Alternative procedure
A better, more gentle, but more expensive
cleaning procedure is to use an ultrasonic bath with isopropyl
alcohol.
1 Hold the tip of the connector in the bath for at least three
minutes.
2 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.
3 Blow away any remaining lint with compressed air.
How to clean connector interfaces
Preferred procedure
Use the following procedure on most
occasions.
1 Clean the interface by pushing and pulling a new, dry pipe
cleaner into the opening. Rotate the pipe cleaner slowly as
you do this.
2 Blow away any remaining lint with compressed air.
Procedure for stubborn dirt
Use this procedure when there is
greasy dirt on the interface.
1 Moisten a new pipe cleaner with isopropyl alcohol.
2 Clean the interface by pushing and pulling the pipe cleaner
into the opening. Rotate the pipe cleaner slowly as you do
this.
3 Moisten a new cotton swab with isopropyl alcohol.
4 Using a new, dry pipe cleaner, remove the alcohol, any
dissolved sediment and dust.
5 Blow away any remaining lint with compressed air.
How to clean bare fiber adapters
Bare fiber adapters are difficult to clean. Protect from dust
unless they are in use.
Be careful when using pipe cleaners, as the core and the bristles of
the pipe cleaner are hard and can damage the interface.
