Break-Out Sessions
Break -out Sessions Abstracts APPLICATIONS HALL Applications Software Group Portfolio Enterprises and carriers have similar software needs. Enterprises seek software applications that help them provide innovative service to their customers. Carriers seek software applications that help them create innovative, profitable products to sell to consumers. In both cases, the service or product must be delivered across multiple devices and channels. This session will highlight the Application Software Group portfolio positioning, the benefits for customers looking at portfolio solutions and also highlight a few cross portfolio use cases such as Customer Experience Management. Jessica Stanley-Yurkovic, Vice-President, North American Marketing Maximize Customer Experience and Accelerate Business Transactions Using Open APIs End users expect the type of rapid application innovation known from the Internet. Leading network services providers have recognized that they need to work together with innovative third party application developers and create a win-win situation for both parties. The key to this is application enablement. By utilizing network assets, developers can create a more seamless service experience for end users and can help businesses close transactions with their customers more effectively. This session will describe the open API program of the Alcatel-Lucent Application Software Group. The program is designed to help our customers turn their network assets into valuable enablers for maximizing the end-user experience.

Study and analysis of future trends in the generation of Ten-Gigabit-Capable Passive Optical development of next-generation fixed broadband optical Networks (XG-PON1) has been published in 2010 by ITU-T network is performed. The main intention of this paper is to [4]. This standard will offer 10 Gbit/s downstream and 2.5 describe migration from Gigabit-capable Passive Optical Gbit/s upstream speed; but, target distance and split ratio did Network (GPON) to Ten-Gigabit-Capable Passive Optical not increase much. Research in this area continues the job to Networks (XG-PON). Paper answers the question of what bring even better P2MP technology. Most of them are today extent active and passive GPON elements need to be replaced known under the term second generation of next-generation and what needs to be added when migrating to XG-PON. -

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. -

Wired, Optical, and Wireless Communications Book
Wired, Optical, and Wireless Communications Book Outside Plant Chapter What is the Outside Plant The first topic to consider is what is the outside plant? In general outside plant connections are those exterior to a building. Typically these are used to connect one building to another. This type of connection can be completed using wired media or a wireless connection. Standards and Codes Adherence to applicable standards and codes is required for any network construction project. A standard is used to provide guidelines for the type of material to use, as well as suggested installation practices. Notice that a standard is not a requirement. A standard is designed to achieve a basic level of performance. While it is true that many extant networks function without applying these standards, eventually they are overwhelmed by errors when the load on the network increases to a level such an ad hoc network cannot sustain. Troubleshooting is then very difficult. Time is wasted attempting to determine how the network was constructed. Codes were created to protect lives and property. Ignoring codes leads to legal liability at the least. Often work must be redone when an inspection reveals lack of compliance. A code is a requirement. The authority having jurisdiction or AHJ decides what codes to require. In most cases this will be a city government. Some areas, such as rural areas, may not have as many codes in their jurisdiction. Nevertheless, the commonly adopted codes should be adhered to, even if they are not required. An outside plant installation must be done following the applicable codes and standards in case of an accident or dispute. -

Understanding FTTH Architecture TOPOLOGY and COMPONENTS
Understanding FTTH Architecture TOPOLOGY AND COMPONENTS TODD M. CORCORAN, RTPM, CFHP TECHNICAL PROGRAM MANAGER Q: What is meant by a Central Office or a Hut? A: The location where all major electronics for the system are housed for a given town. Q: What is topology? A: In a FTTH system, the word “topology” in is most often used with the physical fiber plant or Outside Plant (OSP). Q: What is splice closure or case? A: A fiber management product that protects and houses optical splices. Q: What is a PON? A: A PassiveUnderstanding Optical Network that distributes an optical signal from the CO to the customer. Q: What is Active Ethernet? A: A techniqueGeneral that uses Ethernet Terms (a data communications protocol) as the main transmission method over fiber optics with data rates up to 1 Gb/s. Q: What is meant by G-PON? A: Gigabit PON is a system that handles data rates up to 2.5 Gb/s. Q: What is meant by an OLT, ONT, and splitter? A: OLT - Optical Line Terminal, located in the CO or hut, is the interface to the customer and provides the subscribed services. ONT – Optical Line Terminal, located at the customer/subscribers location, converts the optical media being sent by the OLT. Splitter - A passive device that splits the light source in separate paths. Splice Fiber Cables for FTTx Closure Drop ONT • Single-mode fiber (SMF) is used in a FTTx application • Optical fiber is the transmission component of the ODN Feeder Cables – These cables are the main cable(s) being routed through a populated area.
