Abstract: 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.

Abstract: An electrical connection system includes various devices and structures for improving alien crosstalk performance in a high density configuration. In certain examples, a plurality of insulation displacement contacts of a connector are arranged at angle and oriented to be symmetrical about an axial of the connector. The connector includes a connector housing and a shield cap configured to at least partially cover the connector housing. The shield cap includes a shield wall and an open side that is not closed by a shield wall. The shield wall exposes a portion of the connector when the shield cap is mounted to the connector housing. When a plurality of such connectors are arranged side by side in a high density configuration, the connectors are aligned such that the open side of the shield cap is arranged close to, or abutted to, the shield wall of the shield cap of an adjacent connector.

Abstract: The present invention relates to methods and systems for minimizing alien crosstalk between connectors. Specifically, the methods and systems relate to isolation and compensation techniques for minimizing alien crosstalk between connectors for use with high-speed data cabling. A frame can be configured to receive a number of connectors. Shield structures may be positioned to isolate at least a subset of the connectors from one another. The connectors can be positioned to move at least a subset of the connectors away from alignment with a common plane. A signal compensator may be configured to adjust a data signal to compensate for alien crosstalk. The connectors are configured to efficiently and accurately propagate high-speed data signals by, among other functions, minimizing alien crosstalk.

Abstract: The present disclosure relates to a telecommunications connector having cross-talk compensations, and a method of managing alien crosstalk in such a connector. In one example, the telecommunications connector includes electrical conductors arranged in differential pairs and a circuit board with conductive layers that provide a cross-talk compensation arrangement for applying capacitance between the electrical conductors. The circuit board includes conductive paths that provide capacitive coupling and a conductive plate that intensifies capacitive coupling of the electrical conductors. In another example, the telecommunications connector is used with a twisted pair system. Capacitances applied by the crosstalk compensation arrangement between electrical conductors associated with the pairs are provided such that, for each differential pair, a magnitude of an overall capacitance at a first electrical conductor of a differential pair is approximately equal to a magnitude of an overall capacitance at a second electrical conductor of the differential pair.
