<title>Safety problems in free space optical transmission</title>
2006
The paper is focused on safety of exploitation of optical transmission devices in free space. The subjects concerning propagation of "open" optical stream and its' possible dangerous influence on environment, mainly living organisms are discussed. An attempt to evaluate an installation and exploitation of transmitting devices was made, concerning dangers, requirements, recommendations and restrictions, concluding from accepted safety standards (IEC 60825- 1 :2005, EN 60825-1 :2005 and in Poland PN-EN 60825-1 :2005 "Safety of laser devices - Equipment classification, requirements and user's guide"; IEC 60825-12:2004, EN 60825-12:2005 and in Poland PN-EN 60825-12:2005 "Safety of free space op…
Safety uses of optical fiber communication systems
2005
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.
