Overview

Diploma Thesis from the year 2002 in the subject Electrotechnology, grade: 1,0, University of Dortmund (Lehrstuhl fur Hochfrequenztechnik), 39 entries in the bibliography, language: English, abstract: Next generation optical communication systems will be characterized by increasing data rates, high signal powers and dense wavelength division multiplexing (DWDM). In future-optical networks channels will be routed through complex, meshed networks (ASTN, Automatically Switched Transport Networks, ITU-T Recommendation G.808 0/Y.1304). These networks will be able to setup transparent optical paths without converting the optical signals to electrical signals. In all-optical networks the physical impairments and degradation effects play an important role. There is a multitude of degradation effects like dispersion, noise, crosstalk, fiber nonlinearities, polarization dependent loss, etc. To enable a fast setup and the best choice of one of the available paths, the signal quality along the whole transmission distance has to be evaluated very fast. Ideally, only a single figure of merit (FOM), e.g. the bit error rate (BER), will be computed, which incorporates all degradation effects. Therefore it is important to characterize the different physical impairments analytically. Signal distortions can be measured by an eye opening penalty (EOP) and degradation effects due to noise by the optical signal-to-noise ratio (OSNR). The goal is to find and calculate these impairments from the signal parameters (modulation format, data rate, duty cycle, channel spacing, etc.) as well as the route parameters (fiber lengths and parameters, EDFA powers, etc.). Due to the need of fast routing algorithms, time-consuming numerical methods or a complete system simulation are not practical. In addition, it is not possible to linearly accumulate the different degradation effects. The focus of this work is to find analytical or heuristic formulas for each degradation effect. These approximation f

Author Information

Stephan Pachnicke wurde 1977 in Dortmund geboren. Von 2000-2001 absolvierte er ein Masterstudium in Information Engineering an der City University, London, Grossbritannien. Sein Studium der Elektrotechnik an der TU Dortmund schloss er 2002 mit dem Grad Dipl.-Ing. ab. 2005 wurde er zum Dr.-Ing. der Elektrotechnik promoviert - ebenfalls an der TU Dortmund. Im Jahr 2005 beendete er ausserdem ein Dipl.-Wirt.-Ing. Studium an der FernUniversitat, Hagen. Seine Habilitation wurde ihm im Januar 2012 verliehen fur Forschungsarbeiten uber Optische UEbertragungsnetze . Gleichzeitig wurde er zum Privatdozent der TU Dortmund ernannt. Von 2007 bis 2011 arbeitete er als Oberingenieur am Lehrstuhl fur Hochfrequenztechnik, TU Dortmund. Anschliessend war er bei der Firma ADVA Optical Networking SE in der Abteilung Advanced Technology (CTO Office) beschaftigt und leitete u.a. EU-finanzierte Forschungsprojekte zu optischen Zugangsnetzten der nachsten Generation. Ausserdem erforschte er Konzepte fur die Konvergenz von Fest- und Mobilfunknetzen sowie Datenzentren der nachsten Generation. Seit 2016 ist er Professor an der Christian-Albrechts-Universitat zu Kiel und leitet den Lehrstuhl fur Nachrichtenubertragungstechnik. Gleichzeitig ist er Direktor des Instituts fur Elektrotechnik und Informationstechnik. Er ist Autor bzw. Ko-Autor von mehr als 100 wissenschaftlichen Veroeffentlichungen, darunter 5 Bucher und 19 Zeitschriftenbeitrage. Stephan Pachnicke erhielt verschiedene Auszeichnungen fur seine wissenschaftliche Arbeit darunter den ITG-Preis 2012 des VDE, den Dissertationspreis 2006 der TU Dortmund sowie den VDE Preis Rhein/Ruhr 2002. Er ist Mitglied des VDE/ITG und Senior Member des IEEE.
