“…As the NGOA candidate, different system concepts are actively considered such as: high data rate time division multiple access (TDMA) passive optical network (PON) such as 40G-TDMA-PON, wavelength division multiplexing (WDM) PON, hybrid TDMA/WDM PON (TWDM-PON), point-to-point (PtP) and active optical network (AON) [6]. We will also compare these NGOA solutions with present state-of-art solutions like Ethernet PON (EPON) and 10G-EPON (10G-EPON).…”

Abstract: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 power shedding, doze and sleep.

“…1, we present the PC model of the ONU. The model takes data from [5][6][7][8][9][10] and the large survey of component datasheets. To compare the technologies fairly, the power consumption data of components are scaled relative to the power consumption value of 1.2 W of the GPON TRX as adopted in [7].…”

“…Estimations of energy consumption of NG-PON(2) technologies have already been reported, providing the total energy consumption per customer considering both network operator and customer premises contributions [2,3]. Some proposals have recently shown the potential for reduction of the energy consumption in customer premises equipment (CPE), for example using a bit-interleaving protocol at the optical networking unit (ONU) in time-division multiplexing PONs [4] or a networkenhanced residential gateway approach [5].…”

Energy efficiency analysis of high speed triple-play services in next-generation PON deployments

et al. 2015

In this paper, the energy consumption of high speed access services up to 1 Gb/s per customer is estimated for different passive optical network (PON) technologies. While other studies on PON power consumption typically assume a fixed split ratio, we also consider a greenfield approach, where the split ratio can be optimized for each technology, taking full advantage of its capacity and reach. The split ratio optimization takes into account Quality of Service (QoS) in terms of bandwidth availability and packet loss for triple-play services (voice, television and Internet). This paper includes an in-depth discussion of our split ratio dimensioning approach and our power consumption model for an optical access network in a major city. The obtained results show that statistical gain provided by dynamic bandwidth allocation as well as power splitting ratio optimization in PONs are key factors for achieving energy efficiency. For access rates up to 900 Mb/s, XG-PON1 turns out to be the most energy efficient option. For higher access rates up to 1 Gb/s, the optimal technology depends on split ratio restrictions. If an existing optical distribution network (ODN) with split ratio 1:64 is used, XG-PON1 remains the most energy efficient technology. If higher split ratios up to 1:256 can be achieved, TWDM PON becomes the most energy efficient solution for access rates up to 1 Gb/s.

“…The power consumption of the TEC in the OLT scales with the average heat load that has to be carried away, even though it does not follow the same on-off sleep cycles. There are WDM-PON variants with a seeded wavelength and reflective semiconductor optical amplifier RSOA instead of a tunable laser in the ONU (e.g., [5]), for which similar sleep mode concepts can be applied.…”
