Abstract

An optical architecture is provided comprising a plurality of mod/mux units, a master optical distribution hub, a plurality of additional optical distribution hubs, and a plurality of premise stations. Each of the mod/mux units is configured to (i) permit selective modulation of demultiplexed components of a target wavelength band of an optical signal, (ii) multiplex the selectively modulated optical signal, and (iii) direct the multiplexed signal to the master optical distribution hub. The master optical distribution hub is configured to distribute multiplexed signals from respective ones of the mod/mux units to corresponding ones of the plurality of additional optical distribution hubs. Each of the plurality of additional optical distribution hubs comprises an arrayed waveguide grating configured to demultiplex the multiplexed optical signal and distribute respective distinct wavelength portions of the target wavelength band to respective ones of the premise stations.
