ABSTRACT: Information leaks through regular fiber optic communications is possible in the form of eavesdropping on conversations, using standard fiber optic communications as illegal measuring network. The threat of leakage of audio information can create any kind of irregular light emission, as well as regular light beams modulated at acoustic frequencies. For information protection can be used a means of sound insulation, filtration and noising. This paper discusses the technical possibilities of countering threats by monitoring the optical radiation to detect eavesdropping.
