An electromagnetic interference (EMI) gasket system which segregates EMI sensitive circuits from EMI generating circuits is disclosed. The gasket system includes a pair of deflectable leg members disposed relative to each other, which deflect vertically and horizontally when said gasket system is positioned between two opposing substrates and the substrates are drawn together. The leg members provide dual contact with one of the substrates to ensure EMI attenuation without any compression of said gasket.

Gasket system for EMI isolation

An optical network unit for field installation adjacent to an optical fiber transmission line, for separating multiplexed video and telephony signals for delivery to subscribers residences as electrical signals over metallic drop cables, has a hollow housing formed of heat-conductive material. The unit has a sealing front cover and rear cover, a cable entrance port for cable connections, and a backplane assembly mounted in the housing which incorporates optical-to-electrical signal conversion components and connectors for electrical signals. Slots are formed in the interior surfaces of the housing for positioning a plurality of printed circuit board cards for sliding installation into electrical contact with the backplane assembly. Internal fins each protruding from the housing into its hollow interior adjacent to one of the printed circuit board cards, promote heat dissipation from the cards via the internal fins to the exterior walls of the housing for cooling by external cooling fins exposed to the ambient atmosphere.
