Optical transceiver with enhanced shielding and related methods

Abstract

An optical transceiver module includes a transmitter portion and receiver portion positioned within a housing with an EMI shield therebetween, and wherein the transmitter and receiver portions include respective substrates, or circuit boards, with opposing and spaced apart major surfaces. The port density, when using a plurality of such modules, is increased, while providing enhanced EMI shielding. Each circuit board may include a ground plane and have a plurality of generally L-shaped conductive leads extending outwardly from the respective circuit boards. The optical transmitter and optical receiver portions each preferably further comprise at least one active component mounted on the first major surfaces. Accordingly, these active components face one another. The optical transmitter portion preferably further includes an optical emitter connected to an end of the first circuit board, and the optical receiver portion preferably further comprises an optical detector carried by an end of the second circuit board. In addition, the housing preferably includes an integrally formed transverse bulkhead with respective openings receiving the optical emitter and the optical detector. The transverse bulkhead also defines a forward cavity for receiving an optical fiber connector. The housing may have a generally rectangular elongate shape and have a series of longitudinally extending slots therein. The EMI shield, and first and second substrates or circuit boards may be received in these lots for convenience of assembly.
