Amplifiers and a Digital Communications Analyzer to Enable Ultra-High Capacity Optical Fiber Transmission Systems

全球互联网流量继续以每年约40%的速度增长。推动这一增长的应用包括(i)视频流服务，（ii）基于云的存储和服务，以及（iii）机器对机器应用。这些和其他应用对增加作为互联网骨干的光纤传输系统的容量和覆盖范围产生了巨大的需求。为了满足这些需求，我们提出在光纤传输系统的前沿研究，为此我们迫切需要购买射频放大器（数量2）和数字通信分析仪。所要求的放大器和数字通信分析仪将使Plant的实验室成为世界上唯一一个拥有光纤传输系统测试平台的学术或工业实验室之一，该测试平台使用256千兆样本/秒的多通道，带宽为100 GHz。提出的研究的关键目标包括通过开发新的信道配置和相应的数字信号处理器（dsp）来最大化相干检测基光纤传输系统的比特率、容量和覆盖范围。在放大器和数字通信分析仪的支持下，计划的研究融合了数字信号处理和光纤传输系统工程的概念，从而推进光通信的基础科学。同时，由于Plant与工业界的密切合作，我们的工作将推动创新技术的发展，并有可能影响先进产品的开发。通过该计划，加拿大人将在未来3-5年内以更低的成本（例如，更低的成本，更多的数据/月）体验到互联网性能的提高（例如，更快的下载速度）。这是因为网络设备制造商（例如，Ciena，爱立信）将在下一代产品和服务中部署高容量和频谱高效光纤传输设备的计划研究所产生的创新和发明。加拿大服务提供商（如贝尔、TELUS）随后将把这些设备集成到他们的光纤网络中。反过来，这将使服务提供商能够为加拿大住宅和商业用户提供更低成本的数据和视频为中心的产品和服务。

Global Internet traffic continues to grow at a rate of ~40% per year. Applications driving this growth include (i) video streaming services, (ii) cloud-based storage and services, and (iii) machine-to-machine applications. These and other applications are creating significant demands to increase the capacity and reach of the optical fiber transmission systems that are the backbone of the Internet. In order to meet these demands, we are proposing research at the forefront of optical fiber transmission systems, for which we urgently need to purchase RF amplifiers (quantity 2) and a digital communications analyzer. The requested amplifiers and digital communications analyzer will establish Plant's lab as one of the only academic or industry labs in the world with an optical fiber transmission system testbed operating using multiple channels at 256 Gigasamples/second with 100 GHz of bandwidth. Key objectives of the proposed research include maximizing the bit rate, capacity, and reach of coherent detection base optical fiber transmission systems through the development of new channel configurations and attendant Digital Signal Processors (DSPs) for such systems. Enabled by the amplifiers and the digital communications analyzer, the planned research fuses the concepts of digital signal processing and optical fiber transmission system engineering, thereby advancing the fundamental science of optical communications. In parallel, our work will drive the development of innovative techniques with the potential to impact advanced product development due to Plant's close collaboration with industry. Enabled by the proposed researched program, Canadians will experience increases in Internet performance (e.g., faster download speeds) at reduced costs (e.g., more data/month at lower cost) in the next 3-5 years. This is because network equipment manufacturers (e.g., Ciena, Ericsson) will deploy innovations and inventions produced by the planned research on high capacity and spectrally efficient optical fiber transmission equipment in their next generation of products and services. Canadian service providers (e.g., Bell, TELUS) will then integrate this equipment into their fiber optic networks. This, in turn, will enable service providers to offer lower cost data and video centric products and services for the benefit of Canadian residential and business users.
