Researcher, Dr Peter Ossieur of the Tyndall National Institute, UCC, has developed a receiver chip that allows fibre-to-the-home networks to reach 100km and beyond.

This compares to 20km in today’s commercially deployed networks.

This chip, the first of its kind, will enable the simplification of the network infrastructure. Dr Ossieur explains, “The recent fast adoption of bandwidth intensive services such as high definition IPTV, cloud computing, video conferencing, etc. is putting today’s broadband access networks under severe pressure. Adoption of fibre-to-the-home technology is only part of the solution. Network operators are now considering more disruptive approaches whereby optical access and metro networks that link cities are integrated into a single all-optical system. Such an approach streamlines today’s networks and eliminates power-hungry and expensive local exchanges. These new networks need a new generation of component technologies that can especially support the required longer reaches (>100km) and bitrates (10Gb/s and beyond).”

“We are now looking to commercialize a product version of the first prototype in close collaboration with indigenous Irish industry as well as various major international players in this field,” he said.

Dr Ossieur presented his work during the week at the Optical Fibre Communications Conference, LA, USA on next generation Optical Access Networks. The linear burst-mode receiver chip was developed with funding from Science Foundation Ireland in the world renowned Photonics Centre at Tyndall National Institute, Cork, Ireland. First experimental results were presented as a prestigious postdeadline paper at the European Conference on Optical Communication,Geneva, September 2011.
