Below are procedures for “wet” cleaning and “dry” cleaning. For best results, a combination of these cleaning methods is
recommended.

“WET” CLEAN PROCEDURE
Wet the tip of a 2.5mm cleaning swab with isopropyl
alcohol.
Carefullyinsertthewettipoftheswabintotheoptical
port.
Clean out the optical port according to the directions
providedwiththeswabs.
Blow dry the optical port with the compressed air. If
compressed air is not available, allow 2 minutes for
thealcoholtoevaporate.
Inspect the optical port with the fiber optic inspection
probetoensuretheportisclearofobstructions.
If the port is still dirty, another round of cleaning will be
necessary. You may also want to use a combination of “wet”
and“dry”cleaningtoachievebestresults.
“DRY” CLEAN PROCEDURE
Carefully insert a dry 2.5mm cleaning swab or a
2.5mm in-adapter ferrule connector cleaner into the
opticalport.
Clean out the optical port according to the directions
thatcamewiththecleaningaccessories.
