Objectives

This course aims to present the state of the art in optical communication systems, either digital or analog, presenting the fundamental concepts needed for system design. Emphasis will be given to high bit-rate systems with optical amplification and next-generation optical networks (networks of transport and access), presenting technological solutions to overcome the current limitations of fiber and devices.

Learning outcomes and competences

Understanding the specific characteristics of the optical fiber transmission systems, its advantages and limitations.
- Knowledge of project-oriented optical communication systems
- Ability to search for information on research in advanced optical systems and networks for future generation
- Capacity Analysis, simulation and design of such systems

Learning outcomes are acquiring the skills oriented to the project as well as the ability to identify relevant topics for research in networks and next generation optical systems.
