However, technicians removing or replacing laser circuit packs
should not stare or look directly into the optical port with optical
instruments or magnifying lenses. (Normal eye wear or indirect
viewing instruments, such as a Find-R-Scopes, are not considered
magnifying lenses or optical instruments.)
•
Only authorized, trained personnel shall use the optical test
equipment during installation or servicing since this equipment
contains semiconductor lasers. (Some examples of optical test
equipment are Optical Time Domain Reflectometers [OTDRs]
and Hand-Held Loss Test Sets.)
•
Under no circumstances shall any personnel scan a fiber with an
optical test set without verifying that all laser sources on the fiber
are turned off.
•
All unauthorized personnel shall be excluded from the immediate
area of the optical fiber telecommunication systems during
installation and service.
Consult ANSI Z136.2, American National Standard for Safe Use of
Optical Fiber Communication Systems Utilizing Laser Diodes and
LED Sources in the United States or outside the United States,
IEC-60825, Part 2 for guidance on the safe use of optical fiber optic
communication systems in the workplace.
