarity as compared to the capacitive coupling of the plug. The method also includes positioning a second capacitive coupling at a second time delay from the first capacitive coupling, the second time delay corresponding to an average time delay that optimizes near end crosstalk. The second capacitive coupling has generally the same overall magnitude but an opposite polarity as compared to the first capacitive coupling, and includes two capacitive elements spaced at different time delays from the first capacitive coupling.11-05-2009
20090318028Connecting Hardware With Multi-Stage Inductive And Capacitive Crosstalk Compensation - A connector and method of crosstalk compensation within a connector is disclosed. The method includes determining an uncompensated crosstalk, including an uncompensated capacitive crosstalk and an uncompensated inductive crosstalk, of a wired pair in a connector. The uncompensated crosstalk includes common mode and differential mode crosstalk. The method includes applying at least one inductive element to the wired pair, where the at least one inductive element is configured and arranged to provide balanced compensation for the inductive crosstalk caused by the one or more pairs. The method further includes applying at least one capacitive element to the wired pair, where the at least one capacitive element is configured and arranged to provide balanced compensation for the capacitive crosstalk caused by the one or more wired pairs.12-24-2009
20100167589TELECOMMUNICATIONS JACK WITH ADJUSTABLE CROSSTALK COMPENSATION - Methods and systems for compensating for crosstalk in a telecommunications jack are disclosed. One method includes manufacturing a circuit board having a zone of crosstalk compensation between a first wire pair and a second wire pair, the zone of crosstalk compensation including a capacitive coupling connected between the first wire pair and the second wire pair and a second capacitive coupling selectively connectable in parallel with the capacitive coupling. The method further includes determining a crosstalk value generated by the jack including the manufactured circuit board. The method also includes, upon determining that the crosstalk value is outside of a crosstalk pass band, adjusting the zone of crosstalk compensation by altering an electrical connection between the second capacitive coupling and the capacitive coupling after the circuit board has been manufactured.07-01-2010
20110201236Plug Assembly for Telecommunications Cable - A plug assembly includes a sleeve and a connector assembly. The sleeve includes a first axial end portion and a second axial end portion. The second axial end portion defines a plurality of channels. The connector assembly is engaged to the second axial end portion of the sleeve. The connector assembly includes a connector body, a plurality of contacts and a plug. The plurality of contacts is disposed in the connector body. Each of the plurality of contacts includes a first end and a second end. The first ends of the plurality of channels are disposed in the plurality of channels of the sleeve. The plug is engaged to the connector body. The plug includes a plurality of grooves through which the second ends of the plurality of contacts are accessible.08-18-2011
20110318965TELECOMMUNICATIONS DEVICE - The present disclosure relates to a telecommunications jack including a housing having a port for receiving a plug. The jack also includes a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing, and a plurality of wire termination contacts for terminating wires to the jack. The jack further includes a circuit board that electrically connects the contact springs to the wire termination contacts. The circuit board includes a multi-zone crosstalk compensation arrangement for reducing crosstalk at the jack.12-29-2011
