Abstract:
Apparatuses having a plurality of optical duplex and parallel connector adapters, such as MPO connectors and LC adapters, where some adapters connect to network equipment in a network and others to servers or processing units such as GPUs, incorporate internal photonic circuit with a mesh. The light path of each transmitter and receivers is matched in order to provide proper optical connections from transmitting to receiving fibers, wherein complex arbitrary network topologies can be implemented.
Abstract:
A combination outlet capable of accepting a C14 and C20 plug has a central contact retaining portion and a plurality of tabs surrounding the central contact retaining portion. The tabs are configured to move toward and away from a center of the central contact retaining portion such that the tabs engage an inner surface of a housing of the C20 plug and an exterior surface of a housing of the C14 plug.
Abstract:
A modular power distribution system includes using power extension modules and power distribution modules. The power extension modules are configured to route inputted power to another power extension module or a power distribution module. The power distribution modules are configured to route power from a power extension module to one or more racks or cabinets in a data center.
Abstract:
A communications cable has a plurality of twisted pairs of insulated conductors, metal foil tape between the twisted pairs, and a cable jacket are disclosed. The metal foil tape can include a substrate, a metal layer on the substrate, and a triboelectric coating on at least the metal layer of the metal foil tape. The triboelectric coating has a charge affinity closer to a charge affinity of the insulated conductors than a charge affinity of the metal layer to prevent charge build up between the conductors and the metal foil tape.
Abstract:
Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

Abstract:
The present invention generally relates to the field of uninterruptable power supplies (UPSs) and more specifically, to UPSs using supercapacitors (also may be referred to as ultracapacitors) and/or other capacitor and/or battery elements. In an embodiment, a UPS of the present invention can individually regulate the charging of its capacitive elements to avoid overcharging and/or achieve a more efficient charge state.
Abstract:
A communication plug having a plug body and a plurality of contact pairs at least partially within the plug body, the contact pairs including an inherent asymmetric coupling between individual contacts of one of the contact pairs and other individual contacts of another of the contact pairs. Second asymmetric coupling elements are connected between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs. The second asymmetric coupling elements, when combined with the inherent asymmetric coupling, provide a balanced symmetric coupling between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs.
Abstract:
A twinax cable is described. The twinax cable has at least one twinax wire pair with a first shield tape wrapped around it and then surrounded by a second shield tape wrapped around the twinax wire pair and the first shield tape. The shield tapes are wrapped such that the metallic sides of the tape face and make contact with each other.
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.
