“…Next-generation PON technologies are considered, including 10 Gb/s PON (XG-PON1 E2 class) as well as several candidates of the second generation systems (NG-PON2) with at least 40 Gb/s capacity per PON. The technological framework of NG-PON2 systems has been described by the FSAN (Full Services Access Network) group [1]. In this paper, we focus on the following NG-PON2 technologies:…”

“…Deployments of 2.5 Gb/s capable PONs (Gigabitcapable PON or GPON) are currently the most common, while 10 Gb/s capable PONs (next-generation PON or NG-PON) are expected in the next couple of years. In the long term, increasing bandwidth demands associated with mobile backhauling, low-latency cloud services and the convergence of residential and business access will necessitate the deployment of even faster next-generation PONs beyond 10 Gb/s, referred to as NGPON2s by the Telecommunication Standardization Sector of the International Telecommunication Union (ITU-T) and Full Service Access Network (FSAN) Group [1].…”

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

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.

“…A highly-branched fibre optic access network such as LR-PON can serve big areas with very large (and diverse) number of users. It is therefore crucial to offer a flexible level of resilience able to satisfy the required Service Level Agreements (SLAs) of mobile backhaul systems, business customers and critical services requiring non-interrupted network access [7]. In this context, there are two main challenges associated with providing protection in LR-PON, namely deployment cost and flexibility of upgrading the infrastructure.…”

Fibre-to-the-premises (FTTP) has promised to increase the capacity in telecommunications access networks for well over thirty years. While it is widely recognized that optical fibre based access networks will be a necessity in the short to medium term future, its large upfront cost and regulatory issues are pushing many operators to further postpone its deployment, while installing intermediate, unambitious solutions such as Fibre-to-the-cabinet (FTTC). Such high investment cost of both network access and core capacity upgrade often derives from poor planning strategies that do not consider the necessity to adequately modify the network architecture to fully exploit the cost benefit that a fibrecentric solution can bring.DISCUS is a European Framework 7 Integrated Project that, building on optical-centric solutions such as Long-reach passive optical access and flat optical core, aims to deliver a cost-effective architecture for ubiquitous broadband services. DISCUS analyses, designs and demonstrates end-toend architectures and technologies capable of saving cost and energy by reducing the number of electronic terminations in the network, and sharing the deployment costs among a larger number of users, compared to current fibre access systems. This paper describes the network architecture and the supporting technologies behind DISCUS, giving an overview of the concepts and methodologies that will be used to deliver our end-to-end network solution.

“…Optical access networks are the most innovative way to improve network performance and effectively meet subscribers' demands for high-quality broadband service. Several access network structures possessing the advantages of cost efficiency, high-speed transmission, large capacity, long-reach and large separation rates [1], high resource efficiency [2], strong survivability, and energy efficiency [3] have been proposed. Passive optical networks (PONs) have been widely deployed as flexible, scalable optical access networks in recent years.…”

We demonstrate an optical asynchronous transfer mode/wavelength division multiplexing (OATM/WDM) optical access network, using a router based on an optical header decoder to conduct next-generation communications. The router consists of a decoder or hardware analysis processing of the header bit and switches. The router in the OATM/WDM optical access network is a key technology by which to satisfy subscribers' requests, including reliability, cost efficiency, high speed, large-capacity transmission, and elevated information security. In this study, we carry out experiments in which a header decoder delivers to 16 and 32 subscribers with a single wavelength in the router. These experiments confirm the decoder's successful operation via hardware using 4 and 5 header bits. We propose that this system may significantly contribute toward the realization of an optical access network that provides high-quality service to subscribers of next-generation communications.
