Renovation of Structured Cabling in Office Building
Rybáková, Alena ; Šarbort, Jakub (referee) ; Ondrák, Viktor (advisor)
This bachelor’s thesis is about computer networks. It deals with analysis and design of a computer network for an office building. In this object, there is a need for restructuring and optimisation of the current network because there are two companies which will be merged together into one office building and also because the current network state is unsuitable.

Optimization of Company Information Infrastructure.
Luska, Jiří ; Holub, Zdeněk (referee) ; Ondrák, Viktor (advisor)
The thesis discusses the problems of data infrastructure in the company Instalační materiál – Herman s.r.o., which dealing with sale and comlex services in plumbing. The current state of computer networks is generally poor, combines current and older technologies, resulting in problems with the functionality of the sale system. Therefore the company decided to invest in upgrading IT. The goal is to evaluate the current situation and propose a range of optimization to an extent that meets the criteria of the company as a customer

The quality of assembly in data transmission
Šalplachta, Milan ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The content of this work is theoretical and practical an analysis of transmission characteristics of structured cabling and related effect of assembling, which directly affects the characteristics of channel. Individual treshold limits of channel parametres, as technological methods of montages are outgoing from corresponding european specifications.

Software support for design of data distribution
Karásek, Stanislav ; Mišurec, Jiří (referee) ; Mrákava, Petr (advisor)
This work serves as a basic guide to designing such a data distribution. The first chapters deal with the basics of computer networks. They are mentioned types of networks and major hardware elements and topology. The work is mainly focused on a LAN connection to the buildings and the extensive use of technological objects. The following is a basic description of the transmission cables, among which today is dominating type of twisted pair cable. The future is based on cable-based optics, however. Their brief description is here as well. For better orientation in how to design work is included in the chapter on structured cabling. Mentioned are sections of the cabling system, the differences between them and their purpose. Furthermore, the category of twisted pair, that played an important role in structured cabling systems for the past 20-30 years. Description of technical standards, defining structured cabling, terminating the theoretical part. The practical part describes the computer programs, focusing on the design of data distribution. Of these selected AutoCAD Electrical 2011, as the best and most acceptable user tool. The program is broken down and explained the importance of its basic features and mechanisms. For a better understanding of the work is created with the program video tutorial the written commentary. These videos are designed for absolute beginners, but some knowledge will appreciate the more experienced designers. This series of videos made from the student's actions in the AutoCAD preview to the final drawing the cable into the prepared plan. Floor plan of the building together with a random series video tutorial is located on the CD, which is attached to this thesis.

Assemblying effect on cable lines quality
Dočkal, Martin ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
In the first part is explained what actually a structured cabling is. Its beginning, from what and why it was created. Its history when at the beginning were applied unbalanced coaxial cables, those were later replaced by balanced cables. In cabling for TVs are still used coaxial cables. Balanced cables are according to type named UTP, STP, FTP, and so on. Whit growing popularity of this type of cabling and its wide spread application was necessary to set some rules, standards, specifications and demands, how to build up the cabling from project to realization. According to these rules is the system built so there are strict rules for length of subsystems and interfaces and the whole appearance of the structure cabling. Next important point is projecting of cabling that is related to the previous points and when it’s finished, we should strictly follow it. With the project is closely connected characteristic of this cabling as attenuations, cross-talks and other transmission parameters which are measured in the practical part. In the second part is spoken about all the parts of which the structured cabling consists - metallic and optical connecting elements and cables. There are also mentioned their mechanical, electrical and transmission features. In the third part is described influence of man on the quality of structured cabling and the most common causes of lower quality and the ways how to prevent this from happening and how to manipulate with cabling not to destroy it. The final (fourth) part considers the measurement. There are measured qualities of metallic wires as the attenuations, delay, cross-talks on the near- and far-end, impedance and resistance. To all the features are mentioned schemes of the measurement on the twisted pairs. The measurement is divided into two parts. In the first part are measured five types of balanced cables of different length, category and damage influencing quality of these cables. In the second part is measured one balanced cable if it’s corresponding with category 5 for that t was made and if it would be possible to use it also for higher category 6. Values are tabularly sorted in tables.

Computer Network Design
Bartoň, Jan ; Kavan, Jiří (referee) ; Ondrák, Viktor (advisor)
The goal of this thesis is to analyze the current state of the customer's computer network and his requirements. Then the changes and the way of their realization were proposed. The next part of the thesis are the description of appropriate components, selected technologies and the detailed description of the implementation process, including blueprints.

Research into the appropriateness of diverse multimedia cabling applications
Tichý, Ondřej ; Kapoun, Vladimír (referee) ; Škorpil, Vladislav (advisor)
The reader can find a summary of metallic structured cabling in this thesis. It means there is described progress of this cabling and the specifications of the cabling systems. There are also described all types of these cables and some of connectors. The types of cable are summed in the table at the end of this part. In another part there are shown some aplications used for structured cabling. In the futher part there are described tests defined in the specifications in more detail. The most importatnt part of this thesis is focused on various tests. Firstly, there were chosen typical representative of the cables. It was: the data cable (Category 6), S/STP and MediaTwist cable. These cables were underwent the standard tests described above and theirs results are appended on the attached CD. In the last part of this thesis there are intrinsic tests of fitness cables to the multimedia signal. Of course, the tests were chosen to measure cable to obtain the most suitable type of cable. However, these tests were not standard measurement. There were simulated occasions from the practise. The goals of this thesis were to achieve the results, to compare them between each other and to make a decision, which cable is the most suitable for the multimedia signal. Definitely, this thesis should be sufficient at least for people who keep track of structured cabling. Eventually, the clear decision was made from these testings. MediaTwist cable is the most suitable type for the multimedia signal, because the signal is being recognized correctly in almost every case even if the long length. The result from the testings in more detail can be found at the very end of this thesis. So, if you are interested, please, continue in reading.
