Leakage of information through active and passive elements in optical fibre infrastructures
Spurný, Vladimír ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
This bachelor thesis deals with the problem of information leakage from optical fiber infrastructures, both from the fibers themselves and from passive and active elements. The first part is devoted to a theoretical description of the transmission of information over an optical fiber and the function of individual components. The next part is focused on the theoretical analysis of possible information leaks. In the last - practical part, there will be an examination of some of the previously described possibilities of information leakage with subsequent analysis and a proposal for risk minimization.

Analysis of information leakage from optical transmission system
Šimon, Václav ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
This bachelor thesis deals with the structure of an optical transmission system. It focuses mainly on the transmission part of the system. It describes its parts and the functioning of the components used. It also deals with the risks of information leakage at various levels of the system (backbone networks, distribution and access networks, optical fiber). The practical part examines the issue of 3 possible risks. Firstly is measured the effect of unauthorized connection of a splitter to the optical path, then the eavesdropping in dense wavelength division multiplexing networks and the last measurement deals with the eavesdropping of the upstream signal in GPON access networks.
