How to clean connector adapters Cleaning Information

To assess the projection of the emitted light beam you can use an
infrared sensor card. Hold the card approximately 5 cm from the
output of the connector. The invisible emitted light is projected onto
the card and becomes visible as a small circular spot.
Preferred Procedure Use the following procedure on most occasions.
1 Clean the connector 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 connector:
1 Moisten a new cotton swab with isopropyl alcohol.
2 Clean the connector 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.
An 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 adapters
CAUTION 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.
