Safety and Agency Approvals
1.1
Legal Reference and Safety Standards
Operation of optical communication systems is subject to national and/or international safety
regulations (GT12W with optical SFPs).
We refer to:
European directive 2006/25/EC on the minimum health and safety requirements regarding the
exposure of workers to risks arising from physical agents (artificial optical radiation),
International standard IEC 60825-1 (2007-03): Safety of laser products - Part 1: Equipment
classification and requirements, and
International standard IEC 60825-2 (2010-12): Safety of laser products - Part 2: Safety of optical
fiber communication systems (OFCs).
Generally, the operator of a communication system is responsible for its safe operation. Some
important points to respect are e.g.
Assessment of hazard levels at accessible locations,
Care for the proper installation and maintenance,
Measures for the safe operation, like access control and adequate staff training.
