Abstract:
A cable management assembly that mounts cables to a ladder rack. The cable management assembly includes a thermal expansion block, a cable attachment beam, and a bracket. The thermal expansion block is positioned on a ladder rung of the ladder rack. The thermal expansion block has a top, a bottom, a first side, a second side, and ends. The first side and the second side of the thermal expansion block have an opening there through that receives the cable attachment beam. The bracket secures the thermal expansion block and attached cable attachment beam to the ladder rung.
Abstract:
Various implementations of epoxy transitions for fiber optic modules are disclosed. As disclosed herein, a fiber optic module system may include a fiber optic module holding a plurality of multi-fiber adapters at a front of the fiber optic module, a multi-fiber cable, and an epoxy transition to transition the multi-fiber cable to a plurality of individual optical fibers inside the fiber optic module. The epoxy transition may be filled with an epoxy to secure the individual optical fibers inside the epoxy transition.
Abstract:
Examples disclosed herein relate to airflow control in data centers utilizing hot aisle containment. Consistent with some embodiments disclosed herein, a first differential pressure sensor may be located in a contained hot aisle in a data center and a second differential pressure sensor may be located in an above-ceiling hot air return plenum connected to the contained hot aisle. Pressure sensor data obtained from the differential pressure sensors may be used to maintain a near-neutral pressure in the contained hot aisle and a set negative pressure in the hot air return plenum.
Abstract:
A communications cable (22) having a plurality of twisted pairs (26) of conductors and various embodiments of a metal foil tape (34) between the twisted pairs (26) and a cable jacket (33) is disclosed. The metal foil tapes (34) include a cut (37) that creates discontinuous regions (38) in a metal layer (35) of the metal foil tapes (34). When the metal foil tapes (34) are wrapped around the cable core (23), the discontinuous regions (38) overlap to form at least one overlapping region. The cuts (37) are formed such that overlapping region is small and limits current flow through the metal foil tapes (34), thereby minimizing alien crosstalk in the communications cable (22).
Abstract:
At least some embodiments of the present invention relate to the field of optical fiber splicing and the evaluation of resulting splice joints. In an embodiment, the present invention is an apparatus for evaluating the integrity of a mechanical splice joint, and comprises a light source, digital video camera, digital signal processor, and visual indicator, wherein the apparatus connects to the test connector and the digital signal processor analyzes digital images of the scatter light from at least a portion of the test connector.
Abstract:
A wire harness assembly system (50) is disclosed. The wire harness assembly system (50) includes a at least one grid tile (60) designed to receive repositionable accessories (110, 150; 110, 160) to route wires along the grid tile (60). The at least one grid tile (60) includes a plurality of keyed holes (70) extending from the top (62) of the grid tile, through the grid tile, to the bottom (64) of the grid tile. The at least one grid tile (60) also includes a locking surface on the bottom (64) of the grid tile. The locking surface complements the plurality of keyed holes (70) to receive the repositionable accessory (110, 150; 110, 160) and to maintain the repositionable accessory in a locked position.
Abstract:
The present invention is directed toward a terminal marker (240) used to identify a terminal block (220). The terminal marker (240) includes a front having a print surface, a back, sides, and flexible legs. The flexible legs can be positioned in a natural state for installation in the terminal block (220) or a compressed state for obtaining a marking from a printer. In the natural state, the flexible legs extend at an angle with respect to the print surface of the terminal marker (240). In the compressed state, the flexible legs extend outward beyond of the sides of the terminal marker (240).
Abstract:
Embodiments of the present invention generally relate to the field of data center cooling and energy management. In an embodiment of the present invention, multiple PODs within a data center are controlled by a controller via active dampers.
Abstract:
The present invention is directed to a split cable gland with a first body member and a second body member. The first and second body members each have a main section and a threaded shaft extending from the main section. The inner surface of each main section has vertical slots. The split cable gland also includes gasket members with a plurality of outwardly extending ribs. The outwardly extending ribs are positioned within the vertical slots in the main sections. The first and second body members surround the cable extending through the opening in a cabinet to create a seal and strain relief arrangement around the cable.
Abstract:
A communication connector has a housing for receiving a communication plug, a printed circuit within the housing, a switch which actuates the printed circuit board, and a translating crossbar which engages the switch. The printed circuit board is moved dependent upon a type of plug inserted. The movement of the circuit board can help to selectively engage one of two sets of circuit traces and groupings of contacts.
