Next generation hworigh-speed optical netks for metro access

互联互通是现代信息社会的主要驱动力，数据驱动的应用范围正在爆炸式增长，基于信息的新价值链正在迅速涌现。光网络是全球通信基础设施的主干，连接着数十亿人和大量的各种自主设备、控制系统和机器。光学系统的发展刺激了数据交换和利用需求的飞速增长，这得益于基于网络的服务，如超高清流媒体、云服务、5G扩散，促进了数字世界的变化，并塑造了现代社会的结构。需求的增长在接入和城域链路方面尤为明显，这些领域的数据速率将大大超过目前的1TB/S。此外，由于大量的人在家里工作，新冠肺炎加大了光网络的压力。此外，系统元素的财务成本、延迟、动态可重构性和能源消耗等特性对新一代接入网络和城域网络越来越重要。什么时候?在哪里呢？将在城域汇聚光网络中部署相干光收发器，以满足对新的低成本解决方案的需求。内斯特也将向谁发表讲话？通过向10名研究员(来自新一代工程师)提供高级培训，博士项目显著扩展了接入/城域网络的灵活性和容量。Nestor利用顶尖学术团体(Aston、Polito、UPC、SSSA和TU/e)和核心电信行业(英飞朗、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和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大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.
