4 Blow away any remaining lint with compressed air.
You should only clean instruments with a fixed connector
interface when it is absolutely necessary. This is because it is
difficult to remove any used alcohol or filaments from the input
of the optical block.
It is important, therefore, to keep dust caps on the equipment at
all times, except when your optical device is in use.
If you do discover filaments or particles, the only way to clean a
fixed connector interface and the input of the optical block is to
use compressed air.
If there are fluids or fat in the connector, please refer the
instrument to the skilled personnel of Agilent's service team.
Both the surface and the jacket of the attached connector

should be completely dry and clean.
Only use clean, dry compressed air. Make sure that the air is
free of dust, water, and oil. If the air that you use is not clean
and dry, this can lead to filmy deposits or scratches on the
surface of your connector interface. This will degrade the
performance of your transmission system.
Never try to open the instrument and clean the optical block
by yourself, because it is easy to scratch optical components,
and cause them to become misaligned.
Remove any connector interfaces from the optical output of the
instrument before you begin the cleaning procedure.
Cleaning interfaces is difficult as the core diameter of a single
mode fiber is only about 9 mm. This generally means you cannot
see streaks or scratches on the surface. To be certain of the
degree of pollution on the surface of your interface and to check
whether it has been removed after cleaning, you need a
microscope.
Never look into an optical output, because this can seriously
damage your eyesight.
