Abstract

In the past two decades, optical access networks have been widely deployed by operators around the world. The global optical access network market reaches about 1 billion users with a revenue of over 10 billion US dollars. As strategic tools to facilitate mass production, the optical access network standards play a crucial role in driving the product deployment and market growth. This paper overviews the latest effort in international standards bodies on the next generation optical access networks. It discusses projects in this area within the International Telecommunication Union’s Telecommunication Standardization Section (ITU-T), the IEEE, and the European Telecommunications Standards Institute (ETSI). Promising technologies are investigated with the goal of providing rates beyond 50 Gbps. Challenges are highlighted to satisfy the requirements on balancing access rates, loss budgets, and cost. Candidate systems are analyzed in three categories: point-to-multipoint (PtMP), point-to-point (PtP), and new applications. These standardization endeavors will jointly guarantee optical access networks as the premiere solution of wireline broadband access.

(ECOC 20 ) [特邀] 50G 之外是什么：光接入网络的未来标准

在过去二十年里，光接入网已被全球运营商广泛部署。全球光接入网市场约有 10 亿用户，收入超过 100 亿美元。作为促进大规模生产的战略工具，光接入网标准在推动产品部署和市场增长方面发挥着至关重要的作用。本文概述了国际标准机构在下一代光接入网方面所做的最新努力。它讨论了国际电信联盟电信标准化分会 (ITU-T)、电气和电子工程师学会 (IEEE) 和欧洲电信标准协会 (ETSI) 在这一领域的项目。对前景看好的技术进行了研究，目标是提供超过 50 Gbps 的速率。强调了满足平衡接入速率、损耗预算和成本的要求所面临的挑战。候选系统分为三类进行分析：点对多点 (PtMP)、点对点 (PtP) 和新应用。这些标准化工作将共同确保光接入网络成为有线宽带接入的首要解决方案。

期刊介绍： The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
