Abstract
In general, wavelength division multiplexed (WDM) communication systems may use wavelength selective switching to aggregate and/or deaggregate groups or bands of channel wavelengths. A wavelength selective switch (WSS) band aggregator may combine a plurality of channel band aggregate optical signals to produce a combined aggregate optical signal (i.e., a transmitted WDM or DWDM signal). The WSS band aggregator may also combine one or more spectral portions of broadband noise with the bands of channel wavelengths such that the spectral portion(s) of the broadband noise occupies unutilized channels in the combined aggregate optical signal. A WSS band deaggregator may separate a combined aggregate optical signal (i.e., a received WDM or DWDM signal) to produce a plurality of channel band aggregate optical signals.
