Cleaning!fiber!optic!connectors!

The process described here should not be applied routinely. This procedure should only be

performed in cases where degraded performance of the assembly is noted or there is

evidence of contamination. Excessive cleaning may actually increase the likelihood of fiber
contamination.

Materials used for cleaning fiber-optic devices should be consistent with the function. Wiping

cloths should be made of lint free, non-abrasive materials. Cotton swabs should have a tightly

wrapped tip and be talcum-free. Pure optical grade isopropyl alcohol is the recommended
solvent for cleaning connector tips. For removing dust from receptacles, a canned

compressed gas is recommended.

Cleaning!procedures!

!

!

Remove any accumulated dust or debris from the connector by blowing off the

cylindrical and end-face surfaces of the connector using the compressed gas.

!

!

Use a pad or a wipe saturated with optical-grade isopropyl alcohol to gently wipe the

cylindrical and end-face surfaces.

!

!

Use compressed gas to blow dry the connector surfaces or allow them to air dry.

!

!

Avoid touching the connector surfaces after cleaning. If the connector is not going to be

used, it should be covered with a dust cap to prevent contamination.

Handling!of!connectors!

Although ruggedly constructed, fiber connectors should be handled with care during

insertion. Follow these tips to make secure, long lasting connections:

!

!

After removing the protective cap, make sure the fiber end remains clean and moisture
free.

!

!

Insert the connector into the fitting by grasping the rigid plastic fitting directly behind the
fiber output shroud. The connection is fully seated when you hear it snap (click) into

place.

!

!

Never attempt to insert the connector by gripping the white or green flexible shroud.

This may cause the fiber to kink in the jacket, introducing unwanted noise to the line.
