Advanced Optical Communication

Module Facts

Run by School of Computer Science and Electronic Engineering

20 Credits or 10 ECTS Credits

Semester 1

Organiser: Dr Yanhua Hong

Overall aims and purpose

The main learning objective is to treat the design and operating characteristics of advanced digital optical fibre communication systems. Students will obtain an understanding of the light source; principles of optical modulation; characteristics of optical fibre waveguides, optical amplifiers and optical receivers. In addition students will gain an appreciation of the role of these components in determining the performance of practical optical communications systems.

Course content

Indicative content includes:

  • Direct current modulation of laser diodes; limitations to direct current modulation; external modulation.
  • Light propagation in optical fibres; fibre losses and dispersion; transmission windows
  • High impedance and transimpedance receivers; optical amplifiers and repeaters
  • WDM; Mechanisms for optical switching and routing
  • Coherent Optical Communications Systems; Modulation Formats; Modulator Technologies.

Assessment Criteria

threshold

Equivalent to 50%. Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.

excellent

Equivalent to the range 70%+. Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.

good

Equivalent to the range 60%-69%. Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.
