Fiber optic maintenance and optical connections
This section describes how to clean the optical connectors and receptacles
used with Zhone Technologies equipment. These processes should be applied
to optical components only in instances where degraded performance is
evidence that the connection is contaminated.

Laser radiation
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.
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.
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.
During service, maintenance, repair, or removal of cables or equipment,
follow these rules:
•
Avoid direct exposure to fiber ends or optical connector ends. Laser
radiation may be present and can damage your eyes.
