Eye Safety Guidelines
l Do not look into unterminated ports or at fibers that connect to unknown sources.
Laser infrared radiation, which is not visible to the naked eye, can emit from
unterminated receptacles of an optical module or an optical fiber connector if the
associated fiber-optic transmitter is powered.
l Do not examine unterminated optical ports with optical instruments.
l If you view the laser output with certain optical instruments, for example, eye loupes,
magnifiers, and microscopes, within a distance of 100 mm, an eye hazard can occur.
Before you use an optical instrument to inspect a connector, use a power meter to
confirm that the fiber is not transmitting optical energy.
l Laser radiation can emit from optical testing equipment into the optical fibers. Take the
necessary precautions.
l Cap unused ports and connectors to prevent accidental exposure to laser emission.
l Remove the protective caps or blind plugs from the client and network output channel
(Tx) connectors only when necessary for installation and maintenance purposes.
Failure to do so can cause permanent eye or skin damage and can also lead to
blindness.
l Avoid direct exposure to the beam.
l Do not wear contact lenses while working with optical fiber cables.
l Do not connect or disconnect fiber-optic cables at eye level.
LASERRADIATIONWARNING
l Use of controls or adjustments or performance of procedures
other than those specified in the HD documentation may result
in hazardous radiation exposure.
l There is exposure to hazardous laser radiation when the
protective housing is open and interlocks are defeated. Do not
remove the covers. There are no serviceable parts inside the
device.
l Even for extremely short durations of exposing optical power
levels, permanent eye damage or blindness can result.
l High intensity and invisible light is emitted from the optical
output receptacles of amplifier modules. Ensure that all
connectors are terminated properly before setting the
amplifier's Admin state to "In Service."
