Cleaning Connectors
filtered, dry, compressed air. Aim the compressed air at a shallow angle to the
fiber end face.
Nitrogen gas or compressed dust remover can al so be used.
CAUTION Do not shake, tip, or invert compressed air canisters, because this releases
particles in the can into the air. Refer to i nstructions provided on the
compressed air canister.
7As soon as the connector is dry, connect or cover it for later use.
If the performance, after the initial cleaning, seems poor try cleaning the con-
nector again. Often a second cleaning will restore proper performance. The
second cleaning should be more arduous with a scrubbing action.
To clean an adapter
The fiber-optic input and output connectors on many Agilent Technologies
instruments employ a universal adap ter such as those shown in the following
picture. These adapters allow you to connect the instrument to different types
of fiber-optic cables.
Figure 1-7. Universal adapters.
1Apply isopropyl alcohol to a clean foam swab.
Cotton swabs can be used as long as no cotton fibers remain after cleaning. Th e
foam swabs listed in this section’s introduction are small enough to fit into
adapters.
Although foam swabs can leave filmy deposits, these deposits are very thin, and
the risk of other contamination buildup on the inside o f adapters greatly out-
weighs the risk of contamination by foam swabs.
2Clean the adapter with the foam swab.
3Dry the inside of the adapter with a clean, dry, foam swab.
4Blow through the adapter using filte red, dry, compressed air.
Nitrogen gas or compressed dust remover can also be used. Do not shake, tip,
or invert compressed air canisters, because this releases particles in the can
into the air. Refer to instructions provided on the compressed air canister.
