Optical Transmission Systems

Lecturer:

Jiří Vodrážka (gar.), Pavel Troller

Tutor:

Jiří Vodrážka (gar.), Jiří Hájek

Supervisor:

Department of Telecommunications Engineering

Synopsis:

The subject familiarize students with a fundamental functions and design methods of telecommunication transport and optical networks. In the first part of the subject the emphasis is being laid upon understanding of key functions of a synchronous transmission technology - SDH in relation to optical technology, firstly a systems based on utilization of dense wavelength multiplexing methods - DWDM. The second part of subject is aimed to provide students with fundamental understanding of functions of a varied optical line and network components such as optical amplifiers, DWDM transponders, optical crossconnects, etc. and their relations to IP based transport networks.
