Claim Text:
1. A computer-implemented method of indicating channel health in a wavelength division multiplexing system, the method comprising: determining, by one or more computing devices, an optical signal to noise ratio (OSNR) of a channel of the wavelength division multiplexing system; comparing, by the one or more computing devices, the OSNR of the channel to one or more OSNR thresholds to determine an OSNR health of the channel; determining, by the one or more computing devices, a channel power minus a frequency shift loss of the channel; comparing, by the one or more computing devices, the channel power minus the frequency shift loss to one or more power thresholds to determine a power health of the channel; determining, by the one or more computing devices, a center frequency shift of the channel; comparing, by the one or more computing devices, the center frequency shift of the channel to one or more frequency thresholds to determine a frequency health of the channel; determining, by the one or more computing devices, a health of the channel based at least in part on the OSNR health, the power health, and the frequency health, the health of the channel being a single indication of the overall healthiness of the channel; and displaying, by the one or more computing devices, the health of the channel on a display device.
