- Abstract
- In this paper presents the results of articulator measurements and the research of physical parameters of informative signal in the fiber optical channel speech information leakage. With the adapter type SC-SC a high sensitivity detected to a parasitic acoustooptic modulation and crosstalk, such structural heterogeneity of optical networks as plug-in connections of optical cable. It was found that the sensitivity to the acting information acoustic field by using standard equipment was comparable with a conventional microphone sensitivity. On the basis of experimental data, it was concluded about the need for the perfection of appropriate regulatory and methodological documents and the development of new effective means of protection.
