Abstract:
1. A dispersion compensator, comprising: an input port for receiving a WDM optical signal; a dispersion compensating element coupled to the input port for substantially compensating the WDM optical signal for dispersion that has accumulated along an external transmission path; an output port for directing the dispersion compensated WDM optical signal to an external element; and a dynamic power controller for maintaining a total power of the WDM signal below a prescribed level prior to receipt of the WDM optical signal by the dispersion compensating element, wherein said prescribed level below which the total power of the WDM optical signal is to be maintained is sufficient to substantially avoid non-linear interactions in the dispersion compensating element, and said dynamic power controller determines the total number of channels and the total power in said WDM optical signal.
