A modular multipurpose telecommunications enclosure has a plurality of walls, to which are removably affixed a plurality of mounting bulkheads. Each mounting bulkhead has a plurality of mounting holes arranged into a specified hole pattern that is configured to receive and mount cameras or other electronics units from various different equipment manufacturers which employ different hole patterns in their mounting kits. The enclosure is made of a high thermal conductivity material such as aluminum to promote convection cooling and employs one or more airflow vents to keep any internal electronics from reaching undesirably high temperatures during operation. The enclosure also features antenna mounting holes to accommodate various wireless communication antennas, as well as a mounting bracket to allow easy installation of the enclosure in a desired location. The enclosure is rugged and durable against the elements to facilitate purposes such as video monitoring of an outdoor area.

A communication system may include a first chassis having first and second side walls and adapted to slidably receive therein a plurality of cassettes. A first cable hanger assembly may have a first side edge hingedly coupled to the first side wall of the first chassis, the first cable hanger assembly including a plurality of first hangers adapted to support cables thereon. An axis of rotation of the first cable hanger assembly may be substantially orthogonal to a direction in which the plurality of cassettes are slideable. The cable hanger assembly may be rotatable from a first position to a second position so that during rotation from the first position to the second position, the plurality of first hangers move toward front faces of the plurality of cassettes.

A fiber distribution hub configured to house a patch panel includes a plurality of walls forming a chamber, a first shelf attached to a first wall of the plurality of walls in the chamber, a first track supported by the first shelf, and a frame body configured to support the patch panel and to be coupled with the first shelf via the first track. The frame body is configured to shift along the first track between a stored position, a front-exposed position, and a back-exposed position.

An outdoor cabinet and a top structure thereof are provided. The top structure of the outdoor cabinet includes a top beam, wherein the top beam is a bending plate; the number of the top beams is at least two, one of two connected top beams is provided with a first locating breach, and the other is provided with a first protruding portion in cooperation with the first locating breach for locating. Compared with that the top beam in the conventional art is a flat plate, the top structure of the outdoor cabinet provided effectively improves the strength of the top beam by designing the top beam to be the bending plate, which improves the strength of the overall top structure, reduces the influence on the hoisting of the outdoor cabinet, and improves the flexibility of the hoisting of the outdoor cabinet.

A utility cabinet includes a housing having an interior compartment, a rear wall, a top wall, a bottom wall, a first side wall, a second side wall, a front opening, and a side opening. A frame is connected to the housing and moveable between a first position where the frame is entirely in the housing and a second position where at least a portion of the frame is outside of the housing. The frame is configured to receive one or more utility components. A front door is connected to the housing and moveable between a closed position covering the front opening and an open position providing access to the front opening. A side door is connected to the housing and moveable between a closed position covering the side opening and an open position providing access to the side opening.

A grounding clip for a plug-in universal (PIU) module enclosure in an optical network element includes a first wing portion shaped to be positioned between and in contact with a first side of a faceplate of the network element and the chassis, a second wing portion shaped to be positioned between and in contact with a second side of the faceplate and the chassis, and a center portion shaped to extend over and to be in contact with the PIU module enclosure when the grounding assembly is installed in the network element. The grounding clip includes an opening through which a fastener electrically and mechanically couples the grounding clip to a printed circuit board (PCB) and to the chassis when installed, the PCB being installed within the chassis and configured to be communicably coupled to a PIU module when the PIU module is installed in the PIU module enclosure.

A ballast system includes a substantially rectangular base with approximate bottom dimensions of a standard International Organization for Standardization (ISO) freight container; base locking units at each corner of the base to be secured to a shelter with approximate dimensions of a standard International Organization for Standardization (ISO) freight container; and extendable arms extending from the base to the ground.

A slide assembly for slidably coupling a telecommunications tray to a telecommunications chassis includes a rail configured for mounting to the chassis, the rail defining a rail sliding cavity flanked by a first detent adjacent a first end and a second detent adjacent a second end of the rail, the rail further comprising first and second chassis mounting features, the first and the second chassis mounting features are oriented with respect to each other such that if two of the same rails are aligned and brought together in a juxtaposed relationship with the first and second chassis mounting features facing each other, the first and the second chassis mounting features can nest relative to each other so as to not increase the total width of the two rails. A guide configured for mounting to the telecommunications tray defines a guide sliding cavity configured to slidably receive the rail such that the rail sliding cavity and the guide sliding cavity face each other, the guide defines a pin connected thereto via a flexible cantilever arm, at least a portion of the pin extending into the rail sliding cavity when the rail and the guide are in a sliding relationship for latching by the first and second detents of the rail in providing two predetermined stop positions for the guide.

A closure (100/200) protects telecommunications circuitry from water and dust. The closure (100/200) includes a base (128) that has a sidewall (134) that extends upwardly from a bottom (118), and the sidewall (134) has at least one cable port (122/222). The closure (100/200) also includes a cover (126) that attaches to the base (128) to close an interior (130) of the closure (100/200). Further, a galvanic anode (124) is removably secured to the sidewall (134) of the base (128) of the closure (100/200) and electronic circuitry (132) is disposed within the interior (130) of the closure (100/200). The electronic circuitry (132) is active electronic circuitry.
