Abstract: The arrangement has at least two electrooptic transducers (1, 2) with in each case one optically active zone (1a, 2a). Optical connections (12, 14) which are assigned to the transducers are adjacent at a spacing (a). Optical coupling paths (8, 9) run via a coupling device (6) between the connections (12, 14) and the respectively assigned optically active zones (1a, 2a) In order in the case of a very tight spacing (a) to permit a favorable crosstalk response and a cost effective design, the coupling paths (8, 9) run in such a way that the spacing (A) between two optically active zones (1a, 2a) is greater than the spacing (a).

Abstract: The module has a connection port with a lock and a holding sleeve adapted to receive an SC connector. Alignment aids align the connector in such a way that optical conductor ends that extend in a common plane within the connector come to lie in a prescribed position. The module includes a plurality of electrooptical transducers which are assigned to the one connection port and are aligned with the prescribed relative position of the longitudinal plane via waveguides. When the connector pin is inserted, each transducer is individually coupled to a respective end of one of the optical conductors.

Abstract: An electrical unit includes a printed circuit board having a multi-pole plug and a main board having body edges and a plug to be connected to the multi-pole plug in a plug connection. A frame for receiving the printed circuit board has opposed sides and catch lugs being disposed on the opposed sides. The catch lugs have catch elements and the catch lugs are elastically deformed by the body edges upon connection of the plug of the main board to the multi-pole plug. A release lever is supported on the frame and has at least one pressure surface to be pivoted out of a connected position in which the catch elements are latched fixingly to the main board and into a release position in which the at least one pressure surface is braced against the main board for generating a force to undo the plug connection.
