Beschrijving

Communication networks face a potentially disastrous 'capacity crunch'. This meeting combined research in cutting edge information theory adapted to account for the nonlinear dynamics of optical systems, radical network architectures grounded in mathematics to enhance utilisation of the finite capacity, advanced material science to provide new tools and uniquely economic analysis to scope the urgency of the issues.

In recent years, society’s requirement to remain connected 24hrs per day continues unabated as corroborated by major internet exchanges in Europe (e.g. Amsterdam and London) which offer peering services connecting Internet service providers to end users and businesses. The demand from Internet based services continues at an exponential rate requiring optical transmission systems primarily based on single mode transmission fibre for point to-point and/or point-to multipoint networks. The capacity in single mode fibres (SMF) is defined by the non-linear Shannon limit. With this fundamental limit in SMF, a capacity ‘crunch’ is looming and methods to address this issue is being investigated. One of the methods proposed is space division multiplexing. Although, more SMF can be deployed, employing additional multiplexing layer such as multiple fibre cores, multiple modes or a combination of both methods in a single fibre can provide a cost effective scaling in capacity. These systems require new low loss components and fibres to access the capacity. This talk will discuss the state of the art few-mode and multimode transmission systems currently demonstrating more than 6-spatial mode transmission in a single fibre. The challenges of multiplexing into the fibres and the digital signal processing complexity will be discussed.
