This thesis deals with an optimization of Triple play services and security in optical access networks. The first chapter provides theory basics which are necessary for results evaluation. The second chapter describes optical access networks with their parameters such as transmission speed, split ratio, line code, bit error rate etc. defined by ITU. Next chapter summaries the current state in optical networks construction field according to the European Union developing plan. The practical part of this thesis is divided into several subchapters. The significant part of the thesis is dedicated to the security of passive optical networks and design of proper security model for current networks. For this purpose, the unique parameter time propagation Tprop, with the novel security model was developed. Next part of the thesis provides an analysis of control traffic and data traffic in the gigabit passive optical networks. For a novel algorithm in activation process in gigabit passive optical networks the measurement results were used. The novel algorithm decreases the total time needed for this process. The last but one subchapter deals with an ILP model for Triple Play services. The last subchapter contains the own implementation of the transmission converge layer in VPIphotonics simulation tool.
