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.

Standards for application of polymer optical fibres
Stiburek, Martin ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
The aim of thesis is description of polymer optical fiber (POF). In particular, focusing on their application and its associated standardization. After explaining the principle of signal transmission by polymer fibers, glass fibers are compared with the polymer fibers. The attention is then paid to the types of POF and their connectors. Another part is engaged in standards of polymer fibers, according to their area of application. Following chapter describes the application of polymer fibers in practice, especially in the automotive industry and sensor technology. Standalone chapter is dedicated to deploying POF fibers in LANs. It mentions comparasion with copper and wireless networks, summarizes the advantages and disadvantages. Chapter also provides an overview of the components used in POF - optical converter, switch with optical interfaces, optical network card, etc. In the practical part is created the design of home network for two-storey family house. The proposal was implemented by CableProject CAD software, first using copper cabling (UTP category 5e) and then using polymer fibers. Finally, both proposals are compared with each other. It has been made detailed financial analysis, compared performance of instalation and methods of cable instalallation. The practical part is also dedicated to measuring the parameters of POF networks, the impact of the attenuation loss, explores methods of joining glass and polymer fibers and is engaged in IPTV transmission simulation in real conditions.
