Abstract: An optoelectronic assembly for providing bidirectional data transmission between fiber optic means (e.g., a pair of optical fibers) and an electrical circuit member (e.g., a printed circuit board). The assembly includes a two-part housing with first and second receptacle sections designed for accommodating a pair of optoelectronic devices. One of these devices serves as a receiver and the other a transmitter. These devices are aligned within the housing and electrically connected to a substrate member (e.g., ceramic) also positioned within the housing. The substrate provides the necessary electrical functioning and is in turn electrically connected (e.g., via conductor pins) to the described circuit member, this connection occurring through an opening within the bottom portion of the two-part housing. The assembly is designed for coupling with individual optical fiber members or, alternatively, with a common duplex connector having optical fibers therein.

Abstract: An optoelectronic assembly (10) for providing bidirectional data transmission between fiber optic means (11) and an electrical circuit member (13). The assembly includes a two-part housing (17) with first and second receptacle sections (23, 25) designed for accommodating a pair of optoelectronic devices (31, 33). One of these devices serves as a receiver and the other a transmitter. These devices are aligned within the housing and electrically connected to a substrate member (27) also positioned within the housing. The substrate provides the necessary electrical functioning and is in turn electrically connected via conductor pins (69) to the described circuit member, this connection occurring through an opening within the bottom portion of the two-part housing. The assembly is designed for coupling with individual optical fiber members or, alternatively, with a common duplex connector having optical fibers therein.

Abstract: Retention apparatus for retaining an object in a predetermined position This retention apparatus seats and holds an object in place with a constantly applied force. In the preferred embodiments the device has two resilient bow-shaped elongated members that outwardly extend on opposite sides of a handle. Actuating the handle in a linear direction causes the object to move in the same direction to the desired location, carrying the resilient members as it does so. At the desired location, the movement of the object is stopped, but further travel of the handle in the same direction is accomplished by deflection of the resilient bow-shaped members which in turn provides the constantly applied biasing force to the object to seat and hold it in place. An embodiment is described for a retention apparatus to seat and hold a double sided printed circuit card in a pair of zero insertion force type edge connectors. In another embodiment, the device seats and holds two mating connector members, such as a receptacle and header which have mating terminals and pins.
