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 99 %-pure isopropyl alcohol 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 Dip the tip of a foam swab in alcohol; then touch the
swab to a dry wipe.
2 Touch a new, dry swab to the alcohol spot on the
wipe. Push the swab into the connector; twist it
around 3 to 5 times against the endface, then
remove and dispose of the swab.
3 Dry the connector with a dry swab by twisting it
around in the connector 3 to 5 times.
4 Inspect connectors with a fiber microscope, such as
the Fluke Networks FiberInspector Video Microscope
before making connections.
Fiber Module's Input Connector
Note
Typically, the input connector requires cleaning
only if it has been touched.
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 alcohol.
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.
