EU-Project ADDAPT

Improving the Energy Efficiency in Optical Data Communications
TUD scientists start the EU-project "ADDAPT - Adaptive Data and Power Aware Transceivers for Optical Communications"

Optical transceiver modules, which are applied in modern data and telecommunications for data transmission, usually cannot adapt to the current demand of the user or the net. They therefore operate at the maximum performance all the time, which means that they are neither energy- nor resource-efficient. For this reason, the EU-project "ADDAPT - Adaptive Data and Power Aware Transceivers for Optical Communications" aims at developing a dynamic electro-optical transceiver module that can transmit data very fast and is highly energy-efficient at the same time. To achieve this, the scientists will design electronic circuits, electro-optical components and modules whose performance (above all, the bandwith) and power consumption can be adapted to the current conditions of the net (e.g. the current data load). "This is a completely new approach in this area that would contribute to a significant reduction in power consumption of such a system", said Professor Frank Ellinger, the project coordinator. "In addition, CO2-emission and operating costs of such a system would be reduced as well", adds Dr Ronny Henker, the operational manager of ADDAPT.

The Information and Communications Technology (ICT) brings us advantages for our professional and daily life: we store data in the cloud and download it from there, we buy the bus ticket on our smartphone and we check our emails when we are on the bus or use the Internet for finding information. But due to the daily and multifaceted usage of ICT, its energy consumption is increasing strongly. Currently, the ICT accounts for 3% of the worldwide energy consumption; and its power consumption doubles every five years. Scientists are therefore looking for ways of reducing the energy hunger of the ICT. For this purpose, the Chair for Circuit Design and Network Theory at the Faculty of Electrical and Computer Engineering of the Technische Universität Dresden started the project ADDAPT.

The kick-off meeting took place on 16 January 2014. The project runs until 30 April 2017 and is funded by the Seventh Framework Programme (FP7) of the European Union. The project has a total grant of € 4.8 million. Within the frame of the project, the TU Dresden cooperates with seven partners (three large-scale und three small- and medium-sized enterprises, one university) from seven European countries.
