Converging optical access with energy management networks to provide bidirectional services

We propose a converged access network for servicing various applications in smart buildings and cities. The network convergence aims to share equipment and energy by transmitting bidirectional smart grid data over the fault monitoring channel in the passive optical network systems. The proposed scheme can successfully transfer 100 Mb/s smart meter data over the fault-monitoring channel. It can provide both energy-efficient real-time and non-real-time smart services and enhance channel fault monitoring simultaneously. Energy savings of up to 80% can be achieved for each ONU. The scheme successfully supported > 105 devices for smart meters data for each ONU.
