A distribution node for an optical network is provided that includes an
integrated filter module comprising a first thin-film and a second
thin-film coupled to a common substrate and operable to receive a first
downstream signal at the substrate comprising at least traffic in a first
wavelength and a second wavelength, transmit the traffic in the first
wavelength from the first thin-film to a first plurality of downstream
terminals, reflect the traffic in the second wavelength to the second
thin-film, and transmit at least the traffic in the second wavelength
from the second thin-film to a second plurality of downstream terminals.
A traffic distributor is operable to receive a second downstream signal
comprising at least traffic in a third wavelength and forward the traffic
in the third wavelength to the common substrate for distribution to the
first plurality and second plurality of downstream terminals.
