Design of a laboratory for lecturing critical infrastructure
Chudý, Martin ; Jordán, Vilém (referee) ; Ondrák, Viktor (advisor)
This bachelor’s thesis focuses on design of computer network, primarily on the level of physical layer of the ISO/OSI model. Design is designated for building a new laboratory for lecturing critical infrastructure. Within the laboratory we need to choose transmission technology and draft their placement. New laboratory will be created by merging two separated classrooms.

Spectral characteristics in fiber optics
Chleboun, Jiří ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
This bachelor’s thesis is focused on the influence of attenuation and dispersion glass and plastic optical fibers in optical transmission system. Theory of optical transmission is discussed in the theoretical part, it is defined term like spectral attenution characteristic and its division into transmission bands. Sources and detectors are itemized further, which are used for optical transmissions in fiber optics. The thesis describes the most occured effects, which influenced transmission parameters of optical fiber, like optical attenution, dispersion and aspectual polarization dispersion. Theory of plastic optical fibers is processed at the end of theoretical part of thesis. It is also processed advantages, disadvantages and useage of plastic optical fibers and they are consequently compare with glass fibers. Comparison is focused mainly on attenuation, transmission properties and useage on these types of fibers in telecommunication. Representation of spectral attenution characteristics in programme MATLAB is practical output of the bachelor´s thesis. Created programme approximates points which are got from measure optical attenuation by the Lagrange interpolation polynomial.

Transmission system for polymer optical fiber
Kubík, Martin ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
Bachelor's thesis deals with the transmission of signals via plastic optical fibers. First part contains basic principle and parameters transmission of light beam via fiber. The most common types of plastic optical fibers are analyzed, theirs characteristic parameters and trends in the development of this type of transmission medium are listed. In the second part is designed and implemented the proper integration of the optical transmitter and receiver to transmit signals via plastic optical fiber. The advantage of the implemented circuit is its modularity, so it is possible to further easily extend the system. Laboratory task is prepared for use system in the laboratory.
