“…In the last few years, several approaches have been defined to deploy next generation access (NGA) networks. Various Fiber To The X (FTTX) solutions differ for the different fiber termination point in the optical distribution network (ODN), e.g., the local exchange in Fiber To The Cabinet (FTTC) solutions, or the boundary of living spaces in Fiber To The Home (FTTH) solutions [2].…”

In the very last years, optical access networks are growing very rapidly, from both the network operators and the research interests points of view. Fiber To The Home (FTTH) is already a reality in plenty of real contexts and there has been a further stimulus to the proposal of new solutions and the investigation of new possibilities, in order to optimize network performance and reduce capital and operational expenditure. A complete and systematic overview of passive optical access networks is presented in this paper, concerning both the hot research topics and the main operative issues about the design guidelines and the deployment of Passive Optical Networks (PON) architectures, nowadays the most commonly implemented approach to realize optical fiber links in the access networks. A comparison of advantages and disadvantages of different multiplexing techniques is discussed, with specific reference to WDM-based networks, almost universally considered as the enabling technology for future proof bandwidth requirements. An exhaustive summary is also given about the-state-of-the-art of modulation and encoding techniques recently proposed by the scientific community, as well as the open challenges (such as colorless and coolerless ONUs) for telecom companies and international standardization compliance.

“…Consequently, the goal of many telecom operators around the world is to balance short-term investments and long-term goals 6 , evaluating all the technical–economic aspects to determine what the benefits and disadvantages of both technologies and infrastructure management approaches are 7 – 9 . Developing an infrastructure from scratch and evaluating all management and maintenance aspects requires enormous capital and operational investments 10 .…”

Telecommunications companies are constantly chasing continuous technological advances with their management methods of Operations & Maintenance (O&M) that still struggle to turn their eye toward innovation and simplification of processes. In a future that aims at fully fiber-optic networks, the objective of the research is to propose guidelines and provide data to support the Wholesale Operator for the definition of the acceptable attenuation threshold on the Passive Optical Network Fiber-To-The-Home (PON FTTH) infrastructure to determine the Service Level Agreements (SLA) to be contracted with Retail Operators. Following exceeding the threshold, the Retail Operator has the right to open a Trouble Ticket to request the resolution of the anomaly. Consequently, the definition of the attenuation threshold strongly affects the number of Trouble Tickets to be managed and the related costs the Wholesale Operator bears. This paper analyzes a specific case of the PON FTTH network of the Italian wholesale operator Open Fiber. The studied infrastructure, with a length of 11 km, allows a maximum attenuation of 37 dB without degrading the service. An economic model has been proposed to assess the cost impact of moving the attenuation threshold in the SLA.

“…See for example, Oxera (2011) andKatsianis et al (2012). 8 This is also true on the wholesale market: a conventional BU LRIC þ cost-oriented linear wholesale access price applied to NGA infrastructure with low penetration rates would lead to prohibitively high values, which are incompatible with adoption by any customer.L.…”

Economic replicability tests for next-generation access networks

a b s t r a c tThis paper discusses the relevant cost standard for the economic replicability test for NextGeneration Access (NGA) networks, described in the "Recommendation on consistent nondiscrimination obligations and costing methodologies" adopted by the European Commission. According to the Recommendation, in order to reconcile investment and competition, wholesale prices should have nonlinear characteristics and only partly vary by the number of accesses. It demonstrates that a cost standard for the economic replicability test, which implies fully fixed and variable cost recovery for the access seeker, including the total wholesale price, would be incompatible with the economics of NGA networks and that such a test would deter NGA investment. Therefore, the cost standard should include only the variable part of the wholesale price. However, this paper underlines that during a transition phase, until competitors have secured access to NGA infrastructure, a second temporary test called the "competition migration test" should be added to ensure incumbent NGA retail prices do not foreclose efficient copper-based entrants. The two proposed tests surpass the limits of the "ladder of investment" theory by including the "business migration effect" developed by Bourreau, Cambini, and Dogan (2012).
