Optical Wavelength Division Multiplex
Kavický, Martin ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
This bachelor's thesis is orientated to problems about optical networks and possibilities of transmision more than one optical mode trough single fibre. Components, which create optical path, are described there. I was concerned with kinds of fiber couplers, optical multipexors and demultiplexers, proper souces and receivers of optical radiation, possible optical amplifiers and in not least turn single types of wavelenght division multiplexing. In practical part I propose possible ways of verification of activity of wavelenght division multiplexing and optical path components, as is EDFA amplifier, or circulator. As insertion of thesis, I created concept of active task, in which will students meat with meassuring optical power after way through EDFA amplifier, which they will tune.

Verification of parameters of passive optical components on short wavelengths
Látal, Michal ; Filka, Miloslav (referee) ; Vojtěch, Josef (advisor)
Semestral thesis deals with the basic theoretical knowledge in the field of optics, light propagation and optical fibers. It describes in detail the optical transmission system and its associated issues, such as the attenuation of optical fibers or differently caused dispersion. The main part of this work is a description of each passive optical elements, their production technologies and applications in optical communications. Within the optical connection its radiation sources and detectors of optical radiation are explained. The last practical part is focused on the measurement of insertion loss provided by passive optical components.

Measurement of basic parameters of optical and optoelectronic components
Beneš, Pavel ; Látal, Michal (referee) ; Münster, Petr (advisor)
This diploma thesis deals with optical and optoelecronic components. The first part of the work describes the optical paths and methods of their measurement. The second part describes the coupler, circulator and isolator. Further described is a laser diode, a photodetector and a modulator. The third part describes the measurement procedure of the coupler, circulator, isolator, laser diode, photodetector and modulator. The measured values are compared with the catalog values.

OTDR optical path analyzer
Šimková, Barbora ; Tomašov, Adrián (referee) ; Dejdar, Petr (advisor)
The aim of this master's thesis was a theoretical analysis of OTDR issues, analysis of OTDR device components, as well as basic parameters of this device. The thesis also includes a theoretical analysis of reflections, scattering, and various types of connectors. In the practical part, a circuit design for OTDR measurement was developed and subsequently implemented. The circuit was realized using the Red Pitaya development board and Koheron laser. Additionally, a circuit for direct method measurement was also created. In the LabView development environment, a program was created, including a graphical user interface. A laboratory task was also designed to provide a basic understanding of OTDR measurement issues.
