Cleaning Connector Receptacles
Wet Cleaning Technique Using Lint-Free Swabs
This cleaning method is for advanced users only.
l Improper cleaning can cause damage to the equipment. Isopropyl
alcohol should be removed completely from the connector or
adapter. Residual liquid alcohol can act as a transport
mechanism for loose dirt on the end face. If the alcohol is allowed
to evaporate slowly off the ferrule, it can leave residual material
on the cladding and fiber core. This is extremely difficult to clean
off without another wet cleaning, which is usually more difficult to
remove than the original contaminant. Liquid alcohol can also
remain in small crevices or cavities, where it can re-emerge
during fiber connection.
l On female multi-fiber connectors, ensure that no alcohol gets into
the guide pin holes. The alcohol may come out during mating and
could contaminate your connection.
l Do not use wet cleaning on E-2000 or F-3000 connectors
because the connector can trap the alcohol and re-contaminate
the connector.
1. Verify that you are properly grounded with an anti-static wrist strap or heel strap
connected to the grounded ESDjack.
2. Remove protective end cap and store it in a small resealable container.
3. Inspect the connector with a hand-held fiber scope or video scope (Inspecting Fiber-
optic Connector and Receptacle End Faces).
4. If the dry cleaning procedure did not remove the dirt from the fiber end face, place one
drop of 99% alcohol to lightly moisten a new lint-free swab. Do not oversaturate the
swab.
Have a dry lint-free swab available for drying immediately after the
cleaning. Make sure that drying swab stays clean.
5. Lightly press and turn the dampened swab to clean the ferrule face.
6. Immediately after cleaning, lightly press and turn the second swab (dry) to dry any
remaining alcohol from the ferrule face.
7. Properly dispose of the wet and dry swab. Never reuse a swab.
8. Inspect the connector again.
