Data transmission unit for high-bit-rate data signals, in particular high-bit-rate optical data signals is greater than 1 gbit / s

摘要

The invention relates to a data transmission unit for high-bit-rate optical data signals, in particular hochbitrantige optical data signals, with a backplane (3), which a conductive structure having a plurality of (n) of plug-in slots (5, 7, 9) for a plurality of (m) receiver - or transceiver - cards (11, 13, 15) with one another and / or with one or more further data processing cards, with a plurality of receivers - or transceiver - cards (11, 13, 15), which, in a respective one of the plug-in locations (5, 7, 9) are received and which in each case at least one input port (11b, 13b, 15b) for each have a hochbitratiges data signal.According to the invention, each of the receivers - or transceiver - cards at least one output port, which the respective at least one high bit rate data signal can be supplied, and each of these output ports (5b, 7b, 9b) is connected over a serial data line (29, 31, 33) between which the relevant receiver - or transceiver - card (11, 13, 15) receiving slot (5, 7, 9) and an input port (23a) of a central selection unit (23) with the respective input port (23a) connected.Furthermore, each of these output ports, in each case via a serial data line between the the respective receiver - or transceiver - card receiving plug-in location with the respective input port, wherein the central selection unit (23) has an output port (23b), which can be controlled or one of the high bit-rate ..
