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, 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.

Abstract: 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: An intelligent network patch field management system and specialized cross-connect cable are provided to help guide, monitor, and report on the process of connecting and disconnecting patch cords plugs in a cross-connect patching environment. The system is also capable of monitoring patch cord connections to detect insertions or removals of patch cords or plugs. The cross-connect cable is provided with LED's in both of the cable plugs. When only one plug of the cross-connect cable is plugged into a port, the LED associated with that plug is switched out of the circuit, while the LED in the unplugged plug remains in the circuit and can still be illuminated by the system.

In cross-connect configurations, RFID signaling is used to track the connections of patch cords between two patch panels. Systems according to the present invention avoid the problems associated with traditional galvanic connections previously used for tracking patch cord connections. An alternative common-mode system is also described.
