Next-generation optical access networks should not only increase capacity but also be able to redistribute capacity on the fly in order to manage larger variations in traffic patterns. Wavelength reconfigurability is an instrument that can enable such capability of network-wide bandwidth redistribution since it allows dynamic sharing of both wavelengths and timeslots in WDM-TDM optical access networks...
We propose a cost-effective, reconfigurable optical access network by employing passive components in the remote node and dual conventional optical transceivers in ONUs. The architecture is demonstrated with bidirectional transmission at 10 Gb/s.
