FTTH deployment in local networks
Horníček, Lukáš ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The master’s thesis is focused on the theoretical and practical issues of optical access networks. The first chapter of the thesis deals with the concept of the access networks known as FTTx. The second and third chapters focus on the principles and standardization of the active optical network AON P2P and the passive optical network TDM PON. The fourth chapter of the thesis focuses on the network WDM PON, wavelength multiplexes, solution concept and the LG-Ericsson EA 1100 platform. The fifth chapter of the thesis deals with the infrastructure of the optical paths for optical access networks. The sixth chapter of the thesis presents custom design of the headend for reception, processing and distribution of television broadcasting. Two custom access network solutions (AON P2P and WDM PON) for the town Bystřice nad Pernštejnem are presented in the seventh chapter. Case studies include the design of the optical paths infrastructure, central office infrastructure, end-user infrastructure, CAPEX/OPEX economic analysis and basic simulation in OptSim.

Parameters of FTTx Networks
Münster, Petr ; Křepelka, Václav (referee) ; Vlček, Čestmír (referee) ; Filka, Miloslav (advisor)
This thesis examines parameters of FTTx networks and possibilities for increases in limit values of some selected parameters. The first and second chapters describe the necessary theory for understanding the outcomes presented in the rest part of the work. In the practical part of this thesis, analysis of the condition of the optical fibers in the Czech Republic is provided. Based on the results, the impact of the polarization mode dispersion on optical access networks was assessed. The next part of this thesis is focused on the active optical networks design, depending on the cost of implementation and operating costs. The main limiting parameters of the current passive optical networks are bandwidth and insertion loss of the optical distribution network. To increase the bandwidth a system based on optical time-division multiplexing with a bandwidth of 1.28 Tbit/s has been designed and created. By using polarization division multiplexing technique the system is also more tolerant to dispersions. In the last part of this thesis, a remote amplification system was verified by measurement and simulation. Based on the obtained results, a NG-PON2 network with a functional remote amplification system with a gain of more than 10 dB has been designed in the OptiSystem software.

Laboratory exercise: Modeling of photonic communication networks
Kovaříková, Hana ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
The bachelor’s thesis deals with the issue of modern high-speed data networks and their simulation in the MATLAB Simulink environment. The theoretical part is devoted to optical networks, fibers, their properties and standards. The thesis also explains the subject of passive and active optical networks, including their components. Laboratory tasks are devoted to the simulation of the transmission of a passive optical network with a splitter and an active optical network with an amplifier.
