ABSTRACT:
A Wavelength-Division-Multiplexed (WDM) network provides delivery of both switched services and broadcast analog video over optical facilities through an intermediate optical apparatus (e.g., Passive Optical Network (PON)) splitter to a plurality of remote optical apparatuses (e.g., optical-network units (ONUs)). The broadcast signal is provided to only a selected ONU, together with the switched service signal for that selected ONU, the selected ONU then distributes the broadcast signal to other ONUs over a separate distribution facility interconnecting the ONUs.
