With the help of this card you are able to inspect the shape of
laser light emitted. The invisible laser beam is projected onto
the sensor card. The light beam's infrared wavelengths are
refleted at visible wavelengths, so becoming visible to the
normal eye as a round spot.
Take care never to look into the end of a fiber or any other
optical component, when they are in use. This is because the
laser can seriously damage your eyes.
Preserving Connectors
Listed below are some hints on how best to keep your
connectors in the best possible condition.
Making Connections
Before you make any connection you must ensure that all cables
and connectors are clean. If they are dirty, use the appropriate
cleaning procedure.
When inserting the ferrule of a patchcord into a connector or an
adapter, make sure that the fiber end does not touch the outside
of the mating connector or adapter. Otherwise you will rub the
fiber end against an unsuitable surface, producing scratches
and dirt deposits on the surface of your fiber.
Dust Caps and Shutter Caps
Be careful when replacing dust caps after use. Do not press the
bottom of the cap onto the fiber as any dust in the cap can
scratch or dirty your fiber surface.
When you have finished cleaning, put the dust cap back on, or
close the shutter cap if the equipment is not going to be used
immediately.
Always keep the caps on the equipment when it is not in use.
All of Agilent Technologies' lightwave instruments and
accessories are shipped with either laser shutter caps or dust
caps. If you need additional or replacement dust caps, contact
your nearest Agilent Technologies Sales/Service Office.
