How to clean instruments with an optical glass plate Cleaning Instructions
Agilent 8163A/B, 8164A/B, and 8166A/B User’s Guide, Fourth Edition 423
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.
CAUTION 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 be misaligned.
How to clean instruments with
an optical glass plate
Some instruments, for example, the optical heads from Agilent
Technologies have an optical glass plate to protect the sensor. Clean
this glass plate in the same way as optical lenses (see “How to clean
lenses” on page 422).
How to clean instruments with a
physical contact interface
Remove any connector interfaces from the optical output of the
instrument before you start the cleaning procedure.
Cleaning interfaces is difficult as the core diameter of a single-mode
fiber is only about 9 µm. 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.
