Abstract:
1. A data transmission device for high bit-rate data optical signals, especially high bit-rate optical data signals greater than 1 Gbit/s, the device comprising: (a) a backplane, which has a line structure adapted to connect several plug-in positions for several receiver and transceiver cards to each other or to at least one other data processing card; (b) a plurality of receiver and transceiver cards, which are each held in one of the plug-in positions and which each have at least one input port each adapted to connect to a high bit-rate optical data signal, each of the high bit-rate optical data signals being generated by (c) a central selection unit connected to the backplane and having a plurality of input ports; (d) wherein each of the receiver and transceiver cards has at least one output port, to which the relevant high bit-rate data signals can be fed, the output port being connected via a serial data line between the plug-in position holding the respective receiver and transceiver card and a respective one of the input ports of the central selection unit; and (e) wherein the central selection unit has an output port to which one of the high bit-rate data signals can be fed in a controllable way.
