Flexible TDMA/WDMA passive optical network: Energy efficient next-generation optical access solution
Access networks must further advance to address the intensification of the requirements of growing speeds and the usage of Internet applications, and time and wavelength division multiple access (TDMA/WDMA) based passive optical networks (TWDM-PONs) have been widely considered as one of the evolutionary steps of next-generation optical access (NGOA) networks. TWDM-PON combines the flexibility o...
متن کاملEnabling next Generation Ethernet Access with Ethernet Passive Optical Networks
This article describes Ethernet Passive Optical Networks (EPONs), an emerging local subscriber access architecture that combines low cost point-to-multipoint fiber infrastructure with Ethernet. EPONs are designed to carry Ethernet frames at standard Ethernet rates. EPONs use a single trunk fiber that extends from a central office to a passive optical splitter, which then fans out to multiple op...
متن کاملEnergy Efficient Ethernet Passive Optical Networks (EPONs) in Access Networks
As concerns about energy consumption grow, the power consumption of the EPON becomes a matter of increasing importance in the heterogeneous networks. In respect of energy efficiency, the current standard has no management protocols aiming to reduce power consumption in EPONs. To increase energy efficiency while satisfying diverse QoS requirements, the sleep mode operation is introduced in an Op...
متن کاملEnergy Efficiency in Passive Optical
This article provides an overview of current efforts in reducing energy consumption in passive optical access networks. Both ITU-T and IEEE standardized PONs are considered. The current solutions proposed by standardization authorities, industry, and academia are classified based on the layer they address in the standardized architectures: physical layer, data link layer, and hybrid. Then, the ...
متن کاملONU power saving modes in next generation optical access networks: progress, efficiency and challenges.
The optical network unit (ONU), installed at a customer's premises, accounts for about 60% of power in current fiber-to-the-home (FTTH) networks. We propose a power consumption model for the ONU and evaluate the ONU power consumption in various next generation optical access (NGOA) architectures. Further, we study the impact of the power savings of the ONU in various low power modes such as pow...
