Department of Telecommunications Engineering

Synopsis:

The subject The Optical communication systems deals with a problems of how to effectively employ an optical fiber as a medium in a process of information transmission in telecommunications. In its first part students will master a basic theoretical principals of light transmission through an optical fiber with its most important parameters defined. The second part of the subject familiarize students with a system oriented problems of applying optical technology in telecommunication practice. The function and parameters of the various important optical blocks such as optical detectors, sources, attenuators, wavelength convertors, DWDM multiplexors, etc. will be analyzed here from system point of view. The final part of the subject will be dedicated to introduction of a basic optical line and network design methodology.
