Abstract
An apparatus for selectively adjusting power levels of component signals of a wavelength division multiplexed signal. The apparatus comprises a first filter and a second filter. The first filter modulates the component signals according to a static attenuation profile, thereby providing coarsely modulated component signals. The second filter is coupled to the first filter to receive the coarsely modulated component signals and to modulate the coarsely modulated component signals according to a dynamic attenuation profile, thereby providing finely modulated component signals.
