Chapter 4: Clean Fiber Endfaces
How to Use Wipes, Swabs, and Solvent
79
To Clean the Optical Connectors on the Modules
To clean the optical connectors on the modules, first use the
procedure given under “To Clean Bulkhead Connectors”.
If a connector is very dirty or the procedure above does not make
it clean, use this procedure:
1
Unscrew the adapter on the connector.
2
Clean the ferrule or photodiode lens with a dry, optical-grade
wipe made for fiber optic connectors.
3
Use a video probe to inspect the connector. If necessary, clean
and inspect the connector again.
4
If the connector stays dirty, use a wipe that is moist with
optical-grade solvent to clean the endface. Dry the ferrule or
lens with a dry wipe.
To Clean Fiber Adapters
At regular intervals, clean fiber adapters with a swab and fiber
optic solvent. Dry with a dry swab.
To Clean Connector Ends
1
Use a video probe to inspect the connector. If it is dirty,
continue to step 2.
2
Touch the tip of a fiber optic solvent pen or swab soaked in
solvent to a lint-free dry wipe or fiber cleaning card.
3
Rub the connector end-face across the solvent spot, then back
and forth once across the dry area of the wipe or card.
Typically, one or two short strokes (~1 cm or ~0.4 in) are
sufficient to dry the endface.
4
Use a video probe to inspect the connector. If necessary, clean
and inspect the connector again.
