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.
Keep the caps on the equipment always 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
Where it is 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.
Use a dry and very soft cotton tissue to clean the instrument housing
and the keypad. Do not open the instruments as there is a danger of
electric shock, or electrostatic discharge. Opening the instrument can
