Course content
|
The course includes the history of optical communications, an overview of passive elements (fibers, multiplexers, dispersion compensators, etc.) and an overview of active elements (optical switches and amplifiers, high-speed coherent transmission systems). The course also includes the latest topics presented at prestigious conferences such as ECOC or OFC. Attention is also paid to new applications such as very precise time transfer, ultra-stable frequency or sensing. Exercises will focus on actual work with optical components and on the measurement of their parameters. Students will solve real problems they may encounter in practice. Lecture content: 1. Introduction to optics, history of optical communications. 2. Optical fibers, their types, uses. 3. Linear phenomena and their effect on signal transmission. 4. Nonlinear phenomena and their effect on signal transmission. 5. Most important measurements: dispersion, attenuation, OTDR optical reflectometry. 6. Passive optical components. 7. Optical signal amplification. 8. High-speed modulation, basic types of transceivers. 9. New types of transceivers, terabit Ethernet, and Optical Transport Networks (OTN). 10. Coherent high-speed transmission systems. 11. New non-data applications. 12. Optical transmission security (QKD). 13. Technological trends - the future of optical networks. Exercise content: 1.- 3. Introduction to the basic principles and elements of optical networks. 4. - 6. Optical fibers, passive components (splitters, multiplexers), active components (amplifiers). 7. - 9. Basic measurements used in the practical operation of optical networks (attenuation, OTDR). 10. - 11. Spectral measurements of various types of optical transmitters. 12. - 13. Assembly and measurement of a simple optical transmission route.

Assessment methods and criteria
|
Written examination
The course will be completed by a multiple choice examination with a maximum of 60 points. Exercises will be graded with a maximum of 40 points (10 per block). The minimum score for passing the exam is 50. There will be two make-up dates (dates to be arranged). There are no other requirements for the student, this is a basic introductory course.
