We have proposed and demonstrated a new optical monitoring technique based on scanning the gain (or loss) profiles of the erbium-doped fiber amplifiers for WDM networks. The maximum measured error of 6 0.31 dB, the sensitivity of À50 dBm, and the dynamic range of 34 dB have been achieved experimenta
