CEET and Bell Labs patent technique to increase the energy-efficiency of broadband

3 November 2011

The University of Melbourne’s Centre for Energy-Efficient Telecommunications (CEET) has filed its first patent in conjunction with Alcatel-Lucent’s research arm, Bell Labs.

The patent, announced by Professor Rod Tucker, Director of CEET, describes a new approach to increasing the energy-efficiency of optical fibre broadband access networks.

This breakthrough is a result of CEET’s devotion to innovation in energy-efficient networks and technologies that will reduce the impact of telecommunications on the environment.

“We are very pleased to announce this research breakthrough, which has resulted from collaborations between CEET researchers and researchers at Bell Labs in Murray Hill, New Jersey,” said Professor Rod Tucker. “The key idea in this research is a more energy-efficient approach to encoding data on the optical signals that are sent from the telephone exchange to the home.”

“Fibre to the premises technology is recognized worldwide as a key “last mile” access technology.  It is already a very energy-efficient platform for broadband access.  The new invention shows that a fibre-based network to become even more energy efficient in the future than they are today,” said Dr Alan Lee, Project Chief Investigator.“One attractive feature of this invention is that it will be possible to make significant improvements to broadband fibre networks as a natural part of future planned upgrades to higher bandwidth.”

As part of a national tour this week, CEET and Bell Labs today hosted a public lecture and innovation showcase at the University of Melbourne. Bell Labs Chief Scientist, Dr Alice White said, “energy efficient telecommunications is a key research focus area for Bell Labs globally and we are very proud to be partnering with the University of Melbourne for important work in this area. It is very exciting to see the first firm results of this collaboration and I look forward to further successes in the future.”

About CEET

The Centre for Energy-Efficient Telecommunications is a partnership between the University of Melbourne, Alcatel-Lucent and the State Government of Victoria. The Centre is carrying out research that aims to improve the energy efficiency of the Internet and keep the total energy of the Internet under control as the amount of data on the network increases and as the number of users expands. Governance of the Centre is shared between Alcatel-Lucent’s and the University of Melbourne
