Appendix A: Laser Safety Guidelines
Precautions for Enclosed Systems
In its normal operating mode, an optical fiber communication system is
totally enclosed and presents no risk of eye injury. However, if the fiber
optic cables that interconnect various components of an optical fiber
disconnect or break, you may be exposed to laser emissions. Also,
technicians may be exposed to laser emissions during installation and
servicing.
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.
Under normal operating conditions, optical fiber telecommunication
systems are completely enclosed; nonetheless, observe the following
precautions:
1. Do not stare into optical connectors or broken fibers.
2. Ensure technicians have satisfactorily completed an approved
training course before performing installation or maintenance.
3. 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 these practices:
1. Avoid exposing the eye to emissions from unterminated, energized
optical connectors at close distances.
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.
CAUTION
Only authorized, trained personnel shall be permitted to do
service, maintenance, and restoration.
