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.
