Essentials for Reliable Fiber Test
Results
To get reliable fiber test results, you must follow proper
cleaning and referencing procedures and, in some cases,
use mandrels during testing.
Cleaning Connectors and Adapters
Always clean and inspect fiber connectors before making
connections. Use fiber optic solvent and optical-grade
wipes or swabs to clean connectors as follows:
Bulkhead Connectors and the Fiber Module's Output
Connector
Note
Use a 2.5 mm foam swab for cleaning the fiber
module's output connector.
1
Touch the tip of a fiber optic solvent pen or swab
soaked in solvent to a lint-free dry wipe or fiber
cleaning card.
2
Touch a new, dry swab to the solvent spot on the wipe
or card.
3
Push the swab into the connector; twist it around 3 to
5 times against the endface, then remove and dispose
of the swab.
4
Dry the connector with a dry swab by twisting it
around in the connector 3 to 5 times.
5
Inspect connectors with a fiber microscope, such as the
Fluke Networks FiberInspector Video Microscope
before making connections.
Fiber Module's Input Connector
1
Remove the connector adapter to expose the
photodiode lens (see Figure 4).
2
Use the method described in steps 1 and 2 above to
dampen a swab with solvent.
3
Twist the damp swab around against the lens 3 to 5
times; then twist a dry swab around against the lens 3
to 5 times.
Connector Adapters and Fiber Adapters
Periodically clean connector adapters and fiber adapters
with a swab and fiber optic solvent. Dry with a dry swab
before use.
