With this module, students gain an understandig of optical networks (covering aspects from the physical layer to networking functions), and are able to analyse them answering questions such as: what are the components of an optical network, how are optical networks evolving, how can optical networks be reliable, how are optical networks planned, controlled and managed.

Introduction to optical networks: why optical networks? Main drivers; Optical fiber and transmission effects; the optical network components; Routing and Wavelength Assignment; Impairment Constraint Based Routing; Optical Circuit Switched networks; Optical Packet Switched networks; Optical Burst Switched networks; Network control with introduction to routing and signaling protocol; Network management; Failures that may occur in an optical network and their prevention and detection; Optical network reaction to failures; Optical access networks.

The knowledge of following modules are recommended: - Broadband Communication Networks

Learning method: In addition to the individual methods of the students consolidated knowledge is aspired by repeated lessons in exercises and tutorials. Teaching method: During the lectures students are instructed in a teacher-centered style. The exercises are held in a student-centered way. Furthermore, a list of hop topics and research issues will be provided so that students are encouraged to study on of these topics in detail and give a presentation.

The type of examination is adapted to the different learning outcomes: Knowledge-based learning results are examined during a written exam with 90 minutes duration. The capability for learning some particular topics more in detail will be examined through specific literature studies during the semester and the presentation of selected topics. The final grade is composed of the following elements: - 70% final exam - 30% literature search and presentation of targeted topic.
