W1 - Mitigating Linear and Non-Linear Optical Transmission Impairments by Electronic Means Summary Since the collapse of the infamous bubble and the fall of capex in the telecom sector, the focus in optical system research has shifted from attaining capacity and distance records at any cost, to reproducing already proven performance at a much lower cost. Robustness and adaptivity have also been placed high in the list of desired features, as opposed to maximized performance. Despite the great progress of optical technologies, optics is still being rated as very expensive and also scarcely reconfigurable or difficult to deploy and maintain. The quest for cost saving has therefore concentrated on replacing certain optical technologies and devices with electronic counterparts, especially in the realm of the mitigation of fiber linear and non-linear propagation effects and of link/component impairments. This shift of paradigm has been enabled by the impressive breakthroughs in analog and digital high-speed electronics, today making it possible to perform advanced signal pre- and post-processing up to 10 Gbit/s, with 40 Gbit/s in view. Various forms of receiver equalizers and advanced decision algorithms (such as MLSE), as well as astounding signal pre-processing and synthesis in transmission, have been theoretically devised and also proved in landmark experiments. Over just the last two years, this area of research and investigation has experienced an exponential rise in interest and, for the first time, it has brought together optical communications with traditional communications and information theory, thus attracting towards optical communications a larger community of experts and researchers. This workshop aims at collecting leading-edge and breakthrough contributions from the main actors in the field. Speakers will be selected among the leaders in the area, to inform on the state-of-the-art in this rapidly evolving area and to deliver thought-provoking, forward-looking talks outlining the possible future avenues that research could take. Open discussion will be encouraged during the workshop. This workshop is organized by the Virtual Department on “Transmission Techniques for Broadband Networks” of the FP6 Network of Excellence e-Photon/ONe ( www.e-photon-one.org ).
