Deploying 10 Gigabit Access Networks DEPLOYING 10 GIGABIT ACCESS NETWORKS Using the Emerging NG-PON2 and XGS-PON Standards Solution Overview UNDERSTANDING NG-PON2 ARCHITECTURE Converging Multiple Services This flexible optics approach allows for mass market 10/10G NG-PON2/XGS-PON adoption for all broad- over a Common Access band applications (Figure A) while maintaining flexibility Services Architecture for the future overlay of an additional fixed optics 10/10G The primary value of NG-PON2 is the ability to serve business PON and/or multiple TDWM PONs using a mix of residential, business and backhaul services higher capability tunable optics (Figure B). over a common Optical Distribution Network (ODN) The ADTRAN NG-PON2 system elegance offers the using a mix of point-to-point and point-to-multipoint ability to benefit from mass market price points without technologies. The biggest challenge facing NG-PON2 having to wait for large volumes to be reached in the is coming up with a single system that meets the scale 10G PON market. This approach gives service providers and flexibility needs of premium business and backhaul confidence that they can move forward with a 10G PON services while also delivering on the price points needed strategy today, without the risk of depending on a future for mass market residential applications. worldwide volume ramp of 10G and tunable optics to make it cost-effective. On the OLT side, any mix of optics can be used on a single OLT, allowing for maximum Flexible Optics Balance flexibility without compromising on future capabilities. Cost and Scale Leveraging the additional capacity available through the Realizing that the major cost component of any disruptive ADTRAN NG-PON2 solution set, service NG-PON2 system is the cost of the optical transceivers providers can extract an additional five to ten years of (both at the OLT and ONT), ADTRAN® has developed revenue from this year’s residential PON deployments, a flexible optics approach to NG-PON2 that allows for maximizing future service flexibility and minimizing risk a single NG-PON2 OLT system to utilize multiple types of subscriber churn. of optical transceivers, allowing the service provider to better align the cost with the target application. Solution Programmability and a The flexible optics range from low cost fixed optics for residential, business and small cell broadband Commitment to Open Interfaces applications to fully-tunable optics for premium Simplifies Converged Operations enterprise, datacenter, fronthaul and backhaul Additionally, the operational cost and complexity to services. Through further innovation in the ONT connect a FTTH subscriber can be further reduced to optics design, ADTRAN has developed a fixed accelerate the expansion of Gigabit broadband services. optics 10/10G ONT solution compliant to NG-PON2, ADTRAN’s solution supports provisioning through XGS-PON, and GPON standards that allows for the modern, open APIs, facilitating the deployment in immediate support of NG-PON2 ONTs for business next-generation SDN-based management systems. and backhaul services as well as being able to seed Both the ADTRAN OLT and ONTs support open, the residential market with less complex NG-PON2 standard-based, physical interfaces allowing for the ONTs nearing the price level of today’s mainstream support of best-in-breed network design and the GPON ONTs. delivery of universal CPE across a multi-vendor network. This in concert with accelerated mass market electronics and optics pricing ensures that cost-sensitive residential broadband will be viable using NG-PON2/ XGS-PON technology. XGS-PON is a fast developing standard supported by the leading service providers and vendors around the world for 10 Gbps (XG) Symmetric fixed wavelength PON over the already established GPON/NG-PON2 infrastructure.

  • Evolution of Access Network Sharing and Its Role in 5G Networks
    applied sciences Review Evolution of Access Network Sharing and Its Role in 5G Networks Nima Afraz * , Frank Slyne , Harleen Gill and Marco Ruffini * CONNECT Centre, Trinity College, The University of Dublin, 2 Dublin, Ireland; [email protected] (F.S.); [email protected] (H.G.) * Correspondence: [email protected] (N.A.); marco.ruffi[email protected] (M.R.) Received: 3 October 2019; Accepted: 18 October 2019; Published: 28 October 2019 Abstract: This paper details the evolution of access network sharing models from legacy DSL to the most recent fibre-based technology and the main challenges faced from technical and business perspectives. We first give an overview of existing access sharing models, that span physical local loop unbundling and virtual unbundled local access. We then describe different types of optical access technologies and highlight how they support network sharing. Next, we examine how the concept of SDN and network virtualization has been pivotal in enabling the idea of “true multi-tenancy”, through the use of programmability, flexible architecture and resource isolation. We give examples of recent developments of cloud central office and OLT virtualization. Finally, we provide an insight into the role that novel business models, such as blockchain and smart contract technology, could play in 5G networks. We discuss how these might evolve, to provide flexibility and dynamic operations that are needed in the data and control planes. Keywords: access networks; network sharing; 5G networks; multi tenancy; optical access; sharing economics 1. Introduction By its nature, a telecommunications network is a shared resource that interconnects multiple nodes. Network sharing is part of a fundamental principle of statistical multiplexing of link capacity.

  • Beyond LTE: Enabling the Mobile Broadband Explosion
    Beyond LTE: Enabling the Mobile Broadband Explosion August 2014 Key Conclusions (1) • Mobile broadband—encompassing networks, devices, and applications—is becoming one of the most successful and fastest-growing industries of all time. • Computing itself is transitioning from a PC era to a mobile era. Many users will never interact with a PC. • Consumer and business applications have until now driven data demand, but machine-to-machine communication, also called Internet of Things, will generate progressively higher volumes of traffic in the future. • Cloud computing is a significant and growing contributor to data demand. Growth drivers include cloud-based data synchronization, backup, applications, and streaming media. • The wireless industry is addressing exploding data demand through a combination of spectrally more efficient technology, denser deployments, small cells, HetNets, self-configuration, self-optimization, use of unlicensed spectrum with Wi-Fi, and the future possibility of LTE operation in unlicensed bands. • Initial LTE deployments have been faster than any wireless technology previously deployed. Beyond LTE: Enabling the Mobile Broadband Explosion 2 Rysavy Research, 2014 White Paper Key Conclusions (2) • LTE has become the global cellular-technology platform of choice for both Global System for Mobile Communication (GSM)-UMTS and Code Division Multiple Access (CDMA)/Evolution Data Optimized (EV-DO) operators. Worldwide Interoperability for Microwave Access (WiMAX) operators are adopting LTE-Time Division Duplex (LTE-TDD). • The wireless technology roadmap now extends through International Mobile Telecommunications (IMT)-Advanced, with LTE-Advanced defined to meet IMT- Advanced requirements. LTE-Advanced is capable of peak theoretical throughput rates exceeding 1 gigabit per second (Gbps). Operators began deploying LTE-Advanced in 2013.
