Design of EMC optical converter
Štěpánek, Adam ; Hruboš, Zdeněk (referee) ; Krutílek, David (advisor)
Master's thesis is focused on designing optical converter for EMC measurement transfering signal through noisy enviroment. First part contains analysis of electromagnetic interference and its coupling and measurement, especially types of probes for interference maesurement. Next part passing through designing of optoelectric and electrooptic converter with digital intensity modulation. Last part is about realization of optical converter.

Distribution of analog signal by optical fiber
Stiburek, Martin ; Rampl, Ivan (referee) ; Šporik, Jan (advisor)
Bachelor's thesis is focused on analog signals via optical fibers. The thesis is divided into two parts. The first part describes the various transmission paths, and compare their advantages. Further describes the optical fiber itself, particularly the negative influences in the transmission, i.e. signal attenuation and dispersion. Attention is paid to the physical elements of the optical transmission system. As the light sources, light detectors, optical amplifiers and most optical transceivers. There are selected three different types of optical transceivers and compared according to their characteristics. Conclusion the first part is devoted to fiber optic signal distribution to the customers. This technology transfer is known as FTTH (Fiber to the Home). The second part is ocuses on the practical realization of optical transmission system. It consists of two optical transceivers - transmitter optical signal and optical signal receiver. Transmission system is designed for transmitting analog television signals without a soundtrack. After construction of the system according to the proposed transfer scheme was successfully simulated using the optical cable length of 3m. However, the circuit allows for its further expansion in order to improve the reproduced signal. Circiut boards were made by using EAGLE program. The result is a functional transfer system.

Model of the metropolitan optical network
Prudík, Jiří ; Hudcová, Lucie (referee) ; Křivák, Petr (advisor)
The purpose of this master’s thesis is foremost to provide a simple guide how to build elements of optical metropolitan area network. The basic model consists to sequence of construction, network topology, passive and active parts. The collection contains examples of alternative technology such as Wireless LAN with different frequency. The optical network construction based on optical cable, fibres, splices, trays, adapters, connectors and active parts for example a lot of media convertor models. After that there are demonstrating type of wavelength division multiplexer used in metropolitan area network – passive planar PCL splitter. One of the passive planar splitter are used to increase optical fibre channel. At the end of the collection a simplified examples of used measurements – optical time domain reflectometry and optical fibre transmission. Contains standard protocols or reflectogram. The conclusion of this thesis summarizes costs of FTTb (Fibre To The Building) model of optical metropolitan area network in Czech republic and future contribution for society.
