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 Keysight 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 Keysight Technologies Sales/Service
Office.
Immersion Oil and Other Index Matching Compounds Wherever
possible, do not use immersion oil or other index matching
compounds with your device. They are liable to impair and
dirty the surface of the device. In addition, the
characteristics of your device can be changed and your
measurement results affected.
