Abstract:
A chassis and associated telecommunication circuit card are disclosed. The chassis has heat dissipation and flame containment features while accommodating a high density of the circuitry cards. Embodiments include an inner housing with a double-layer middle floor dividing the chassis into top and bottom chambers. Each layer has partially aligned slots, and an air gap is provided between the two layers. Embodiments also include a double-layer mesh cover with an air gap existing between the two mesh layers. Projections and grooves are provided on the inner surfaces of the inner housing to receive circuit cards having a guide on one edge and a fin on another. The circuit card includes conductor structures such as multiple board layers with paired and segregated conductors. The circuit card also includes some components positioned to cooperate with the ventilation features of the chassis and includes some components chosen for low-power consumption or reduced flammability.
Abstract:
A modular platform is provided. The modular platform includes a modular platform shelf configured to receive modular platform boards, and a dual plenum coupled to the modular platform shelf, the modular platform configured to couple to a plenum portion of a dual plenum of another modular platform or a stand-alone plenum.
Abstract:
A cable management system includes an equipment system, and at least one patch panel having a connectivity interface. The connectivity interface is configured to connect with at least one cable extending from the equipment system. The cable management system also includes a manifold configured to be located between the equipment system and the patch panel. The manifold includes an inlet and an outlet, and the manifold is configured to direct the at least one cable from the equipment system to the connectivity interface.

Abstract:
An air flow distribution system for a telecommunication equipment assembly is disclosed. The telecommunications equipment assembly includes a chassis. The chassis is formed by wall panels and includes a first side, a second side, a bottom end section, a top end section, electronic apparatuses regions and a plenum region having plenum region boundaries. The telecommunication equipment assembly also includes a first side air input port and a second side air input port in the bottom end section of the chassis. The input ports permit cooling air to be drawn into the chassis. An output port is provided in the top end section of the chassis. A fan holder is located along one of the plenum region boundaries. The fan holder receives a fan to facilitate air movement in conjunction with the plenum region. The air movement includes movement along air flow paths through the electronic apparatuses regions. The electronic apparatuses and plenum regions are located above the input ports and below the output port. The electronic apparatuses regions border another of the plenum region boundaries.
Abstract:
Retarding a fire condition of a telecommunications component mounted on a module to be inserted into a telecommunications box is provided. The module may have a planar surface having a first side and a second side generally opposed to the first side. A ventilator provides a cross air flow generally in a direction from the first side to the second side. A first opening in the telecommunications box in an area adjacent of the first side of the planar surface forms a substantial portion of the cross air flow emanating from the first side. A second opening in the telecommunications box arranged in an area adjacent to the second side of the planar surface exhausts the cross flow air, such that the cross flow air sub-stantially retards the fire condition. An air flow guide is provided to simulate an air resistance of a module.
Abstract:
A distribution cabinet (1) for accommodating weak-current distribution installations, in particular for arranging outdoors, having a base box (2), an outer cabinet body (3) with at least one door (4), a cabinet cover (5), and an inner installation frame (6), the installation frame (6) being made up of profile sections (50), of which the cross-sectional shapes has two insertion pockets (51a,b), of which the insertion directions (52a,b) run at right angles to one another.
Abstract:
A subassembly includes a plurality of card guides formed to receive card assemblies and also to conduct air for cooling purposes to improve cooling of components on the card guide. The card guides are particularly formed to place the cards in a location to facilitate airflow and to more evenly distribute the airflow. The invention further includes a method for designing the card guides to achieve the stated functionality. The method of designing the card guides includes determining a first and a second volume of space that is desired in relation to the amount of expected heat that is to be generated within the first and second volumes of space.
Abstract:
A frame enclosure for use with electrical communication devices includes joined front and rear cabinets. Patch connectors are mounted in the front cabinet on a divider wall separating the front cabinet into separately accessible first and second compartments, each accessible through a separate, lockable door. External conductors pass through one side of the front cabinet and are terminated on one side of the electrical connectors in a patch field mounted on the divider wall. Conductors from electrical devices in the rear cabinet are engagable with the opposite end of the connectors in the other front compartment after passing through aligned apertures in the cabinet. Industry standard rack mounts are provided in the front and rear cabinets for mounting the electrical connectors and the electrical components in a vertically extending orientation to minimize overall cabinet depth. The rear cabinet has pivotal doors on opposite ends allowing access to the front and rear ends of each electrical device. An optional heat removal device is mounted on the rear cabinet for removing heat generated by the electrical devices.
