The course can be found on nanoHUB.org at https://nanohub.org/resources/29411 where other downloads are available. This course is an introduction to the fundamentals of fiber optic communications, which constitute the backbone of the internet. The course will start with a refresher on the operation of key components needed for an effective fiber optic communication system, and then show how these components interact at a system level. Finally, the course will conclude with outlook for future research in extending the capabilities of these networks to higher bandwidths and quantum-secured communications. This course is part of a Purdue University initiative that aims to complement the expertise that students develop with the breadth at the edges (https://engineering.purdue.edu/ECE/Academics/PMP/courses) needed to work effectively in today's multidisciplinary environment. These serious, short courses require few prerequisites and provide a general framework that can be filled in with self-study when needed.
