Design and simulation of passive optical network PON
Mikauš, Jiří ; Krajsa, Ondřej (referee) ; Reichert, Pavel (advisor)
The aim of master's thesis was to demonstrate chosen PON network in simulation software OPNET Modeler. The work deals with passive optical networks. In particular, solutions that are based on the transmission of Ethernet frames. EPON and 10GEPON standards are described in theoretical section. EPON Standard was introduced already in 2004. Newer 10GEOPN is back compatible, which is ideal as a suitable solution for modern network with a high data rates demands. The practical part describes process of developing network nodes for passive optical network. EPON model was developed in simulation tool, that demonstrates basic features of the standard IEEE 802.3ah. The simulation results are demonstrated in last section.

Interface for management of optical line termination in passive optical network
Kováč, Dávid ; Holík, Martin (referee) ; Horváth, Tomáš (advisor)
This bachelors thesis deals with the creation of a graphic user interface for the configuration of optical line terminal for passive optical networks. The aim of the thesis was to make the configuration of optical line terminal easier and more convenient. The graphic user interface allows the user to configure ONTs, display all connected ONTs, show the event log and to configure alarm profiles. The theoretical part of the thesis deals with getting acquainted with passive optical networks and getting familiar with how the graphical interface was created. Furthermore, there are the programming tools and the extension used to create the GUI, an explanation of how and why each part of the GUI was created, including the classes and the methods which were used, how the testing went and the results. At the end of the thesis is a manual of what needs to be installed to make the GUI work and how to use it.

Partial renovation of metropolitan optical network infrastructure
Cichra, Petr ; Lávička Otakar, Mgr., MU, https://is.muni.cz/osoba?prezdivka=xlavick1 (referee) ; Novotný, Vít (advisor)
This bachelor thesis is focused on rebuilding of active metallic-optical network in locality Brno – Zábrdovice, in the streets Šámalova, Kuldova a Krokova on purely passive optical network based on xPON technology with possibility of further expansion of capacity. The partial goal is a thorough analysis of the current state and the main proposal is the solution of modernization of the existing network infrastructure into xPON and then implement this proposal. The theoretical part of the bachelor thesis describes the problems associated with these technologies with regard to current and future trends in the construction of optical networks. Furthermore, the economic intensity of the investment in this reconstruction will be evaluated.

Methodology for FTTH optical network measurement
Gajdoš, Jaroslav ; Reichert, Pavel (referee) ; Filka, Miloslav (advisor)
The main topic of this master thesis is a FTTH measurement methodology of optical networks and its specific features 9 compared with other measurement methodologies. Also, the use of the FTTH measurement methodology: an example of measurements of a passive network with splitter 1:8 and analysis of the results of these experimental measurements. The first part of the thesis concerns itself with the description of optical networks and characteristics and features of the FTTH networks. A detailed description of the passive optical networks is provided: e.g. the optical network unit ONU, the optical line termination OLT, and, most importantly, the passive optical splitter. The wavelength division multiplex 9 WDM 9 which is used in passive optical networks is also described in detail. The chapter on measurement methodologies focuses in detail and provides many examples of currently used measurement methodologies of these networks. The best results are currently achieved with the OTDR methodology. The second part of the thesis concentrates on the description of the measurement of a passive optical network with splitter 1:8 using the methods described in previous chapters. As conclusion, a detailed analysis, assessment of the results and their usefulness when put into practice is provided.
