Dispersion effects in high-speed optical networks
Filip, Tomáš ; Šporik, Jan (referee) ; Tejkal, Vladimír (advisor)
This bachelor’s thesis is focusing on optical transmission principal, its transfer mediums and furthermore also with focusing on its advantages and disadvantages. First half of this thesis focuses on adverse influences, which affect signal transmission in optical networks, on dispersion influences, especially on Polarization Mode Dispersion (PMD). Second half of this thesis deals with measuring of properties of optical fibers, largely chromatic and polarization mode dispersion, used methods and its principals. Furthermore, there are mentioned current compensation possibilities. The seventh chapter deals with optical route simulation in OptiSystem and testing chosen compensation methods for bit rate 40Gb/s. In the last chapter there are elaborated results of real optical route measurements for Masaryk University.

Design of the optofiber sensor system to monitoring change of length
Jelínek, Michal ; Stehlík, Jiří (referee) ; Mikel, Břetislav (advisor)
The bachelor´s thesis deals with design and verification of optical fiber sensor system for measuring changes of length. This system is designed to shape monitoring of the nuclear power plant containment. The principle of measurement, design and realization of the first version is described in the work. Principle of measurement and functionality of the whole system was verified by measurement of specially prepared reinforced concrete console. The console was prepared in the way to simulate behaviour of containment of the nuclear power plant. Within development of system there were prepared of optical fiber sensors with Bragg´s grattings which are later used for measurement.

Pressure Sensing Using Ltcc Technology
Somer, Jakub
This paper deal with the design, manufacturing and measurement of optical pressure sensors produced using Low Temperature Co-fired Ceramic technology. There is brief overview of measurement methods used for pressure sensor interrogation. Benefits and problems regarding measurement methods are discussed. Pressure transducers are based on the change of the light spectrum reflected from the Fiber Bragg Grating integrated in the sensor. Low Temperature Co-fired Ceramic structure with membrane was used for the forming of a pressure transducer. Samples of fiber optic sensors are calibrated using reference pressure measurement and characteristics of the sensors are measured. Pressure sensors for different pressure ranges were measured and tested.

Spectral Change Based Optical Sensors
Eliáš, Josef
This paper is focused on optical sensors based on spectral characteristics change. Optical sensors are widely used for industrial, robust and noise proof measurement. There are measurement techniques for mechanical tension, temperature, pressure, displacement, vibration and so on. This article provides brief description of selected optical sensors based on Fabry-Perot and fiber Bragg grating principle. The article includes basic sensor description, theory of operation and measurement setup and expected measurement ranges and resolutions.
