The patch panel assembly includes a drawer and a patch panel pivotally mounted to the drawer. The drawer has a pair of sidewalls and a cable tray positioned therebetween. The cable tray has a plurality of slide locks including lock releases that allow the cable tray to move between a closed position and an open position with respect to the sidewalls. The cable tray also has a plurality of retainer clips that allow the patch panel to move between an upright position and a rotated position with respect to the cable tray.

A communications connector with a flexible printed circuit board is provided. The flexible printed circuit board is electronically and mechanically connected to the plug interface contacts of the jack near the plug/jack interface, in order to provide effective crosstalk compensation. The flexible printed circuit board has fingers at one end allowing it to flex as individual plug interface contacts are depressed when a plug is installed into the jack. A second end of the flexible printed circuit board has through holes for accepting insulation displacement contacts. The second end of the flexible printed circuit board may be rigidly supported, to allow insertion of the insulation displacement contacts. Various designs for capacitive and/or inductive couplings are provided, resulting in improved crosstalk performance.

A wall mount cabinet is disclosed. The wall mount cabinet includes a rear section having a first end and a second end, and a front section hingedly connected to the rear section at a pivot point. The rear section has a cutout area adjacent the first end, and the cutout area allows access for cables to enter the cabinet. The pivot point is adjacent the cutout area and the first end of the rear section. The cutout area allows cables to rotate about the pivot point when the cabinet is moved from a closed position to an open position.

Systems and methods for directing and facilitating the installation and revision of communications connections use indicators on active jacks to inform installers and revisors of installation and revision instructions forwarded by a network installation, monitoring, and/or revising system. Cross-connect and interconnect systems utilize patch panels populated with active jacks having indicators for facilitating installation and revision of cabling.

The embodiments provide a barb assembly for use with a cable duct component to oppose removal of a cable duct section from the cable duct component. The barb assembly can comprise a releasable assembly for applying a force to a barb and, responsive to the application of the force, for moving the barb and one or more barb arms from an unengaged position to an engaged position without the use of tools. The barb assembly and/or cable duct component can also comprise a spring bias, which can bias the releasable assembly to the unengaged position upon actuating the releasable assembly to the unengaged position. The embodiments also provide methods of installing cable duct components and systems with the above-described features.

A network cable jack includes a printed circuit board (PCB) for balancing both inductive and capacitive coupling. Using a PCB allows compact trace paths to be formed without significantly increasing manufacturing costs. By including on each trace path two distinct inductance zones separated by a neutral zone, significant gains in degrees of freedom are achieved for designing PCB trace patterns in which a pair of inductive coupling zones jointly offset the inductive coupling caused by a specification plug and the jack contacts, both in magnitude and phase angle. Further, using distinct inductance zones offers more freedom regarding the placement of capacitive plates for use in capacitance balancing as well as the placement of terminals and insulation displacement contacts. Although the magnitude of a capacitive coupling is determined by the length of the capacitor plates parallel to current carrying traces, the approach allows capacitive and inductive coupling to be balanced independently.

Methods and apparatus for documenting network path connectivity are described that allow a network management system/revision management system (NMS/RMS) to determine what equipment and ports support a network path by interrupting and restoring Power-over-Ethernet (PoE) service on the network path. Upon detecting a loss of PoE service, communication active jacks that support network path connectivity may activate an internal switch that interrupts downstream connectivity. Each communication active jack along the network path may then begin broadcasting a unique message in the upstream direction that is addressed to the NMS/RMS. Upon receiving a unique active jack message, the NMS/RMS may record the information contained within and instruct the communication active jack to reestablish connectivity to the next downstream device. In this manner, as each device along a network path regains connectivity the network path information stored within the NMS/RMS is updated until a complete view of the network path is documented.

An angled patch panel is mountable to a network rack. The angled patch panel includes a patch panel frame, rack mounting members provided on opposite longitudinal ends of the frame, and a plurality of connectors mountable on the frame. The frame has a first panel section and a second panel section angled relative thereto by an obtuse angle between 90° and 180°. The first and second panel sections each define a front surface, and the plurality of connectors are oriented at an acute angle α relative to the front surface of either the first or second panel sections.
