Optical information transmission - transmission security
Kondicz, Dávid ; Čučka, Milan (referee) ; Filka, Miloslav (advisor)
The submitted work deals with issues of optical transmissions and its security. We will become familiar with a variety of transferability of information, based on which we can assess the advantages and disadvantages of each technology as compared to optical information transmission. Based on acquired information we will try to implement interception of optical communication of cable TV provider.

The utilization of POF in access networks
Doležal, Ondřej ; Šporik, Jan (referee) ; Filka, Miloslav (advisor)
In this work, the reader familiares with plastic optical fiber (POF). Firstly are mentioned the basics of the optical transmission. Then there are the main features and parameters POF and a historical overview, detailed description of the types of POF, their important strengths and weaknesses, comparison with glass fiber, installation, available POF connectors and procedure of measurements and a summary of key findings from the practice, including a description of existing experiments and projects. The second part focuses on the use of POF in access networks. There are described present trends in access networks, an overview of optical access networks and explaination the concept with the inclusion of POF in optical networks (FTTX). Furthermore, there are possibilities of POF fibers in segment of local networks and their readiness for advanced network services, such as IPTV. The penultimate chapter contains design test polygon and final part summarizes all findings and results of this work.

Experimental work with POF - Polymer optical fibers
Doležal, Ondřej ; Urban, František (referee) ; Filka, Miloslav (advisor)
In this diploma thesis, the reader is familiarized with polymer optical fiber (POF). Firstly is mentioned theoretical background of optical fibers and optical transmission. The following are the basic properties and significant parameters of POF, a more detailed description of each type POF and their essential advantages and disadvantages in comparison with established optical fibers based on glass. The next chapter describes the area of practical issues: working with fibers and fiber installation, as well as the available connectors and methods of measurement of POF. Closely are analyzed knowledge of the practice, including the utilize in the aerospace and automotive industries, as well as in industrial networks, access data networks and local area networks. The practical part includes the measurement of basic transmission and mechanical parameters, including analysis of the results. The conclusion summarizes all the findings and results of this work, including possible future developments.

Optical transmission applications in industries
Worbis, Vít ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The aim of the semestral work term use of optical transmission in the industry is to find the right equipment for communication in industrial applications, which would lead to better control and management of these applications. My show almost seamless connection between the device, which is controlled by another device such as a computer. The first chapter shows how inside the core optical fiber and reflected beams are then carried around the skylight. The second section lists the differences between the copper and fiber cabling, there is described why metallic line slowly destroyed and replaced him fully optics. In the third chapter, I focused on the optical fiber, what are its characteristics, from which parts are made and what is distributed. In the fourth part shows the optical transmitters for multimode and singlemode optical fibers, which are differences between them, which are produced and with what characteristics, etc. In the fifth chapter is applied to a network of possible involvement in the industrial zone, is designed only as they could theoretically be industrial zone controlled by the machine. In the sixth part of the thesis I have tried to design a laboratory task that consists of those optical converters. It is only a small sample, as used in the industry far more extensive involvement.

Architecture of FTTx networks
Beníšek, Jan ; Šalamon, Tomáš (advisor) ; Příklenk, Oldřich (referee)
Bakalářská práce popisuje architekturu FTTx sítí. Snaží se odpovědět na otázky, jaké technologie a topologie jsou využívány a jaké architektury FTTx jsou nejčastěji zastoupeny. Pro pochopení základních souvislostí je zařazena část, která se týká podstaty přenosů po optických vláknech, jednotlivých typů vláken a základů optických sítí. Pro doplnění je popsána současná situace rozšíření FTTx sítí dle jednotlivých kontinentů: Asie, Evropa a Severní Amerika. Praktická část je reprezentována analýzou trhu optického přístupu k Internetu v ČR. Součástí Bakalářské práce je reálná případová studie optické přístupové sítě, vybudované společností Cabel Media s. r. o. Případovou studii doplňuje analýza návratnosti vložených prostředků.
