The invention relates to a method and to a circuit configuration for adjusting the voltage level for the electrical data transmission between a transmitting component and a receiving component of one or different assemblies. According to the invention, the voltage level is increased step-wise or continuously until the required value for the correct representation of the signals to be transmitted is reached in the receiving component. Increase of the voltage level is stopped by the transmission of respective information. The inventive method and circuit are advantageous in that the minimum voltage level required for the transmission of data can be precisely adjusted. Power loss can be thereby reduced and adjacent channel interferences through high voltage levels can be reduced to a minimum.

Method and circuit configuration for adapting the voltage level for the transmission of data

The switching network serves for the transmission of digital data signals within a broadband communication system. This switching network is thereby constructed of individual switching elements (KE) that form at least one multi-stage funnel due to a connection to one another. The section for the assemblies of the switching network is selected such that at least one complete funnel is accommodated on the respective assembly. The respective assembly thereby has its external data inputs provided with unidirectionally designed optical/electrical transducers (OML-E) and has its external data outputs provided with unidirectionally designed electrical/optical transducers (OML-S).

Switching network for a broadband communication system

A device for transmitting high-frequency signals over data lines which are fixed on conventional circuit boards at a specific angle to optical fiber bundles forming the circuit boards.

Device for transmitting high-frequency communication signals and method for manufacturing the device

The invention relates to an opto-electric module, comprising a printed circuit board (L) which as an electrical interface has a number of plug-in contacts (SK) running parallel in the area of a first face for directly plugging the module into an assembly. As an optical interface, said printed circuit board is also connected to an optical element (OE) in the area of a second face. The component side and the back of said printed circuit board are also covered at least partly by a housing part (GK, KK).
