Mathematical analysis and simulation of optical fiber transmission parameters
Smrž, Jan ; Šporik, Jan (referee) ; Tejkal, Vladimír (advisor)
This thesis deals with the transmission of optical fibers, their properties and method of calculation. The paper presents different types of fiber types and standards. There is a description of the connection of optical fibers with different methods, including variations joints. Further side effects are broken fibers, dispersion and attenuation. The last part is devoted to describing the program, which was part of this work. The program is used to calculate the transmission parameters of optical fibers and optical losses incurred in connection.

Measurement of optical connections
Kučera, Zdeněk ; Dostál, Otto (referee) ; Filka, Miloslav (advisor)
Communication via fiber optical cable (links) is the latest advancement of the transmission media currently used for data transmission. Despite initial problems, using of this medium in recent years has greatly expanded due to their indisputable advantages. Optical cable is a great combination of reliability and security of data transfer. Its constantly improving transmission parameters contribute to the high speeds in the long-distance transmission of data. In the theoretical part of this work some kinds of optical cables are mentioned, also the most important parameters and the most widely used methods of measurement of these cables. Apart from that other methods of joining optical cables and the most used types of optical cables are also mentioned. The values of the decline and reflection, which are led into the device after connecting these parts into the optical lines. The device using the measuring method of the reverse reflection is also described in this thesis altogether with its most important parts and the way of the display of the measured track on the graphic image of the device. The problematics of identification and decline dead zone and the factors influencing the lenght of dead zone – the ability to identify two independent events on the link patchcord of the variable lenght, is also described in details in this thesis. In the practical part a series of measurements and evaluation (numerical and graphical) of the measured values of decline lenghts and identificating dead zones of the OTDR device will be carried out.
