Abstract:
An indoor rated communications cable includes a communications carrying medium surrounded by a jacket. A material used to form the jacket is a polymer including a microencapsulated ammonium octamolybdate (AOM) additive therein. In some embodiments, the polymer may include polyvinyl chloride (PVC), fluorinated ethylene propylene (FEP) or polyolefin (PO). One or more additional flame retardants may also be added to the polymer. The communications cable may be a twisted pair, fiber optic or coaxial cable. The present invention also provides a method of forming the communications cable.
Abstract:
An inline cable connector assembly connects one or more twisted pairs of wire leads of a first cable to one or more twisted pairs of wire leads to a second cable. The assembly includes first and second terminal housing parts, first and second wiring caps, and double ended insulation displacement contacts within the connector assembly.
Abstract:
A network consolidation point has a passive coupler and an active converter. The passive coupler is configured to couple a first backbone-coupled, four pair Ethernet cable to a communications outlet-coupled four pair Ethernet cable. The active converter is configured to couple a second backbone-coupled, four pair Ethernet cable to a first communications outlet-coupled, single pair Ethernet cable. The active converter converts data transmitted over the backbone-coupled, four pair Ethernet cable to data transmittable over the communications outlet-coupled, single pair Ethernet cable.
Abstract:
A cable tray includes first and second opposite tray walls and at least one divider arrangement between the tray walls. The divider arrangement includes first and second divider walls joined to each other with a cooling volume between them. A first cable channel is defined between the first tray wall and the first divider wall. A second cable channel is spaced from the first cable channel by the cooling volume and is defined between the second divider wall and at least one of the second tray wall or an additional divider wall. The tray can be used in methods of laying cable. The tray can be part of a ladder rack.
Abstract:
A method and reel design enables blowing cable from a reel into a mid-span access point within a cable conduit. The cable reel includes a central hub, a first flange located proximate one edge of the central hub, a second flange located proximate an opposite, second edge of the hub, and a third flange located between the first and second flanges. A continuous communications cable has first and second portions spooled on first and second reel sections. The technician inserts a first end of the communications cable into a mid-span opening in the conduit, so that the first end of the communications cable is directed toward the first end of the conduit. The first portion of cable is blown off of the first reel section. The technician inserts a second end of the communications cable into the opening in the conduit so that the second end of the communications cable is directed toward the second end of the conduit. The second portion of cable is blown off of the second reel section. Then, a mid-portion of the communications cable is separated from the third flange of the cable reel and resides proximate the opening in the conduit.
Abstract:
A hinge assembly for pivotally coupling a door to a telecommunications chassis includes a hinge structure configured to attach the door to the telecommunications chassis, the hinge structure defining a door pivot point and a hinge pivot point that is spaced from the door pivot point, wherein a door coupled by the hinge structure to the telecommunications chassis can pivot with respect to the hinge structure independent of a pivoting motion of the hinge structure with respect to the telecommunications chassis, wherein the hinge structure further defines at least a portion of a pivot limiting structure spaced from the hinge pivot point, the portion of the pivot limiting structure defined by the hinge structure being configured to interact with the telecommunications chassis in limiting the pivoting motion of the hinge structure.
Abstract:
A communications patching system includes a rack controller and a controller power extender. The controller power extender operates to extend capabilities of the rack controller that monitors one or more patch panels via a panel bus. In certain examples, the rack controller is connected between the rack controller and the panel bus and enables the rack controller to support an increased number of patch panels by preventing a voltage drop at patch panels located far from the rack controller.

Abstract:
A superluminal antenna element having a transmission line feed, and an array comprising a plurality of such antenna elements, is presented. In one example, the antenna element includes a dielectric base portion having a cutout area, a mode transition element coupled to the cutout, a stripline transmission line connected to the mode transition, and a dielectric radiator element disposed within the cutout. The cutout of the dielectric base portion has first and second pluralities of steps arranged in opposing pairs. The mode transition element is located below and coupled to the cutout area of the dielectric base portion. The dielectric radiator element is mounted within the cutout area in an opposing pair of steps. Imposing a time-varying signal on the dielectric radiator element by way of the transmission line, mode transition element, and stepped cutout induces a polarization current in the dielectric radiator element.
Abstract:
A fiber optic lane changer includes a first and a second connector. A plurality of lane changer transmission paths include first ends received within the first connector and second ends received within the second connector. The first ends are arranged in respective ones of a first subset of a plurality of optical interface positions in a standardized connector configuration, and the second ends are arranged in respective ones of a second subset of the plurality of positions. In certain embodiments, the plurality of lane changer transmission paths have first ends that are aligned to optically couple with respective ones of the eight outermost optical transmission paths of the first connector. At least one of the lane changer transmission paths may have a second end that is aligned to optically couple with one of the four innermost optical transmission paths of the second connector.
