Simulation and measurement of dispersions in optical access networks
Kováč, Filip ; Münster, Petr (referee) ; Šifta, Radim (advisor)
Thesis deals with detailed description of the chromatic dispersion–CD and polarization mode dispersion–PMD. In theoretical part is dismantled at the beginning of words and mathematical principles of dispersion, further distribution of dispersion in terms of single-mode and multi-mode optic fibers through compensation, either fibers (chromatic dispersion) or systems (polarization mode dispersion). Theoretical part also consult the standard ITU-T specifically in term of fibers G.652, G.653, G.655, G.656, G.657, are described and compared. The penultimate section deals with major subject and by measuring both of the above dispersions. Finally, the theoretical part is devoted to optical access networks, which describes the optical access network such as its division and at the end describes the different types networks as APON/BPON, GPON, EPON, 10GEPON and XG-PON. The practical part is divided into measurement dispersions (EXFO FTB-5700) and simulation dispersions (OptSim). Both steps use the same type and length of fiber (6 km G.653, 20, 60 km G.652). According before creating the measured and simulation diagrams are obtained fibres parameters, which are finally compared.

Classification of ICT Products and Services Designed to Manage Enterprise Resource Planning
Cieluch, Jakub ; Kováč, Filip (referee) ; Sodomka, Petr (advisor)
This bachelor thesis is concentrated on general description of Enterprise Resource Planning (ERP). It explains theoretical terms, describes concept and possibilities of use of these tools and it explains why are they useful and what benefits brings their usage. In the next part is analysis of present ERP solutions, that can be use on worldwide scale, including their common features, advantages and disadvantages. In the last chapter there are suggestions on practical use of this concept in organization.

Information System Assessment and Proposal for ICT Modification
Šejna, Tomáš ; Kováč, Filip (referee) ; Koch, Miloš (advisor)
Diploma thesis is focused on information system assessment and subsequent proposal for its modification. These changes are partly concerned on company requests, where system implemented is, but on the other hand also of development of processes in the time horizon. These proposals of changes and optimization will be afterwards presented and recommended for realization.

Data Backup and Data Storages
Budz, Patrik ; Kováč, Filip (referee) ; Kříž, Jiří (advisor)
The bachelor thesis on Data Backup and Data Warehouse is focused on ways of backing up data and its practical use in a detailed proposal for BPM Sport s.r.o., which deals with the sale of sport accessories. At the beginning of the thesis are presented the theoretical starting points related to this issue, namely the analysis of backup and archiving, analysis of carriers for backup and archiving. The second part deals with the analysis of the current state of backup in the chosen company. Synthesis occurs in the following chapters, there are several ways to solve the current state of backup in the company based on the findings. The last chapter - the discussion, contains the evaluation of the results and the determination of the concrete solution.

Reproducibility and accuracy of polarization mode dispersion measurements
Kováč, Filip ; Brouček,, Jan (referee) ; Šifta, Radim (advisor)
Thesis is divided into two parts. The first part is written rather in theoretical way. It deals with general formation of the dispersion mathematically and verbally. It focuses on the chromatic and polarization mode dispersion. Different types of optical fibers for category G.65X are mentioned as well in connection with the ITU-T. Further attention is drawn first to compensation and then the measurement both of the mentioned dispersions. The thesis describes also analyzers and their main features. The second part is devoted to practical measurements of polarization mode dispersion. In the beginning there are described the components used for construction of the optical measurements and topologies. It is followed by an analysis of an each optical link. The results of these measurement methods and their mutual comparisons are at the end of this section. Measurements in temperature chamber is the subject of a further practical part, which from the beginning captures the essential features of the temperature chamber. This is followed by a description of the measurements, analyses and final valuation depending on the amount of polarization mode dispersion versus the temperature.
