TRANSPORT SOLUTIONS FOR OPTICALLY AMPLIFIED NETWORK (WERNER WEIERSHAUSEN AND MALTE SCHNEIDERS) Werner Weiershausen received his Dipl.-Ing. degree in electrical and RF engi- neering from Technical University of Braunschweig in 1992, including AlGaAs based VCSEL research at University of Ulm. From 1992 to 1997 he has been with the Research Center of Deutsche Bundespost/T-Nova and 1997 with the University of Technology, Darmstadt, as a scientist in the fields of InP based semiconductor technology, integrated optics and fiber components. In 1998 he joined the Photonic Systems and Optical Networks Group at T-Systems, first working on theoretical and experimental research in the fields of high-speed optical WDM transmission and measurement methodology, later being project leader for different projects on R&D and technical consulting for optical networks. 2008 he changed to the Technical Engineering Center of Deutsche Telekom, working on the strategic evolution of the next-generation optical packet platform. Werner Weiershausen has been active in several national and European R&D projects (ACTS, IST, COST, BMBF) and different standardization bodies (ITU-T, IEC, DKE). Since 2003 he has been serving as SPIE Editor, Symposium Chair for Optics East Symposium and Conference Chair at Photonics West, USA. He is author or co-author of more than 80 publi- cations, conference contributions and patents. Since August 2008 Werner Weiershausen is working for the management board (in the role of CSO) of the Finnish startup company Luxdyne Ltd, Helsinki, on sub systems for optical access (FTTH, PON). werner.weiershausen@telekom.de Malte Schneiders has more than nine years experience in the area of Optical Transport. He received his Diploma degree in electrical engineering from the Technical University of Dortmund, Germany in 2001. During his employment at Deutsche Telekom Group he has contributed already to several strategic projects, as well as to national and international research activities on the optimization of optical transport networks and high-speed transmission systems.
