Abstract (en)

[origin: WO0057584A1] First, the wavelength multiplex (WDM) signal (S lambda 1-8) is partially compensated in a common dispersion compensator (DCF0). The partially compensated WDM signal is divided into individual partially compensated channel signals (ST1-ST8) in a wavelength demultiplexer (2). These are converted into electrical signals and compensated in filters (F1 to F8).
