Care and Cleaning of Optical Connectors 
 
 
CAUTION: 
Proper operation of this equipment requires clean optical fibers. Dirty 
fibers will adversely affect performance. Proper cleaning is imperative.
 
The proper procedure for cleaning optical connectors depends on the connector type. 
The following describes general instructions for fiber-optic cleaning. Use your 
company's established procedures, if any, but also consider the following. 
Cleaning fiber-optic connectors can help prevent interconnect problems and aid 
system performance. When optical connectors are disconnected or reconnected, the 
fiber surface can become dirty or scratched, reducing system performance. 
Inspect connectors prior to mating, clean as needed, and then remove all residues. 
Inspect connectors after cleaning to confirm that they are clean and undamaged. 
 
Recommended Equipment 
 
CLETOP or OPTIPOP ferrule cleaner (CLETOP Type A for SC, Type B for LC) 
 
Compressed air (also called “canned air”) 
 
Lint-free wipes moistened with optical-grade (99%) isopropyl alcohol 
 
Bulkhead swabs for LC or SC type connectors (choose appropriate type) 
 
Optical connector scope 
 
Tips for Optimal Fiber-Optic Connector Performance 
 
Do not connect or disconnect optical connectors with optical power present. 
 
Always use compressed air before cleaning the fiber-optic connectors and when 
cleaning connector end caps. 
 
Always install or leave end caps on connectors when they are not in use. 
 
If you have any degraded signal problems, clean the fiber-optic connector. 
 
Advance a clean portion of the ferrule cleaner reel for each cleaning. 
 
Turn off optical power before making or breaking optical connections to avoid 
microscopic damage to fiber mating surfaces.
