An optical architecture is provided comprising at least one broadband
light source, a mod/mux unit, and a plurality of premises stations in
communication with the mod/mux unit via an optical distribution hub. The
mod/mux unit is configured to permit selective modulation of
demultiplexed components of a target wavelength band of an optical
signal, multiplex the selectively modulated optical signal, and direct
the target wavelength band and a bypass wavelength band of the
multiplexed optical signal to the optical distribution hub. The optical
distribution hub comprises an arrayed waveguide grating configured to
demultiplex the multiplexed optical signal and distribute respective
distinct wavelength portions of the target wavelength band and respective
distinct wavelength portions of the bypass wavelength band to respective
ones of the premises stations.
