Abstract
Abstract An optoelectronic assembly which provides for enhanced alignment between the internal components thereof. The assembly includes a housing having a base portion and a cover portion, the housing including therein a circuitized substrate. A pair of optoelectronic devices (transmitter and receiver components) are initially movably (loosely) positioned within the housing. The invention utilizes an alignment member which is secured to the housing while positively engaging the movably positioned devices and precisely align these devices with respect thereto such that these devices are in turn precisely aligned with optic means (e.g., a duplex optical connector) when the optic means is positioned within the alignment member. In one embodiment, the housing is of metallic material while the alignment member is a molded plastic structure. The alignment member may also include shutter means therein for safety purposes.
