Abstract
A method for determining optical power in a WDM optical signal that includes extracting a representative portion of the optical signal with wavelengths within some band δ wherein δ is a subset of Δ, the set of all channel wavelengths present in the optical signal and measuring the intensity of the extracted optical signal to determine the optical power per channel for any of the channels whose wavelengths are within the band δ.
