Abstract:
An optical subassembly for reducing undesired electromagnetic interference (EMI), comprising:an optical package comprising a conductive enclosure having an optically transmissive port, an optoelectronic transmitting element mounted within said optical package;a plurality of signal pins, electrically isolated from said conductive enclosure and extending thereftrough to provide electrical signals to said optoelectronic transmitting element;a non-electrically conductive housing having an electrically conductive surface configured to receive said optical package, said electrically conductive surface acting to couple an optical signal from said optical package to an optical fiber carried by an optical connector wherein said electrically conductive surface and said optical package are electrically connected and achieve approximately the same ground potential in order to provide a reduced emissions aperture; andsaid non-electrically conductive housing is made of a non-electrically conductive material and the electrically conductive surface of the housing is formed out of a layer of conductive material .
