Next generation hworigh-speed optical netks for metro access

互联互通是现代“信息社会”的主动力，数据驱动的应用呈现爆炸式增长，新型信息化价值链快速形成。光网络是全球通信基础设施的支柱，连接着数十亿人和大量各种自主设备、控制系统和机器。在超高清流媒体、云服务、5G扩散等基于网络的服务的推动下，光学系统的发展刺激了数据交换和利用需求的急剧增长，促进了数字世界的变化，并塑造了现代社会的结构。接入和城域链路的需求增长尤其明显，这些链路将需要大大超过当前< 1tb /s的数据速率。此外，随着大量人员在家办公，新冠肺炎疫情加剧了光纤网络的压力。此外，诸如系统元素的财务成本、延迟、动态可重构性和能耗等特性对于新一代接入网和城域网越来越重要。博士网络NESTOR将回答如何？什么时候?和在哪里?相干光收发器将被部署在城域聚合光网络中，以满足新的成本效益解决方案的需求。NESTOR还将解决Who？通过为10名新一代工程师研究员提供高级培训，大大扩展了接入网/城域网的灵活性和容量。NESTOR利用顶级学术团体（Aston、PoliTO、UPC、SSSA和TU/e）和核心电信行业（Infinera、BT、Orange、SM-Optics、VPI和爱立信）的互补专业知识。NESTOR将为研究员提供独特的广泛教育，从ML&AI的最新进展到现实世界的电信工程，这将使他们能够设计和实施高容量接入和城域网络。

Connectivity is the major driver in the modern "information society", where the range of data-driven applications is exploding, and new information-based value chains are rapidly emerging. Optical networks are the backbone of the global communication infrastructure, interconnecting billions of people and a huge number of various autonomous devices, control systems, and machines. Optical systems' development incites the skyrocketing growth in the demand for data exchange and harnessing, fuelled by web-based services such as ultra-HD streaming, cloud services, 5G proliferation, fostering the changes in the digital world, and shaping the structure of the modern society. The demand growth is especially pronounced in the access and metro links, where data rates largely exceeding the current <1 Tb/s will be required. Moreover, the COVID-19 - with the huge number of people working from home - has intensified the pressure on the optical networks. Also, features such as the financial cost of the system elements, latency, dynamic reconfigurability, and energy consumption gain progressively more importance for the new generation of access and metro networks.The Doctorate Network NESTOR will answer the How? When? and Where? coherent optical transceiver will be deployed in metro-aggregation optical networks to meet the demand for new cost-efficient solutions. NESTOR will also address the Who? by providing advanced training to 10 Fellows - from a new generation of engineers - with PhD projects significantly expanding the flexibility and capacity of access/metro networks. NESTOR harnesses the complementary expertise of the top academic groups (Aston, PoliTO, UPC, SSSA, and TU/e) and core telecom industry (Infinera, BT, Orange, SM-Optics, VPI and Ericsson). NESTOR will provide Fellows with a uniquely broad education ranging from recent advances in ML&AI to real-world telecom engineering, which will enable them to design and implement high-capacity access and metro networks.
