The study course is intended for the study of the basic knowledge (key terms, operating principles, typical applications) related to telecommunications cables systems and their applications. .
The main topics of the study course: communication lines` structures, classification of cables, insulation materials, protective coatings, electromagnetic processes in a waveguide (symmetric and coaxial cable), cable structures optimization, electromagnetic compatibility, mutual interferences (normalization and protection), shielding theory, corrosion, cable line design, construction, and operation. The study course includes both the communication line theory and practical measurements in the student laboratory. International standards related to the applications of communication lines are also addressed. Students are prepared for both practical works on communication lines and further studies in the telecommunications master programme.
