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.
