Power Shut Down (APSD) are engineering controls that are also used to limit the
emissions. 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 eyewear or indirect viewing instruments such as
Find-R-Scopes are not considered magnifying lenses or optical instruments).
2. Only authorized, trained personnel shall use optical test equipment during
installation or servicing since this equipment contains semiconductor lasers. (Some
examples of optical test equipment are Optical Time Domain Reflectometers (
OTDR’s), Hand-held Loss Test Sets).
3. 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.
4. 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 Lasers in the U.S.
or outside the U.S., IEC-60825, Part 2 for guidance on the safe use of optical fiber
optic communication systems in the workplace.
