Description: This paper proposes a power efficient optical access network architecture that reduces OLT power consumption. Several PON trees are aggregated thanks to waveguide optical
switches with nano second-order switching speed. The proposed network dynamically activates/deactivates OLT according to ONU
traffic load, and reduces OLT power use while maintaining transmission fairness.
