<p>The add-drop multiplexer has a group filter (1) that divides an incoming WDM signal (WMS1) into several channel groups (G1 to G4) of corresponding adjacent WDM channels (K1 to K8, ...). A reconfiguration module (M1-M4) is fed to each channel group. A first type of module (MM) makes it possible to perform manual configuration of the Add-Drop channels and the coupled WDM channels (K1-K8, ...) while a second type of module (MF) makes it possible to carry out remote configuration. A fourth type of module (MF25, MF26, MF27) enables remote configuration of the drop-continue channels (K25-K32).</p> |
