Abstract:
In one embodiment, the present invention is a communication connector, comprising a compensation circuit for providing a compensating signal to approximately cancel an offending signal over a range of frequency, the compensation circuit including a capacitive coupling with a first magnitude growing at a first rate over the range of frequency and a mutual inductive coupling with a second magnitude growing at a second rate over the range of frequency, the second rate being greater than the first rate (e.g., the second rate approximately double the first rate).
Abstract:
Embodiments of the present invention are generally related to communication connectors, and more specifically, to communication connectors such as jacks which are compatible with more than one style of a plug. In one embodiment, the electrical and mechanical design of a jack in accordance with the present invention may extend the usable bandwidth beyond the IEC 60603-7-71 requirement of 1000 MHz to support potential future applications such as, but not limited to, 40GBASE-T. In addition, the jack may be backwards compatible with lower speed BASE-T applications (e.g., 10GBASE-T and/or below) when an RJ45 plug is mated to the jack.

Abstract:
The present invention provides an automated system for asset tracking and management and utilizes near field Radio Frequency IDentification (RFID) technology. RFID tags are attached to the assets via a flexible mounting system, and RFID antennas (and corresponding readers) are strategically located in close proximity to read the tags. As applied to a rack or cabinet, near-field antennas are mounted along one of the mounting posts at each rack unit location such that when a piece of equipment (rack mounted or rail mounted) is installed at a particular rack unit space, the tag will be read and registered in an RFID management system. A magnetic field shaping arrangement ensures that crosstalk between adjacent rack positions is prevented. Ferrite elements are used to control the magnetic field.

The present invention generally relates to the field of network communication, and more specifically to networks for crosstalk reduction/compensation and communication connectors which employ such networks. In some embodiments, the present invention employs an orthogonal network implemented within a communication jack to compensate for crosstalk which occurs within a communication plug and at the plug/jack interface.
Abstract:
A communication connector comprising plug interface contacts having a plurality of conductor pairs, and corresponding cable connector contacts. A printed circuit board connects the plug interface contacts to respective cable connector contacts. The printed circuit board includes circuitry between a first conductor pair and a second conductor pair. The circuitry has a first mutually inductive coupling between a first conductor of the first conductor pair and a first conductor of the second conductor pair, a first capacitive coupling between the first conductor of the first conductor pair and the first conductor of the second conductor pair. The first capacitive coupling is approximately concurrent with the first mutually inductive coupling. A shunt capacitive coupling connects the first conductor of the second conductor pair to a second conductor of the second conductor pair.

Abstract:
A communication jack having crosstalk compensation features for overall crosstalk interference reduction is disclosed. In one embodiment, the jack is configured to receive a plug to form a communication connection, and comprises jack contacts disposed in the jack, with each contact having at least a first surface and a second surface. Upon the plug being received by the jack, the plug contacts interface with the first surface of the jack contacts. The jack further includes a first capacitive coupling connected between two pairs of jack contacts to compensate for near end crosstalk, with the first capacitive coupling being connected to the pairs of jack contacts along the second surface adjacent to where the plug contacts interface with the jack contacts. A far end crosstalk compensation scheme is also set forth.
