Methods and apparatus for fiber-optic modules with shielded housing/covers having a front portion and a back portion

摘要

A fiber-optic module having a housing/shielding unit and a module chassis frame having optical, electrical and electro-optical components. The housing/shielding unit functions both as a protective outer housing and an electromagnetic shield. The housing/shielding unit includes forward fingers and backward fingers. The forward fingers provide an EMI seal around an opening in a bezel, face-plate, back-plate, wall, or panel of a host system and thereby can ground the housing/shielding unit to a chassis ground. The backward fingers can contact host tabs of the host system and can also thereby ground the housing/shielding unit to a chassis ground. The module chassis frame may be formed of a conductive material and can be grounded as well through a host system faceplate or otherwise to the chassis ground.
