Abstract
An add-drop multiplexer has a group filter that divides an incoming WDM signal into several channel groups of corresponding adjacent WDM channels. A reconfiguration module is connected to each channel group. A first type of module makes it possible to perform a manual configuration of the Add-Drop channels and the coupled WDM channel while a second type of module makes it possible to carry out remote configuration. A fourth type of module enables remote configuration of the drop-continue channels.
