Zusammenfassung:A device and method for optical power measurement in an optical network supporting upstream and downstream signal propagation along an optical transmission path. An upstream wavelength analyzer receives upstream light extracted from the optical transmission path and is configured to determine an upstream spectral characteristic of the extracted upstream light. A downstream optical power meter assembly receives downstream light extracted from the optical transmission path and is configured to measure an optical power parameter of a downstream signal. A processing unit is configured to determine, based on the upstream spectral characteristic, at least one pass/fail threshold associated with the measured optical power parameter of the downstream signal.
