1 Scope
This part of IEC 60825 provides requirements and specific guidance for the manufacture and safe use of laser
products and systems used for point-to-point or point-to-multipoint free space optical
data transmission in the wavelength range from 180 nm to 1 mm. This document only
addresses the open beam portion of the system. If portions of the equipment or system
incorporate optical fibre that extends from the confinements of the enclosure(s),
the manufacturing and safety requirements in IEC 60825‑2 apply to those portions only. This document does not apply to systems designed for
the purposes of transmitting optical power for applications such as material processing
or medical treatment. This document also does not apply to the use of systems in explosive
atmospheres (see IEC 60079‑0).
Light-emitting diodes (LEDs) employed by free space optical communication systems ( FSOCSs ), used for the purpose of free space optical data transmission, do not fall into
the scope of this document. This document covers lasers employed by FSOCSs used for the purpose of free space optical data transmission.
This document:
• provides information to protect people from potentially hazardous optical radiation
produced by FSOCSs by specifying engineering controls and requirements, administrative controls and
work practices according to the degree of the hazard; and
• specifies requir...
