Procedure for Stubborn Dirt
Use this procedure particularly when there is greasy dirt on the adapter:
1
Clean the adapter by pushing and pulling a new, dry pipe-cleaner into
the opening. Rotate the pipe-cleaner slowly as you do this.
Be careful when using pipe-cleaners, as the core and the bristles of the
pipe-cleaner are hard and can damage the adapter.
2
Clean the adapter by rubbing a new, dry cotton-swab over the surface
using a small circular movement.
3
Blow away any remaining lint with compressed air.
You should only clean instruments with a fixed connector interface when it
is absolutely necessary. This is because it is difficult to remove any used
alcohol or filaments from the input of the optical block.
It is important, therefore, to keep dust caps on the equipment at all times,
except when your optical device is in use.
If you do discover filaments or particles, the only way to clean a fixed
connector interface and the input of the optical block is to use compressed
air.
If there are fluids or fat in the connector, please refer the instrument to the
skilled personnel of Keysight's service team.
Only use clean, dry compressed air. Make sure that the air is free of dust,
water, and oil. If the air that you use is not clean and dry, this can lead to
filmy deposits or scratches on the surface of your connector interface.
This will degrade the performance of your transmission system.
Never try to open the instrument and clean the optical block by yourself,
because it is easy to scratch optical components, and cause them to be
misaligned.
