Měření útlumových parametrů optického coupleru po namáhání vysokým výkonem

Abstract

The bachelor thesis studies a passive optical splitter or optical coupler. Main goal is to determine the effect of high power on attenuation parameters of the coupler, including theoretical analysis of this device. The theoretical part will mention basic information related to the light, light transmission in optical fiber, passive optical networks and issue of coupler itself. The practical part deals with the actual measurement of the impact of high power on attenuation parameters of the coupler. The essential parameters of the measurement are insertion losses, split ratios, total losses, homogeneity of the losses and directionalities. The work is based on the assumption of an increase loss and its subsequent decline by relaxation of the material. It is a prime view of this the problem.
