Abstract:
1. An optical network for interconnecting a plurality of optical network units (ONUs) to an optical line terminal (OLT), in which the OLT comprises a plurality of OLT wavelength division multiplexed (WDM) optical transceivers connected to a plurality of feeder fibers through a wavelength sharing network, and each ONU comprises an ONU wavelength division multiplexed (WDM) transceiver, and in which a first of the said plurality of feeder fibers connects the wavelength sharing network to a first remote node that comprises a first WDM device that has a first plurality of output ports, a second of the said plurality of feeder fibers connects the wavelength sharing network to a second remote node that comprises a second WDM device that has a second plurality of output ports, at least one of the said first plurality of output ports is connected through a first drop fiber to an at least first ONU, at least one of the said second plurality of output ports is connected through a second drop fiber to an at least second ONU, and in which the wavelength sharing network comprises an optical combiner that allows the first and second ONUs share the same OLT WDM transceiver operating at the same wavelength.
