Abstract:
A telecommunications chassis, module, and repeater circuit for use with signals having data rates including STM-1 (155.52 megabits per second) are disclosed. The chassis provides structures for establishing shielding and heat dissipation for the circuitry modules it contains including an outer and an inner Faraday box with an integrated ventilation pattern for circulating air. The module provides its own structures for establishing shielding and heat dissipation including a Faraday box and a ventilation pattern. The repeater circuit provides the ability to bridge a data signal between a monitor jack of one device and a higher signal level input jack of another device through multiple amplification stages and circuit board structures. The telecommunications chassis, module, and repeater circuit can be used in conjunction.
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.

The guide includes an opening that at least partially aligns with slots on the adjacent surface of the inner housing. The circuit card includes a finger extending from a faceplate that facilitates insertion and removal of the circuit card relative to the chassis.
Abstract:
A telecommunications equipment enclosure (10) that dissipates into the ambient environment heat internally generated by signal repeater cards and other electronic equipment stored therein, thereby prolonging equipment life and preventing premature failure due to damaging levels of retained heat. Equipment-receiving sleeves (20) are removably arranged concentrically about the interior of a cylindrical housing (12). The housing (12) is fitted with a lid (14) having a cylindrically protruding portion (48). Cooling fins (16) operable to conduct and dissipate heat are attached to the exterior of the housing (12). Each sleeve (20) is able to conduct heat away from the heat-generating equipment received therein, and to transfer the heat along two distinct thermally conductive pathways. Surge protection (60) is provided on a removable circuit board (62) located adjacent each sleeve (20) and replaceable without removing the sleeve (20) or otherwise disrupting functioning of the cards or other electronic equipment.

Abstract:
A communication device includes a number of transmitter/receiver/modem blocks installed in vertical positions. Each of the transmitter/receiver/modem blocks includes a supporting board having a front surface and a back surface, the supporting board including a plurality of fins on the front surface and a plurality of forced air-cooling fans on the supporting board. A front cover encloses the front surface of the supporting board, the front cover and the fins forming a plurality of ducts, the front cover and the front surface forming an internal opening under the fins. A back cover encloses the back surface of the supporting board. First heat-radiating circuit modules are provided at positions adjacent to the fins on the front surface. A second heat-radiating circuit module is provided within the opening. When the forced air-cooling fans operate, the fans produce a flow of air along the plurality of ducts to cool the first heat-radiating circuit modules, and the fans producing a flow of air within the opening to cool the second heat-radiating circuit board.
