Abstract
Systems and methods are provided for optical channel monitoring (OCM) with an spectrally-multiplexed wavelength reference for monitoring of wavelength division multiplexing (WDM) spectrum.
Claims26
A system for processing optical signals, the system comprising:
- an optical channel monitor (OCM) processing block configured for optical channel monitoring, the processing block comprising:
- a wavelength reference (WLREF) circuit configured to generate a wavelength reference (WLREF) signal for use in wavelength calibration for optical channel monitoring;
- an optical channel monitor (OCM) circuit configured for monitoring WDM channels, the monitoring comprising measuring one or more characteristics associated with WDM signals communicated via the WDM channels;
- and
- a wavelength division multiplexing (WDM) combiner circuit configured to generate a combined signal based on combining of a first combining input signal and a second combining input signal;
- wherein the first combining input signal comprises an input WDM signal;
- wherein the second combining input signal comprises the WLREF signal or a signal generated based on the WLREF signal;
- and
- wherein the OCM circuit is configured to apply the monitoring to the combined signal.
