Cleaning Fiber Optic Connectors
Note:
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 their 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
To clean a fiber connection
1.
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.
2.
Use a pad or a wipe saturated with optical-grade isopropyl alcohol to gently wipe the
cylindrical and end-face surfaces.
3.
Use compressed gas to blow dry the connector surfaces or allow them to air dry.
4.
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 APC Connectors
Although ruggedly constructed, fiber connectors must be handled with care when inserting
the SC/APC connector into the MEM. Follow these tips for making secure, long lasting
connections:
y
After removing the protective cap, make sure the fiber end remains clean and moisture
free.
y
Insert the connector into the bulkhead 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.
y
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.
