Passive optical access networks have been adopted to solve bandwidth bottle-neck in the last mile. In this paper, we propose a solution to improve their power efficiency and reliability by dual-homing in GPON and XG-PON coexistence. The dual-homing ONU, which have both GPON and XG-PON functionality, is proposed in order to be able to communicate with both GPON and XG-PON OLT. During light-load hours, the ONU can switch from XG-PON mode to GPON mode to save the power consumption. Our analysis shows that the scheme can potentially save up to 31.8% for the overall network consumption.
