CLEANING INSTRUCTIONS
In order to maintain the performance of optical interconnections, fibre optic connectors must be cleaned
before mating. A single-mode fibre’s core diameter is only 8-9
μ
m, hence dust particles anywhere from 9
μ
m
down to 1
μ
m in diameter can significantly decrease the system performance due to unwanted – but
avoidable - optical loss!
For cleaning, only lens-grade, lint-free tissue (e.g. Kimwipes), saturated with 99.8+% pure, anhydrous
Isopropyl Alcohol, shall be used.
Vistek recommends the use of pre-saturated wipes. One sachet, containing a pre-saturated wipe, can be
found packed with each board.
Cleaning Technique:
Note that pre-saturated wipes dry out very quickly and they should be used only once.
1.
Place the connector ferrule in the wipe and press the wipe firmly against the sides of the ferrule.
Rotate the ferrule several times to remove possible contamination from the ferrule sides.
2.
Now press a clean part of the wipe against the end of the connector ferrule. Scape the end of the
connector until it squeaks.
3.
Mate the connector immediately!
Remember these basic rules when handling fibre optic connectors:
Do’s
[
Always clean the connectors before mating.
[
Mate the connector immediately.
[
Cover unused connectors with dust protection caps.
Don’ts
x
Never touch the end face of a connector.
x
Do not let the connector lie around and collect dust before mating.
