FSO transceiver for link quality estimation
Novák, Marek ; Vlček, Čestmír (referee) ; Wilfert, Otakar (advisor)
Tato diplomová práce pojednává o zmírnění bitové chybovosti bezkabelového optického spoje s užitím principu reciprocity aplikovaného na komunikační kanál, spolu s možností kódování přenášených dat. V této práci je implementováno LDPC a Reed-Solomonovo kódování pro jejich vyhovující vlastnosti. Zbytková rámcová chybovost je vypočtena a k dispozici jako výstup systému, který je implementovaný v hradlovém poli (FPGA).

Communication protocols emulator
Fabulec, Martin ; Dejdar, Petr (referee) ; Jablončík, Lukáš (advisor)
The content of this work is the analysis of commonly used serial protocols RS-232 and RS-485 and their transmission using the optical fiber. The work deals with the analysis of the actual problematic and the connection design of the optical fiber system, communication through optical fiber and communication interface. The design of the communication protocol emulator and the verification of the functionality of the transmission system are also discussed. The theoretical part deals with optical components such as optical receiver and transmitter, SFP module and the description of the RS-232 and RS-485 interface. The practical part mentions the connection proposal and subsequent data transfer.

Economy of ventilation units
Kratochvila, Lukáš ; Pech, Ondřej (referee) ; Hejčík, Jiří (advisor)
This bachelor’s thesis discuss methods of comparing air handling units from the economy of operating stage aspect. Introductory chapters have research character and they are about ventilation and air handling units. In further chapters, there are described and demonstrated 3 methods for comparing units. These methods are compared in the conclusion.

Media Converters and Optical Switches
Branč, Martin ; Reichert, Pavel (referee) ; Münster, Petr (advisor)
This Master´s thesis provides an overview of wired networks, its parameters, used standards and the deployment possibilities. Moreover, it includes the overall overview about optical networks, its parameters, maximum bandwidth, reachable distances as well as the advantages and disadvantages in comparition with wired networks. The project describes network elements which are used in the optical access network such as media convertors, optical switches etc. The practical part includes results of testing of the network devices in various scenarios. To get a comparable result, the real throughput, the power of each device and compatibility of devices from different producers were measured. At the end I have suggested few scenarios with the usage of optical switches and media convertors for extension of the current optical network. The calculation of costs for building and operation of the network is also included.
