Safety uses of optical fiber communication systems

The paper is focused on problems of optical radiation, which occurs in systems and devices of optical fiber communications, during their usual exploitation, and in breakage situations. Mainly in aspects of open (possible to disconnect) fiber optic optical system and/or accidental affection of electromagnetic radiation (in visible and infrared spectrum) on human being. Considerations about safeness of using fiber optical systems and devices were examined on the basis of directions and obligatory standards or propositions of changing them as results of newest research.
