DLC Connectors and Adapter cleaning
Clean exposed connector ferrule by lightly moistening lint-free wipe with fiber optic cleaning solution (or >91% isopro-
pyl alcohol), and by applying medium pressure, first wipe against wet area and then onto dry area to clean potential
residue from end face. Clean connector ferrule inside adapter by inserting lightly moistened cleaning stick with fiber
optic cleaning solution (or >91% isopropyl alcohol) inside the adapter until contact is made with connector on opposite
end. Rotate cleaning stick with medium pressure in one circular motion as it is pulled away from the adapter. Repeat
process using dry cleaning stick.
Caution: Signal strength will be affected if end and sides of ferrule are not thoroughly cleaned. Discard cleaning
sticks after each use. Do not turn cleaning sticks back and forth pressing against connector end face. This may cause
scratches if large contamination is present. Always inspect connector end face for contamination after each cleaning.
Clean adapter by inserting adapter cleaning stick (or fiber adapter sleeve brush) moistened with fiber optic cleaning
solution (or >91% isopropyl alcohol) inside the adapter and gently pull out with twisting motion. Repeat process with a
dry cleaning stick.
Caution: Do not try to clean adapter with a standard pipe cleaner. The sleeve inner diameter of DLC adapters is too
small. Do not try to clean the adapter with cleaning stick if a connector is mounted in one side. Discard cleaning sticks
after each use.
