Method for adjusting time delays and device for synchronization of channels in a WDM system |
摘要 |
The invention is also related to devices for a synchronization of data in an optical WDM transmission system, consisting of the following parts: 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 ) modulated by 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 findividual delay lines ( 2 ) for an automatic delay control. |
