Gives requirements and guidance for the safe use of optical fibre or control communication systems, or both, where optical power may be accessible at a great distance from the optical source. It does not apply to optical fibre systems primarily designed to transmit optical power for applications such as material processing or medical treatment. It is based on, but not equivalent to, IEC 825-2:1993.

This Standard provides requirements and specific guidance for the safe use of optical fibre or control communication systems, or both, where optical power may be accessible at great distance from the optical source. It does not apply to optical fibre systems primarily designed to transmit optical power for applications such as material processing or medical treatment.Throughout this Standard, light emitting diodes (LEDs) are included whenever the word 'laser' is used.The objective of this Standard is to provide the following:(a) Protect people from optical radiation resulting from optical fibre communication systems.This requires the introduction of engineering requirements and work practices according to the degree of hazard.(b) Lay down requirements for manufacturers and operating organizations in order to establish procedures and supply information so that proper precautions can be adopted.(c) Ensure adequate warning to individuals of hazards associated with optical fibre communication systems through signs, labels and instructions.(d) Reduce the possibility of injury by minimizing unnecessary accessible radiation and to give improved control of the optical radiation through protective features and provide safe usage of products by specifying user control measures.NOTE: Appendix A gives a more detailed rationale for this Standard.Classification of laser products, including optical fibre transmission equipment and test equipment, is covered in AS/NZS 2211.1.
