Adaptive traffic-aware and energy-efficient ONU sleep mechanism for sustainable passive optical networks
Abstract For delivering the symmetrical upstream and downstream speeds over the existing fiber, 10 Gigabit symmetrical PON (XGS-PON) is a promising solution. In this paper, a traffic-aware energy-efficient XGS-PON system employing adaptive ONU operating states is proposed and analyzed. The system operates at 10 Gbps in...
