The EU-funded INVENTION project aims to develop a cost-effective approach that will boost the capacity of Europe's optical fibre network to handle the ever-increasing demand for high-bandwidth applications such as video streaming and cloud computing.

The development of the EU’s fibre optic networks is a key part of the infrastructure needed to keep Europe innovative and competitive. The use of fibre optics – where thin, flexible glass fibres transmit light signals over long distances – is fundamental to how people and businesses access high-speed internet applications and data.
Passive optical networks (PONs) are the most widely employed network technology in Europe. However, PONs will soon reach full capacity due to increasing demand for bandwidth-hungry, video-intensive applications and the proliferation of cloud computing.
As the cost of laying down new cable to meet increasing demand is prohibitively high, INVENTION, funded through a Marie Curie research fellowship, aims to provide an affordable solution to overcome the looming bandwidth ‘capacity crunch’.
The project’s research fellow, mathematician Christian Sanchez, is working on innovative concepts that involve employing coherent detection technology with low-cost and simplified optical receiver architectures.
He plans to address the cost requirements of optical networks by implementing a combination of innovative signal processing techniques and digital-sign-processing (DSP) algorithms.
Improved internet access and speeds for individuals and businesses will foster innovation, growth and competitiveness in the European digital economy.
