Supervisor:
Department of Telecommunications Engineering
Synopsis:

The course deals with the use of optical radiation for the transmission of information. The aim is to acquaint students with the functions of important components used in advanced optical communications systems and networks. Students will learn how to design practical optical fiber link and the network. Students will receive theoretical knowledge for the implementation of a all-optical photonic networks in the future, which will be based on a combination of wavelength multiplex with an all-optical switching.
