Energy consumption of Next-Generation PONs is estimated in a major
IntroductionTelecom market competition and an increasing demand for content-rich services such as High Definition (HD) and 3D video are driving the evolution to high speed access. At the same time, network energy consumption and its associated cost are an increasing concern for telecom operators [1]. In this paper, we evaluate the energy demand of high speed connectivity services offering up to 1 Gb/s to each customer in Fiber To The Premises (FTTP) Next-Generation Passive Optical Networks (NG-PON). A major European city is used as deployment scenario for power consumption evaluation. The paper is organized as follows; first, the deployment scenario, PON technologies and connectivity service model are described; next, the methodology for energy consumption analysis is reported; finally, results of energy evaluation and the main conclusions are provided.
