Design of an optical access network
Kučera, Jan ; Filka, Miloslav (referee) ; Münster, Petr (advisor)
Bachelor Thesis deals with the optical access network, mostly with the passive ones. It aims for current trends of users connecting to the optical access network by using FTTx connections, moreover the thesis aims on DOCSIS technology and G.Fast. Due to a focus on DOCSIS and G.Fast metallic elements are discussed too. In the practical part of bachelor thesis the theoretical knowledge in solving of access optical networks are applied. The proposal involves the technical solution of the building optical access networks, technology, attenuators balance and calculation of network. Thereafter there is discussed the simulation of the proposed project, verification of the correctness of the proposal and its evaluation.
FTTB Network Design
Reichert, Pavel ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The purpose of this master’s thesis is to explain the issues of the FTTx network design. The main idea of this work is to describe to readers the methods of the designing the optical access networks. Especially we will speak about the building technologies and different topologies used in a practice. The different technologies of optical access networks’ building and various parameters, which are necessary to take into account in the designing of these networks, will be introduced. In the theoretical part, methods of measurement, which are like the needed part of each optical access networks’ building, will be described. Two purposes of the FTTB networks with all proprieties will be made and offered. One purpose will be solved by Point to Point topology and the second purpose will be solved by Point to Multipoint topology. Following the confrontation one of these purposes will be chosen and realized. By ITU recommendation, measurements will be performed on the built optical trace. The final protocols will be elaborated from these measurements. The built trace with all final reports will be prepared for assignment to the subscriber.
Application of the new technologies in optical access networks
Ryšavý, Jan ; Münster, Petr (referee) ; Šifta, Radim (advisor)
The aim of the thesis is get theoretical knowledge of the latest components used in optical access networks and subsequently get knowledge practical experience in design and simulation of these networks. The thesis is divided in two different parts. In the first part of this work are given theoretical knowledge AWG multiplexers and other modern elements used in optical access networks. The second part deals with the design and simulation of optical access networks using wavelength and time division.
Partial renovation of metropolitan optical network infrastructure
Cichra, Petr ; Lávička Otakar, Mgr., MU, https://is.muni.cz/osoba?prezdivka=xlavick1 (referee) ; Novotný, Vít (advisor)
This bachelor thesis is focused on rebuilding of active metallic-optical network in locality Brno – Zábrdovice, in the streets Šámalova, Kuldova a Krokova on purely passive optical network based on xPON technology with possibility of further expansion of capacity. The partial goal is a thorough analysis of the current state and the main proposal is the solution of modernization of the existing network infrastructure into xPON and then implement this proposal. The theoretical part of the bachelor thesis describes the problems associated with these technologies with regard to current and future trends in the construction of optical networks. Furthermore, the economic intensity of the investment in this reconstruction will be evaluated.
Implementation of Pasive Optical Network
Klaška, Patrik ; Jordán, Vilém (referee) ; Ondrák, Viktor (advisor)
This bachelor´s thesis is focused on making a complete proposal optical access network for emerging buildings, and later connect other sites in the village Hrušky near the town of Slavkov u Brna. The main goal is the implementation of FTTx networks, describe the problems associated with them with regard to current and future trends in the construction and management of these networks.
The data transfer technologies in optical access networks (FTTx)
Matušík, Lukáš ; Míča, Ivan (referee) ; Reichert, Pavel (advisor)
The objective of diploma thesis is describe problems connected with designed of FTTX networks and bring the reader problems of data transmission in optical acces networks the type of PON. In the introduction are mentinoned individual technologies that already operate, and there are describe advantages disadvantages of the use topology point-to-point and point-to-multipoint. In the following chapters are dealt with problems with data broadcasting in the direction from final participant. In the other part of diploma thesis are described elements, that were used for the proposed transmission route. The own PON acces network was presented on the basis information obtained by comparing the various networks and the elements involved in them. The network presented in conclusion diploma thesis is involved in topology point to multipoint. This transmission route is simulated in the program that allows the involvement of network by the user’s need with real values. The acces network is simulated for different transmission speed and different distances. The assesment of created optical route results from the measured values, theirs source is program OptiSystem, these values are summarized in the final chapter.

Modern optical access networks
Třetina, Vítězslav ; Münster, Petr (referee) ; Šifta, Radim (advisor)
The bachelor’s thesis is about technology of passive optical networks. In the introduction, the paper focuses on introducing the basic functional elements of the networks and describes the different possibilities for implementing fiber optic lines as close as possible to the user. The main goal of the theoretical part of this work is the analysis of the various standards of passive optical networks. These specifications are described in the second and fourth chapter, where are discussed their different technical parameters. Particular attention is given to the technology of wavelength division multiplexing. The conclusion of the theoretical part is devoted to the description of the measuring instruments which are suitable for measuring C/DWDM systems. The practical part of this thesis is divided into two sections. The task of the first section is about creating two animations where the first of them shows the principle of passive optical networks based on wavelength division multiplexing (WDM - PON). The second animation is focused on the practical demonstration of a combination of wavelength and time division multiplexing (WDM/TDM - PON). The second section of the practical part consists of simulating multiple scenarios of passive optical networks in the OptSim 5.2. In these scenarios are searched for maximal possible parameters PON networks such as reachable attenuation, reachable distance or split ratio.
