Abstract
A method of monitoring a WDM optical signal is provided. The method includes: receiving a WDM optical signal having a plurality of channels; detecting the optical signal after filtering the WDM optical signal with a tunable filter; and reconfiguring at least the center wavelength and bandwidth of the tunable filter optical transfer function to determine a signal performance parameter of the WDM optical signal.
