Hazard level assignment
"Hazard level" refers to the potential hazard from laser emission at any location in an end-
to-end optical fiber communication system that may be accessible during service or in the
event of a failure. The assignment of hazard level uses the AELs for the classes.
Hazard levels for optical transmission equipment are assigned in either of the following
two ways:
• the actual output power from the connector or fiber cut.
• if automatic power reduction is used, the output power at the connector or fiber cut at
one second after automatic power reduction takes place, provided that maximum
output and restart conditions are met.
Classification of optical telecommunication equipment
Optical telecommunication equipment is generally classified as IEC Class 1 or
FDA/CDRH Class I, because under normal operating conditions the transmitter ports
terminate on optical fiber connectors.
According to the IEC 60825-1 Edition 1.2 (2001) standard, Class 1 laser products are safe
under reasonably foreseeable conditions, and according to the FDA/CDRH - 21 CFR 1040
standard, Class I levels of laser radiation are not considered to be hazardous.
