Some adapters have an anti-reflection coating on the back to
reduce back reflection. This coating is extremely sensitive to
solvents and mechanical abrasion. Extra care is needed when
cleaning these adapters.
When using optical head adapters, periodically inspect the
optical head's front window. Dust and metal particles can be
propelled through the adapter's pinhole while inserting the
connector ferrule into the receptacle. These dirt particles
collect on the head's front window, which can lead to incorrect
results if not removed.
Preferred Procedure
Use the following procedure on most occasions.
1 Clean the adapter by rubbing a new, dry cotton swab over the
surface using a small circular movement.
2 Blow away any remaining lint with compressed air.
Procedure for Stubborn Dirt
Use this procedure when there is greasy dirt on the adapter:
1 Moisten a new cotton swab with isopropyl alcohol.
2 Clean the adapter by rubbing the cotton swab over the
surface using a small circular movement.
3 Take a new, dry soft tissue and remove the alcohol, dissolved
sediment and dust, by rubbing gently over the surface using a
small circular movement.
4 Blow away any remaining lint with compressed air.
Be careful when using pipe cleaners, as the core and the
bristles of the pipe cleaner are hard and can damage the
interface.
Do not use pipe cleaners on optical head adapters, as the hard
core of normal pipe cleaners can damage the bottom of an
adapter.
