Troubleshooting and Maintenance
We suggest these protective coverings should be kept on the
equipment at all times, except when your optical device is in
use. Be careful when replacing dust caps after use. Do not
press the bottom of the cap onto the fiber too hard, as any
dust in the cap can scratch or pollute your fiber surface.
If you need further dust caps, please contact your nearest
Agilent Technologies sales office.
Isopropyl alcohol This solvent is usually available from any
local pharmaceutical supplier or chemist's shop.
If you use isopropyl alcohol to clean your optical device, do
not immediately dry the surface with compressed air (except
when you are cleaning very sensitive optical devices). This is
because the dust and the dirt is solved and will leave behind
filmy deposits after the alcohol is evaporated. You should
therefore first remove the alcohol and the dust with a soft
tissue, and then use compressed air to blow away any
remaining filaments.
If possible avoid using denatured alcohol containing
additives. Instead, apply alcohol used for medical purposes.
Never drink this alcohol, as it may seriously damage to your
health.
Do not use any other solvents, as some may damage plastic
materials and claddings. Acetone, for example, will dissolve
the epoxy used with fiber optic connectors. To avoid damage,
only use isopropyl alcohol.
Cotton swabs We recommend that you use swabs such as Q-
tips or other cotton swabs normally available from local
distributors of medical and hygiene products (for example, a
supermarket or a chemist's shop). You may be able to obtain
various sizes of swab. If this is the case, select the smallest
size for your smallest devices.
Ensure that you use natural cotton swabs. Foam swabs will
often leave behind filmy deposits after cleaning.
Use care when cleaning, and avoid pressing too hard onto
your optical device with the swab. Too much pressure may
scratch the surface, and could cause your device to become
misaligned.
It is advisable to rub gently over the surface using only a
small circular movement.
