  • Patent number: 9755414
    Abstract: An overhead electrical grounding mesh and mechanical grid structure for a data center includes a plurality of orthogonally arranged grid beams. Each of the grid beams is a rigid and electrically conductive grid beam to provide an overhead structure configured to be positioned over electronic equipment in the data center. The grid structure is configured to provide support for electronic equipment connected to the grid structure and to provide support for mechanical equipment in the data center that is connected to the grid structure. The grid structure is further adapted to be electrically coupled to the electronic equipment to provide an electrically conductive ground mesh for the electronic equipment in the data center.

  • Patent number: 8425260
    Abstract: A communications cable for use with a communications connector having eight contacts arranged in a series. The cable has first, second, third, fourth, fifth, sixth, seventh, and eighth wires configured to be connected to first, second, third, fourth, fifth, sixth, seventh, and eighth contacts, respectively, of the series. The fourth and fifth wires are twisted together to form a first twisted wire pair (“twisted pair”). The first and second wires form a second twisted pair. The third and sixth wires form a third twisted pair. The seventh and eighth wires form a fourth twisted pair. The twisted pairs extend alongside one another and are arranged such that the first twisted pair is closer to the second and third twisted pairs than to the fourth twisted pair, and the second twisted pair is closer to the first and fourth twisted pairs than to the third twisted pair.

  • Publication number: 20120202389
    Abstract: A spring assembly for a communications jack including a plurality of jack contacts each electrically connectable to a corresponding plug contact of a communications plug. First and second jack contacts carry a first differential signal. Fifth and sixth jack contacts carry a second differential signal. The jack contacts carrying the first differential signal are adjacent a third jack contract and the jack contacts carrying the second differential signal are adjacent a fourth jack contract. For each jack contact, the assembly has a conductive spring member electrically connected to the jack contact that biases the jack contact against a corresponding plug contact. To reduce crosstalk, the spring members connected to the first and second jack contacts are each capacitively coupled to the fourth jack contact, and the spring members connected to the fifth and sixth jack contacts are each capacitively coupled to the third jack contact.

  • Patent number: 7824231
    Abstract: A communications outlet includes eight outlet tines positioned adjacent to one another and define four pairs of outlet tines. The fourth and fifth outlet tines define a first pair, the first and second outlet tines define a second pair, the third and sixth outlet tines define a third pair, and the seventh and eighth outlet tines define a fourth pair. Each outlet tine has a free end near which a plug tine is adapted to contact the outlet tine and each outlet tine has a fixed end coupled through a corresponding conductive tine to a corresponding electrical contact. The communications outlet includes an internal crosstalk compensation stage having a plurality of conductive fingers. Each conductive finger is physically connected to a corresponding one of the outlet tines proximate the free ends of the tines.

  • Patent number: 7278879
    Abstract: A connector isolation station system includes ports to receive connectors and includes shield members. The shield members have material properties to substantially shield, attenuate, absorb, diminish, or otherwise hinder or at least partially block wireless signals and noise from impinging upon or otherwise interfering with signal transmissions occurring through the connectors located in the connector isolation station. For instance, transmissions through adjacent connectors are substantially prevented from interfering with one another.

  • Patent number: 7273396
    Abstract: Implementations of a shielded connector system involve connector isolation shielding using shield enclosures to reduce crosstalk and noise transmitted between adjacent signal cable connectors. These implementations allow for manufacture of new equipment and also retrofitting of existing equipment for connector isolation shielding using standard connector configurations without specialized labor intensive terminations for cable and for connectors required of conventional approaches.
