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 layered tape having pockets therein is used as part of a communication cable to improve alien crosstalk attenuation. In one embodiment, a single layered tape has an embossed layer bonded to a matrix tape layer having non-continuous conductive traces, with the resulting layered tape reducing alien crosstalk between cables. Pockets resulting from the embossing are filled with a gas such as dry air to decrease the dielectric constant through the effective thickness of the tape. A layered tape may alternatively be provided as a separate tape from a matrix tape, such that coupling between conductive pairs of the cable and the matrix tape is reduced. Decreasing the dielectric constant of materials between adjacent cables also decreases alien crosstalk coupling between the cables.

Abstract: An intelligent network patch field management system is provided that includes active electronic hardware, firmware, mechanical assemblies, cables, and software that guide, monitor, and report on the process of connecting and disconnecting patch cords plugs in an interconnect or cross-connect patching environment. RFID tag integrated chips are used in some embodiments of the system to allow for detection of patch cord insertion and removal at switch ports. RFID tags may also be used to detect users and control access to the network based on the users' levels of authorization. Network access can also be controlled at the outlet jack level. The system is capable of monitoring patch cord connections to detect insertions or removals of patch cords or plugs. In addition, the system can map entire networks.

Abstract: Systems and methods for decreasing alien crosstalk use enhanced patch cords for introducing additional attenuation. The enhanced patch cords are preferably shielded to reduce alien crosstalk down their lengths and also attenuate signals passing therethrough to a greater extent than standard communication patch cords. The interaction of two enhanced patch cords results in two suppression steps for alien crosstalk and only one suppression step for intended signal passing through a communication cable.

Abstract: An Ethernet outlet senses the presence of an Ethernet signal and transmits an Ethernet ID signal in response to the restoration of an Ethernet signal that was interrupted. The sensing circuit is designed to have no detrimental effect on Ethernet signals. Using this system, the locations of Ethernet outlets and network endpoint devices connected to the outlets can be determined following the interruption and reestablishment of network communications. Outlets according to the present invention can be used in copper-based networks or in networks having fiber optic components.

The coupling circuitry is configured for disengaging from said first contact pair and said second contact pair when said second plug is inserted into said housing.

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.

In some embodiments, the present invention is a thermal management system comprising a cabinet-side thermal management system and a server-side thermal management system using moveable thermal components.

Abstract: A communication network device and corresponding patch field system are disclosed. The device includes a port module, ports, and an appliqué attached to a face of the port module. The appliqué includes a printed circuit board (PCB) with conductive pads. A patch cord connects the device with an intelligent patch panel. The patch cord contains at least one system wire. The patch panel is adapted to measure a resistance associated with each port via the system wire. An open circuit indicates that no patch cord is attached to the port, a resistance within a first range indicates that the patch cord is attached only to the port of the intelligent patch panel, and a resistance within a second range less than the first range indicates that the patch cord connects the intelligent patch panel and the device.

Abstract: Alien crosstalk in communication channels is decreased with the use of crosstalk-mitigating materials. Electrical communication cables may be provided with crosstalk-mitigating materials that surround twisted pairs in the cables.

Such a material mitigates the effects of electrical and magnetic fields that would normally lead to alien crosstalk between communication channels.
