Measurement and monitoring of optical fiber infrastructures
Baláž, Dominik ; Tomašov, Adrián (oponent) ; Münster, Petr (vedoucí práce)
This bachelor thesis deals with measurement and monitoring methods on optical path. The basic principles and transmission using optical fibers, optical fibers, band splitting and transmission characteristics such as attenuation and dispersion are discussed. The principle of wave multiplexing and recommendations according to ITU-T standards are also presented. Afterwards, measurements on optical fibres are described, instruments and methods for measuring and monitoring the optical path are presented in detail, and these instruments are compared in terms of their parameters and individual functions. In the practical part, cleaning of connectors, inspection of connectors, measurement of optical path without bending and with different bend radii using OTDR, direct method and measurements using FC BERT application, which is a substitute for the monitoring system, are described, the values from these measurements are evaluated both numerically and graphically.
