Description of achievement and assessment methods

The type of examination is adapted to the different learning outcomes:Knowledge-based learning results are examined during a written exam with 60 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:

  • 80% final exam
  • 20% literature search and presentation of targeted topic

Exam type: written

Exam duration: 60 min.

Recommended requirements

The knowledge of following modules are recommended:

  • Broadband Communication Networks


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.

Study goals

After completion of the module students have an understandig of optical networks (covering aspects from the physical layer to networking functions), and are able to analyse them in the aspects of what the components of an optical network are, how optical networks are evolving, how optical networks can be reliable, how optical networks are planned, controlled and managed.

Teaching and learning methods

  • Lerning method: In addition to the individual methods of the students consolidated knowledge is aspired by repeated lessons in exercises and tutorials.
