Towards Manufacturing of "Massive WDM" Metro (ToM3)

该制造合作的目的是解决城域网络下一代光通信系统的技术、架构、性能和制造需求。为了保证向终端用户提供高质量的服务，光城域网络在网络流量分布方面发生了前所未有的变化，导致了流量的集中和本地化，因此光城域网络正在经历巨大的增长。该计划针对两种特定的网络功能：紧凑、可扩展和节能的多载波“超级通道”收发器，波特率为28-32Gbaud及以上，以及可扩展的宽带（120nm）分段离散拉曼光纤放大器。将探索由数字相干技术和基于dsp的关键收发器参数监控实现的创新产品工艺，以解决阵列收发器的制造良率和延长测试时间。将开发新的设计，以最大限度地减少弯曲损失，人工干预，并利用机器人装配，从而在分段放大器制造的关键装配过程中引入所需的一致性。将探索新的设备架构和软件支持的重新利用，重点关注能源效率、成本效益、寿命和可制造性。系统性能将在服务于大伦敦等大城市的目标网络的详细数值模型中进行评估，并与在循环回路和扩展光纤试验台进行的大量实验室测试进行比较。

The aim of this manufacturing fellowship is to address the technology, architecture, performance and manufacturing needs of next generation optical communications systems for metro networks. Optical metro networks are undergoing tremendous growth as an unprecedented change in the distribution of network traffic, driven by requirements to ensure a superior quality of service to the end-user, leads to the concentration and localisation of traffic.The programme targets two specific network functions: compact, scalable and power-efficient multi-carrier "super-channel" transceivers at baud rates of 28-32Gbaud and above, and scalable, wide-band (120nm), segmented discrete Raman optical fibre amplifiers. Innovative product processes enabled by digital coherent technology and DSP-based monitoring of key transceiver parameters will be explored to address manufacturing yield and extended test times for arrayed transceivers. Novel designs will be developed to minimise bend losses, manual interventions, and to take advantage of robotic assembly, thereby introducing the required consistency in critical assembly processes for segmented amplifier manufacture.New equipment architectures and software-enabled re-purposing will be explored, focussed on energy efficiency, cost-effectiveness, longevity, and manufacturability. System performance will be evaluated in detailed numerical models of target networks serving great metropolises like Greater London, and compared with extensive laboratory tests in recirculating loop and extended optical fibre test beds.
