ABSTRACT:
The invention relates to a data transmission unit for high bit-rate optical data signals, in particular, high bit-rate optical data signals with a backplane, which has a line structure connecting several plug-in positions for several receiver or transceiver cards to each other and/or to one or more additional data processing cards, with the cards, each held in one of the plug-in positions and each having at least one input port for a high bit-rate data signal. Each card also has at least one output port, to which the relevant one or more high bit-rate data signals can be fed, and each of these output ports is connected via a serial data line between the plug-in position holding the relevant receiver or transceiver card and an input port of a central selection unit with the relevant input port. The output ports connect serially to the central selection unit.
