Security Risks in Passive Optical Networks
Šimoník, Jan ; Jeřábek, Jan (referee) ; Horváth, Tomáš (advisor)
This diploma thesis deals with the historical development of passive optical networks, according to the standards that was defined by International Telecommunication Union (APON, BPON, GPON, XG-PON and NG-PON). Further, the thesis describes the security of passive optical networks, but also a security threats which the deployment and use of passive optical technology carry. In the introductory chapters of this thesis the passive optical networks are described. The following is a description of the standards of passive optical networks in terms of their historical development. The next part is dedicated to the security of passive optical networks and possible security threats. In conclusion a description of the practical part of this thesis is given -- rack assembly, which will serve for future testing. The basic configuration of the optical line terminations that are fitted in the rack is also described. The last part of this diploma thesis is dedicated to the testing of selected security risks, which was described in the theoretical part of this thesis.

Testing of optical networks
Šimoník, Jan ; Horváth, Tomáš (referee) ; Filka, Miloslav (advisor)
The aim of this bachelor thesis is to describe testing of optical networks physical layer by norms and recommendations (CSN, ITU and RFC). The first chapter provides a description of the individual optical fibers, their division and a brief description of each type. In the next part of this thesis, the methods and procedures for testing the various parameters of optical networks are described, according to specific standards and recommendations. The issue of testing quality of services is also described, primarily focused on triple play services, which are operated at optical access networks. The following is a description of the issue of access and transport networks, a draft of methodology for testing the physical layer of these networks is given. In conclusion, there is a chapter describing the practical measurements made on a passive optical network. In the annexes of this thesis the limit parameters of optical fibers used for the measurements and draft of the content for measuring protocol are listed.
