◦ Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.
◦ Clean the connectors regularly; the required frequency of cleaning depends upon the environment.
In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry
cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.
◦ Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other
contamination.
• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under
a microscope to determine if damage has occurred.
• To minimize the chance of damaging transceivers when installing them, slide them gently into their
switch slots and never force them all the way into the slots. If the transceiver stops part way into the
slot, it might be upside down and you should remove the transceiver before turning it over and reinstalling
it. If positioned correctly, the transceiver will slide all the way into the slot and click when fully installed.
Statement 1051
—
Laser Radiation
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments.
Warning
Statement 1053
—
Class 1M Laser Radiation
Class 1M laser radiation when open. Do not view directly with optical instruments.

—
Class I and Class 1M Laser
Class I (CDRH) and Class 1M (IEC) laser products.
Warning
Statement 1056
—
Unterminated Fiber Cable
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not
view directly with optical instruments. Viewing the laser output with certain optical instruments (for
example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard.
Warning
Maintaining Transceivers and Optical Cables
Transceivers and fiber-optic cables must be kept clean and dust free to maintain high signal accuracy and
prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should be
below 0.35 dB.
Consider the following maintenance guidelines:
• Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is
connected to the grounded chassis.
