Abstract

The diploma thesis studies a passive optical splitter or coupler. The aim is to determine the effect of thermal thermal ageing on attenuation parameters of the coupler, theoretical analysis of device. The theoretical part provides basic information related to the issue coupler. The practical part deals with the measurements of the impact of thermal ageing on the attenuation parameters of the coupler. The essential parameters of the measurement are insertion loss, split ratio, total losses, homogeneity of the losses and directionalities.
