Patent ID: 7543997

Claim:
An electromagnetic interference (EMI) system for use with an optical transceiver module, the EMI system comprising: at least a first EMI device being configured to be movably disposed in a housing of the optical transceiver module, the housing comprising an electrically conductive material, the first EMI device comprising an electrically conductive first spring structure, wherein when the first EMI device is movably disposed in the module housing, multiple respective locations on the spring structure are in contact with multiple respective locations on the module housing to provide multiple respective electrical pathways between the spring structure and the module housing, the module housing having at least a first port holder formed therein, the first port holder being configured to receive and hold a first fiber optic port, the first fiber optic port comprising an electrically conductive material; and wherein when the first EMI device is movably disposed in the module housing and the first fiber optic port is held in the first port holder, multiple locations on the first spring structure are in contact with multiple respective locations on the module housing to provide multiple respective electrical pathways between the spring structure and the port, and when the first spring structure is movably disposed within the module housing, the first spring structure is loaded via the contact between first spring structure and the module housing, the loading of the first spring structure ensuring that contact is maintained between the first spring structure and the module housing and between the first spring structure and the first port, wherein the first port holder is configured to hold the first port in a floating arrangement that provides the first sort with some freedom to move, and wherein when the first EMI device is movably disposed in the module housing and the first port is held in the first port holder, movement of the port in the first port holder results in movement of the first EMI device in the module housing.
