Řešení zakončení optických vláken pro VLC aplikace

Abstract

The objective of this diploma thesis is to create an optical fiber transmitter in the software aplication LightTools and to find the most suitable mesh positions and terminations in numbers 7 and 19 considering the distribution of optical intensity on 1/8 of the sphere with 3 dB fluctuation of optical power. The following goal after the simulation in this software is to create a real fiber transmitter with a configuration that matches the most efficient achieved results in the simulation. After constructing and measuring the fiber transmitter results, the simulated and real measured results are compared. At the beginning of the work the relations of optical networks are explained. It is a summary of the study of light, optical quantities, optical fiber and fiber-free networks and components used in them and also optical radiation safety. Following is the simulation and measurement procedure.
