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.

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程序包括（i）视频流服务，（ii）基于云的存储和服务，以及（iii）机器对机器应用程序。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，我们提议在光纤传输系统的最前沿进行研究，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。所需的放大器和数字通信分析仪将使普兰特实验室成为世界上仅有的拥有光纤传输系统测试台的学术或工业实验室之一，该测试台使用多通道以 256 Gigasamples/秒和 100 GHz 带宽运行。拟议研究的主要目标包括通过为此类系统开发新的通道配置和附带的数字信号处理器（DSP），最大限度地提高相干检测基础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，计划中的研究融合了数字信号处理和光纤传输系统工程的概念，从而推进了光通信的基础科学。与此同时，我们的工作将推动创新技术的发展，由于 Plant 与行业的密切合作，这些技术有可能影响先进产品的开发。在拟议的研究计划的支持下，加拿大人将在未来 3-5 年内体验到互联网性能的提高（例如，更快的下载速度）和更低的成本（例如，以更低的成本每月获得更多数据）。这是因为网络设备制造商（例如 Ciena、爱立信）将在其下一代产品和服务中部署高容量和频谱效率光纤传输设备计划研究中产生的创新和发明。加拿大服务提供商（例如贝尔、TELUS）随后会将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提供成本更低的以数据和视频为中心的产品和服务，造福加拿大住宅和商业用户。
