Unlike some other laser designs, semiconductor lasers have a highly divergent beam that decreases
rapidly with distance. The greater the distance, the less energy will enter the eye, and the less potential
risk for eye injury.
WARNING!
Eye damage may occur if an optical instrument such as a microscope, magnifying glass, or eye loupe is
used to stare at the energized fiber end.
Under normal operating conditions, optical fiber telecommunication systems are completely enclosed;
nonetheless, observe the following precautions:
•
Do not stare into optical connectors or broken fibers.
•
Ensure technicians have satisfactorily completed an approved training course before performing
installation or maintenance.
•
Ensure there are appropriate warning labels near the optical ports of the modules.
Precautions for Unenclosed Systems
During service, maintenance, or restoration, an optical fiber telecommunication system is considered
unenclosed. Under these conditions, follow the practices described below.
CAUTION!
Only authorized, trained personnel shall be permitted to do service, maintenance, and restoration.
1.
Avoid exposing the eye to emissions from unterminated, energized optical connectors at close
distances.
2.
Ensure that only authorized, trained personnel use optical test equipment during installation or
servicing.
3.
Turn off all laser sources before scanning a fiber with an optical test set.
4.
Keep all unauthorized personnel away from the immediate area of the optical fiber systems during
installation and service.
For guidance on the safe use of optical fiber communication systems in the workplace, consult
ANSI
Z136.2, American National Standard for Safe Use of Lasers
in the U.S. or outside the U.S.,
IEC-60825,
