Abstract: PROBLEM TO BE SOLVED: To provide an optical signal power control method at add/drop nodes in WDM (wavelength division multiplex) optical communication system. SOLUTION: The level of optical signal power of selected optical channel processed in an add/drop node of a WDM system is adjusted as a function of signal power fluctuation of incoming WDM signals generated by gain ripple. In particular, a ripple fitting method is described. According to this method, optical signal power of each optical channel added by the add/drop node is adjusted to a level corresponding to a ripple profile of another optical channel routed through the add/drop node. According to this arrangement, gain ripple of a WDM signal outputted from the add/drop node is made to correspond almost to the gain ripple of a WDM signal arriving to the add/drop node.

Abstract: Optical signal power levels for selected optical channels processed within an add/drop node in a wavelength division multiplexed (WDM) system are adjusted as a function of variations in signal power in an incoming WDM signal caused by gain ripple. In particular, a "ripple fitting" method is described whereby the optical signal power of individual optical channels being added at the add/drop node are adjusted to levels that correspond to the ripple profile of other optical channels being routed through the add/drop node. In this manner, the gain ripple in the WDM signal being output from the add/drop node approximately corresponds to the gain ripple i n the incoming WDM signal at the node.
