Abstract:
The invention relates to a module (10) essentially comprised of a module housing (1) into which a lead frame (3), on which an electro-optical converter (5) is mounted, is inserted and the interior of the module housing (1) is filled by a transparent casting compound. A plug receptacle (7) is shaped on the outer housing wall and comprises a defined outer contour. An optical waveguide piece (6) is located inside the plug receptacle (7). Said optical waveguide piece, starting from the surroundings of an outer surface of the plug receptacle (7), extends through the inside of the plug receptacle (7) and a housing opening until it reaches the inside of the housing, and is optically coupled to the electro-optical converter (5). An optical waveguide plug (20) that interacts with the module (10) is provided with a socket-shaped plug section (27) that corresponds to the plug receptacle (7).
Abstract:
The invention relates to an optical broadband transmission device and distribution method, particularly suitable for multimedia networking in multi-occupancy apartment blocks. An optical fibre (101) is provided as central element connecting a first optical transceiver (102) with a second optical transceiver (103). Data streams between a supply node (104) and a user node (105) can be transmitted by means of said device. According to the above method the transmission rate is typically 100Mbs, whilst a conventional electrical transmission line can achieve only a maximum of 10 Mbs with the same transmission distance (500 to 1000 m).
Abstract:
An electro-optical transmitter and/or receiver module comprising a leadframe (2) and an opto-electrical converter (3,4,9) mounted thereon, whereby said elements are surrounded by a moulded body (8) made of a mouldable material which is transparent to light. A reflector element (7) is arranged in the moulded body (8), enabling deflection of a beam of radiation, which is emitted by an emitter (4) or a received beam of radiation which is to be directed towards a receiver (9), at a specific angle. The module can be used in an electro-optical transmitter and/or receiver unit which is embodied as a sidelooker.

Abstract:
An electro-optical data transmission module comprises at least a first SMT housing (11) and a second SMT housing (13). A surface-emitting laser light emitter chip is accommodated in the first SMT housing (11), and a light-sensitive light receiver chip is accommodated in the second SMT housing (13). By virtue of the modular design which is formed from at least two individual SMT housings, the electro-optical data transmission module can be implemented with a minimum size.
Abstract:
The transceiver includes a transmitting arrangement and an adjacent reception arrangement, which are arranged in such way, that they are optically coupled with an input and output end of a glass fibre. The transmitting arrangement, the reception arrangement, and the input and output end of a glass fibre (20) are arranged optically in series with each other. The devices are arranged preferably in such way, that the maximum of the coupling between the transmitting arrangement and the glass fibre and between the reception arrangement and the glass fibre with respect to lateral displacement, and the fibre axis are aligned.
Abstract:
A plug-in connecting element is used in optoelectrical devices or subassemblies that have optical components and electrical components, and also in a plug-in connector having two plug-in connecting elements of this type. The plug-in connecting element has in a basic body, at least one electrical interface and at least one optical interface, which can be jointly connected in a pluggable manner to a matching plug-in connecting element. The plug-in connecting element is distinguished by the fact that electrical and optical paths are combined by the integration of an electrical interface and an optical interface in one plug-in connecting element.
