Network virtualization technology such as cloud edges (CEs) will contribute to the cost-effective construction of carrier networks while maintaining saving of hardware and bandwidth resources. In this letter, we propose a future metro network architecture based on Next-Generation Passive Optical Network Stage 2 technologies to support CEs. This makes it possible to reduce the number of transmitters and receivers for the accommodation of both user traffic and traffic between CEs cost-effectively by sharing burst-mode transmitters and burst-mode receivers between CEs. We execute the preliminary evaluation of network capital expenditure with the proposed method by numerical simulation.
