Optical cables in modern data centres
Hejtmánek, Ondřej ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The essence of this study was to evaluate the issue of fiber optic and data cables in modern data centers. To compare and evaluate optimal design parameters were chosen as follows: Performance, reliability, installation time, flexibility, weight and size, requirements maintenance and training and the total price. The introductory chapters describes structure of the data center and network bases and storage technologies used in data centers. Particularly a local area network Ethernet and storage technology, DAS, SAN and SAS. Followed by a metallic and fiber optic cabling. For metallic cabling are used primarily PiMF cables. The fiber optic cabling emphasis was placed on multimode fiber OM3 and OM4. The main point of this study was to compare three types of installation metallic and three types of fiber optic cabling. MRJ-21 solution, pre-terminated system and standard installation of the so-called notch technique for metallic cables. For optical cabling has been chosen MPO solution, pre-terminated system and standard installation by welding fibers. In the end were compared and evaluated various solutions. The main focus was placed on the parameters of performance, reliability and installation time. The optical systems were rated the best solution MPO and preterminated system. Results were similar for the metallic cabling, where most of the parameters of the solution satisfies MRJ-21 followed by pre-terminated system. Standard installation for both types of cables in data centers too has not worked. All types of installations have been tested in practice and measured at different times during install.

Data centre project - structured cabling
Hejtmánek, Ondřej ; Dostál, Otto (referee) ; Filka, Miloslav (advisor)
This master’s thesis is concerned with analysis of cabling and cabling systems in data center and with their projection as follows. The part of the work is aimed at the measurement parameters of metal cables which are used in data center with noise. The first part is focused on analyzing the structure of the data center and cabling used in it. The structure of the data center is based on the TIA-942 and consists of an entrance room, main distribution area MDA, horizontal distribution area HDA , zone distribution area ZDA and the equipment distribution area EDA. Divided into backbone cabling and horizontal cabling and use standard and pre-terminated cabling. The measurement results of structured metal cabling with noise are discussed in the next part. There were used these types of cables UTP, FTP and S/FTP. The measurement was performed in the electricity substation and in the laboratory of electromagnetic compatibility. The third part of this work deals with the actual design of structured cabling for the data center. In the first design we use the standard installation, the second preterminated cabling. For both types of installation cost statement is processed (CAPEX). Thesis is also completed with DC design drawings and rack drawings.

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.

Structured cabling system design for hotel
Novák, Lukáš ; Jordán, Vilém (referee) ; Sedlák, Petr (advisor)
This thesis deals with a proposal of structured cabling in a business object of Pentagon Hotel. The proposal addresses the use of horizontal and backbone infrastructure of the building using both metallic and fiber wires. The proposal does not deal with active parts of the network, it addresses just their recommended connection. The thesis also deals with the financial aspect of the proposal in the form of a complete budget.
