PROBLEM TO BE SOLVED: To provide a device for a synchronization of data in an optical WDM transmission system. SOLUTION: The device for a synchronization of data in an optical WDM transmission system comprises a wavelength demultiplexer 1 for demultiplexing the incoming data stream in the synchronizer, delay lines 2 for the individual wavelength channels, a multiplexer 10, a modulator 3 using a high-frequency clock signal 5, and at least one photodetector 4 tapped to output line B, where the photodetector 4 is connected to an electronic control circuit 6 which is connected to the individual delay lines 2 for automatic adaptation. |
