Inspection and Cleaning Procedure
Inspection
To inspect and clean the fibers, follow these steps:
1
Ensure the fiber is not "live."
WARNING!
Eye damage may occur if an optical instrument such as a microscope, magnifying
glass, or eye loupe is used to stare at an energized fiber end.
2
Inspect the fiber endface with a fiberscope.
3
If the fiber endface is clean, return to the installation instructions; if the connector is dirty,
proceed to the dry cleaning instructions below.
Dry Cleaning
If you are using cartridge- or pocket-style dry cleaning tools, follow the manufacturer's
directions. If you are using lint-free wipes, follow these steps:
1
Fold the lint-free wipe four to eight times into a square, taking care to avoid touching the
cleaning surface of the wipe.
2
Lightly wipe the fiber tip in the central portion of the lint-free wipe.
Do not scrub the fiber. Excessive rubbing will leave scratches.
3
Repeat the wiping action on another clean section of the wipe or a new wipe.
4
Inspect the connector again with the fiberscope.
5
If the connection is clean, return to the installation steps; if the connector is still dirty,
proceed to the wet cleaning instructions.
Wet Cleaning
Using 99.8% isopropyl alcohol and lint-free wipes, follow these steps to wet clean the fiber:
1
Fold the wipe into a square, about 4 to 8 layers thick.
2
Moisten one section of the lint-free wipe with one drop of 99.8% alcohol, ensuring that a
portion of the wipe remains dry.
3
Lightly wipe the fiber end in the alcohol-moistened portion of the lint-free wipe.
4
Immediately repeat the wiping action on the dry section of the wipe, removing any residual
alcohol.
5
Inspect the fiber endface again, and if necessary, repeat the wet cleaning with another
clean section of the lint-free wipe.
CAUTION!
Do not scrub the fiber. Excessive rubbing will leave scratches.
6
Dry clean any remaining residue, and then inspect the connector again.
