1. A fiber-optic communication apparatus comprising:
an optical monitor that monitors a wavelength division multiplexed (WDM) signal in which optical signals of multiple channels are multiplexed;
a processor that calculates a control value for controlling an optical power of the WDM signal, based on a power spectrum detected by the optical monitor, in a unit interval of frequency narrower than a channel bandwidth of the WDM signal; and
an optical power adjusting mechanism that adjusts the optical power of the WDM signal in the unit interval of frequency based on the control value.
