Which Cleaning Procedure
should I use ?
Light dirt If you just want to clean away light dirt, observe the following
procedure for all devices:
• Use compressed air to blow away large particles.
• Clean the device with a dry cotton swab.
• Use compressed air to blow away any remaining filament left by the
swab.
Heavy dirt If the above procedure is not enough to clean your instrument, follow
one of the procedures below. Please consult “Cleaning Instructions
for this Device” on page 89 for the procedure relevant for this
instrument.
If you are unsure of how sensitive your device is to cleaning, please
contact the manufacturer or your sales distributor
How to clean connectors
Cleaning connectors 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 condition of the
surface of your connector and to check it after cleaning, you need a
microscope.
In the case of scratches, or of dust that has been burnt onto the surface
of the connector, you may have no option but to polish the connector.
This depends on the degree of dirtiness, or the depth of the scratches.
This is a difficult procedure and should only be performed by a skilled
person, and as a last resort as it wears out your connector.
W A R N I N G Never look into the end of an optical cable that is connected to an
active source.
To assess the projection of the emitted light beam you can use an
infrared sensor card. Hold the card approximately 5 cm from the
output of the connector. The invisible emitted light is projected onto
the card and becomes visible as a small circular spot.
