| 摘要 |
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.
