Possibilities of increasing the throughput of optical fiber industrial networks
Čičmanský, Tomáš ; Münster, Petr (referee) ; Filka, Miloslav (advisor)
Diploma thesis deals with problems of industrial networks using optical fiber as the main transmission lines. The task of the diploma work is to study and summarize the issues of industrial networks as well as the ways to increase their transmission capacity. In telecommunications and computer networks are generally used multiplexes, thanks to which we are able to achieve the desired transmission capacity. Consequently, the following work deals with the selection of the adequate solutions using described multiplexes as well as other transmission methods. The aim of the diploma work is to compare various renovation techniques of an old industrial network. Using this network as an example the work should demonstrate the individual problems and their solutions while considering different types of methods used. Based on the price, the performance and the difficulty to install other devices and transmission media we are able to select the appropriate solution for optical link.

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.

Distributed acoustic sensing system data analysis applied for perimeter protection
Senčák, Jakub ; Dejdar, Petr (referee) ; Tomašov, Adrián (advisor)
Táto práca sa zameriava na snímanie optických vlákien pomocou distribuovaného akustického snímania. Cieľom bolo vytvoriť multiplatformovú aplikáciu na vizualizáciu údajov získaných zariadení Optasense ODH-F. Táto práca bola motivovaná nedostatkom aplikácií s otvoreným zdrojovým kódom na vizualizáciu pre snímanie pomocou optických vlákien. Práca vysvetľuje distribuované akustické snímanie a efekty rozptylu svetla, ako je Rayleighov, Ramanov a Mandelsamov-Brillouinov rozptyl. Výsledkom práce je webová aplikácia. Aplikácia sa skladá z dvoch hlavných častí - server napísaný v jazyku Python a klientská časť implementovaná vo frameworku Svelte. Výsledky tejto práce možno použiť ako základ pre vytvorenie vizualizačného softvéru pre distribuované akustické snímanie.
