Cleaning and Inspecting Fibers and Ports
Step 12 Inspect the connector again using the video scope. If the connector is still dirty
after a second dry cleaning, clean it with a wet cleaning technique, followed
immediately with another dry cleaning, to ensure that no residue is left on the
endface.
To perform a wet cleaning, gently wipe the ferrules and endface surfaces of the
connector plugs using a pad saturated with optical-grade isopropyl alcohol.
Make sure that the pad makes full contact with the endface surfaces.
Dry the connector surfaces with canned, oil-free compressed air or let them air
dry for 5 seconds.
Wet cleaning is not recommended for bulkheads and receptacles. Damage to the
equipment can occur.
Step 13 Inspect the connector again. If the contaminant still cannot be removed, repeat
the cleaning procedure using a fresh surface on the pad.
Note
Do not touch the connector surfaces after cleaning.
If the endface surface of the connector remains dirty after repeated
cleaning, replace the fiber-optic cable.
Step 14 Attach the fiber connector plug to the corresponding receptacle. If the cleaned
connectors are not going to be used right away, cover them with protective
caps/plugs to prevent contamination.
Never use alcohol or wet cleaning without a way to ensure that it does not leave
residue on the endface. Alcohol residue can cause equipment damage.
Cleaning and Inspecting Connector Receptacles
The procedure described above for fiber-optic connector plugs should not be applied
routinely to fiber-optic connector receptacles. The receptacles in the modules have been
cleaned and connected by the manufacturer.
The operation of the system should be free of errors if the customer provides clean
connector plugs on the application side.
Note
Do not clean the inside of the receptacles unless you suspect light power
is reduced due to contamination.
CAUTION
Only authorized personnel are allowed to perform this procedure.
