Optical Networking
The objective of the module is to introduce the student to the main building blocks required for high capacity data transmission over optical networks, and describe how these systems operate within the transport and access layer of the overall telecommunications network and to provide an overview of the worlds photonic networks in terms of operational features, topology and architectures and services provided by the photonic networks. The mathematics will be limited to the absolute minimum but the students will be encourage to fill gaps in information theory, and communication essentials with private study.

Prof. Liam Barry
School of Electronic Engineering
Dublin City University
Liam Barry received his BE (Electronic Engineering) and MEngSc (Optical Communications) degrees from University College Dublin in 1991 and 1993 respectively. From 1993 until 1996 he was a Research Engineer in the Optical Systems Department of France Telecom's Research Laboratories (CNET) in Lannion, France. During this period his research involved the use of ultra short optical pulses in high capacity networks, and as a result of this work he obtained his PhD Degree from the University of Rennes. In February 1996 he joined the Applied Optics Centre in Auckland University as a Research Fellow, and in March 1998 he took up a lecturing position in the School of Electronic Engineering at Dublin City University, where he established the Radio & Optical Communications Laboratory. From April 2006 until February 2010 he served as Director of the Rince Institute, a multidisciplinary research centre with over 120 participating researchers, and he is currently a Principal Investigator for Science Foundation Ireland. He has been a TPC member for the European Conference on Optical Communications (ECOC) since 2004, and a TPC member for the Optical Fibre Communication Conference (OFC) from 2007 to 2010, serving as Chair of the Optoelectronic Devices sub-committee for OFC 2010.
