Laboratory task - system for measurement of optical fibre attenuation by direct method
Jančová, Silvie ; Horváth, Tomáš (referee) ; Dejdar, Petr (advisor)
The bachelor's thesis deals with the issue of attenuation in optical fibers and subsequent measurement using the transmission method. The theoretical analysis deals with the optical fibers themselves and their transmission properties with an emphasis on dispersion and standards. The original idea of the practical part was the implementation with a photodetector. Due to the small power of the photodetector, the practical part focuses on the demonstration of attenuation measurement using measuring devices that are commonly used in practice. In the laboratories, optical fibers with a length of several tens of kilometers are used for demonstration. The laboratory task will help students to master the basic units of attenuation and gain an understanding of measurement in practice.
