Laser Safety Instructions
Zhone equipment and associated optical test sets use laser sources that emit
light energy into fiber cables. This energy is within the red (visible) and
infrared (invisible) regions of the electromagnetic spectrum.
Laser products are subject to federal and state or provincial regulations, and
local practices. Regulation 21 CFR 1040 of the U.S. Bureau of Radiological
Health requires manufacturers to certify each laser product as Class I, II, III,
or IV, depending upon the characteristics of the laser radiation emitted. In
terms of health and safety, Class I products present the least hazard (none at
all), while Class IV products present the greatest hazard.
Although Zhone optical products have a Class I certification, hazardous
exposure to laser radiation can occur when fibers connecting system
components are disconnected or broken.
Certain procedures carried out during testing require the handling of optical
fibers without dust caps and therefore increase the risk of exposure. Exposure
to either visible or invisible laser light can damage your eyes under certain
conditions.
Read and observe the following precautions to decrease the risk of exposure
to laser radiation.
WARNING!
Risk of eye damage. At all times, when handling
optical fibers, follow the safety procedures recommended by your
company.
WARNING!
Avoid direct exposure to fiber ends or optical
connector ends. Laser radiation may be present and can damage
your eyes.
WARNING!
Never look into an active optical fiber or an optical
fiber connector opening of an active or powered-up unit.
Note: When working with optical fibers, take these precautions:
•
Wear safety glasses when installing optical fibers.
•
Clean hands after handling optical fibers. Small pieces of glass are not
always visible and can cause eye damage. Get medical assistance
immediately for any glass that comes into eye contact.
