Abstract:
An intelligent network physical layer management system is provided that includes hardware that tracks the connection of plugs of patch cords in interconnect or cross-connect patching environments. RFID signaling is combined with near-field communication techniques to provide a reliable physical layer management system. In interconnect configurations, RFID tags are associated with switch ports of an Ethernet switch, enabling the system of the present invention to detect patch cord insertion and removal at switch ports and to receive information about the switch ports. 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.
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:
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:
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:
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 cable management system for a network cabinet has first and second server equipment rails, first and second air dams, and a front cable support. The server equipment rails are mounted to a base frame of the network cabinet such that the server equipment rails extend from the base frame towards a front of the network cabinet. The air dams are mounted to the base frame of the network cabinet such that the air dams extend from the base frame towards opposing sides of the network cabinet. The front cable support has a generally U-shaped tray that is connected to the first and second server equipment rails such that the tray extends across a front of the network cabinet, transverse to the server equipment rails.

Abstract:
A communications cable having a plurality of twisted pairs of conductors and various embodiments of a metal foil tape between the twisted pairs and a cable jacket is disclosed. In some embodiments, the metal foil tapes include a cut that creates discontinuous regions in a metal layer of the metal foil tapes. When the metal foil tapes are wrapped around the cable core, the discontinuous regions overlap to form at least one overlapping region. The cuts are formed such that overlapping region is small and limits current flow through the metal foil tapes, thereby minimizing alien crosstalk in the communications cable.

Abstract:
Disclosed herein are various implementations of communications connectors. In some implementations, a communications plug may include a housing and a body positioned in the housing. A flexible printed circuit board (PCB) may be wrapped at least partially around the body, a and a plurality of metal contact pads may be positioned on the flexible PCB to mate with plug interface contacts (PICs) of a communications jack when the communications plug is inserted into the communications jack.
