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:
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, Part 2 .
