The optical fibre communication network forms the backbone of the global communication infrastructure on which all Internet traffic relies. Since their commercial deployment in the 1980s, optical fibres have been considered as offering plenty of capacity and being able to sustain the growth in data traffic. However, the tremendous traffic growth rates experienced in the past decade call for a substantially faster optical data transmission preferably over the existing fibre deployments. This research project is dedicated toward serving this need.The proposed research revolves around the concept of optical superchannels, which combine multiple wavelength channels to accomplish higher end-to-end rates. To increase the amount of traffic supported by existing fibres, our research team will develop methods to pack data more densely into these superchannels and to allow superchannels to adapt to the current demand for traffic through a optical fibre network. This will be accomplished through sophisticated signal processing methods that organize the data transmission at the optical transmitter and that compensate for the various impairments and in particular crosstalk of densely packed data streams at the receiver. As typically the case for the effective development of communication methods, this part of the project will heavily rely on computer simulations for performance evaluation. In the second part of the project, we will demonstrate the feasibility of implementing the developed innovations in hardware. We will target an implementation in a field-programmable gate array, a device typically used in academia and industry to explore the design space and prototype integrated circuits. The research team consists of experienced faculty members and enthusiastic graduate student researchers and is supported by experts from one of the leading vendors of optical fibre communication solutions. The research program will provide excellent training opportunities for the students, making them ready to join the Canadian information and communication technology sector after graduation.

光纤通信网络构成了所有互联网流量所依赖的全球通信基础架构的骨干。自1980年代的商业部署以来，光纤被认为具有足够的能力并能够维持数据流量的增长。但是，过去十年中经历的巨大交通增长率要求在现有的纤维部署中优选的光学数据传输速度更快。该研究项目致力于满足这一需求。拟议的研究围绕着光学超级通道的概念，该概念结合了多个波长渠道以实现更高的端到端率。为了增加现有纤维支持的流量，我们的研究团队将开发方法更密集地包装到这些超通道中，并允许超级通道通过光纤网络适应当前对流量的需求。这将通过复杂的信号处理方法来完成，该方法在光学发射器上组织数据传输，并补偿接收器的各种损伤，尤其是密集包装的数据流的串扰。通常，对于有效开发通信方法的情况，该项目的这一部分将在很大程度上依靠计算机模拟进行绩效评估。在项目的第二部分中，我们将证明在硬件中实施开发的创新的可行性。我们将针对现场可编程门数组中的实现，该设备通常用于学术界和行业，以探索设计空间和原型集成电路。研究团队由经验丰富的教职员工和热情的研究生研究人员组成，并得到了光纤通信解决方案领先供应商之一的专家的支持。该研究计划将为学生提供极好的培训机会，使他们准备在毕业后加入加拿大信息和通信技术领域。
