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.
