ABSTRACT:
A Wavelength Division Multiplexing (WDM) optical monitor, based on concatenated fiber gratings, uses a single modulator and detector and has high dynamic range and good sensitivity through signal averaging. The WDM optical monitor may be implemented in a time-domain or frequency-domain embodiment and used for SNR measurement of WDM optical signals.
