REAL-time monitoring and mitigation of nonlinear effects in optical NETworks


The exponential surge in the global data traffic driven by the skyrocketing proliferation of different bandwidth-hungry on-line services, such as: cloud computing, on-demand HD video streams, on-line business analytics and content sharing, sensor networks, machine-to-machine traffic arising from data-centre applications, the Internet of Things, and various other broadband services, brings about the escalating pressure on the speed (capacity) and quality (bit error rate) characteristics of information systems. It is well recognized nowadays that rapidly increasing data rates in the core fibre communication systems are quickly approaching the limits of current transmission technologies, many of which were originally developed for communication over linear (e.g. radio) channels. It is widely accepted that the nonlinear transmission effects in optical fibre represent now a major limiting factor in modern fibre-optic communication systems. Nonlinear properties make optical fibre channels considerably different from wireless and other traditional linear communications channels. There is a clear need for development of radically different methods for coding, transmission, and (pre & post) processing of information that take the nonlinear properties of the optical fibre into account and for training of a new generation of engineers with expertise in: optical communications, nonlinear science methods, digital signal processing (DSP), design of implementable algorithms. From the industry perspectives, design of practical and implementable processing algorithms requires knowledge of ASICs and real world conditions and restrictions. The mutli-national & multi-interdisciplinary REAL-NET project will provide timely doctoral training for 6 PhD students through industry relevant research in the fast growing area of high practical relevance and will lead to development of novel practically implementable disruptive techniques for fibre-optic communications.
