E.4 Preserving Connectors
Listed below are some hints on how best to keep your connectors in 
the best possible condition.

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 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
