Laser class
4
Notes:
1. Class 3R only exists if the maximum power is within five times the Accessible Emission
Limit (AEL) of Class 1. Please refer to the IEC 60825-1 Ed. 1.2 (2001) and IEC 60825-2
Ed. 3.0 (2004) standards for detailed information.
In earlier editions of the IEC 60825 standard the following laser classes and
corresponding power limits were defined for wavelengths of 1310 nm and 1550 nm.

Notes:
1. Corresponding laser warning labels can still be found on equipment manufactured before
publication of the IEC 60825-1 Ed. 1.2 (2001) standard.
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
one second after automatic power reduction takes place, provided that maximum
output and restart conditions are met.
