The emergence of time and wavelength division multiplexed-passive optical network (TWDM-PON) architectures as next-generation access network technologies necessitates the development of new types of network devices and enhanced flexible operations. In this paper, we propose the software-defined (SD) energy-efficient architecture and operations in the TWDM-PON in which legacy PON devices are enriched with SD capabilities. The SD programmable operations deliver a balance between OLT and ONU energy-saving, while still guaranteeing the QoS requirements. We provide system performance and energy-savings trade-off analysis and compare the delay, throughput, and drop probability with the energy-savings performance in the OLT and ONU for various scenarios.
