To clean a non-lensed connector
C A U T I O N
Do not use any type of foam swab to clean optical fiber ends. Foam swabs can leave filmy deposits
on fiber ends that can degrade performance.
1 Apply pure isopropyl alcohol to a clean lint-free cotton swab or lens paper.
Cotton swabs can be used as long as no cotton fibers remain on the fiber end after cleaning.
2 Clean the ferrules and other parts of the connector while avoiding the end of the fiber.
3 Apply isopropyl alcohol to a new clean lint-free cotton swab or lens paper.
4 Clean the fiber end with the swab or lens paper.
Do not scrub during this initial cleaning because grit can be caught in the swab and become a
gouging element.
5 Immediately dry the fiber end with a clean, dry, lint-free cotton swab or lens paper.
6 Blow across the connector end face from a distance of 6 to 8 inches using filtered, dry,
compressed air. Aim the compressed air at a shallow angle to the fiber end face.
Nitrogen gas or compressed dust remover can also be used.
C A U T I O N
Do not shake, tip, or invert compressed air canisters, because this releases particles in the can into
the air. Refer to instructions provided on the compressed air canister.
7 As soon as the connector is dry, connect or cover it for later use.
If the performance, after the initial cleaning, seems poor try cleaning the connector again. Often
a second cleaning will restore proper performance. The second cleaning should be more arduous
with a scrubbing action.
