Maintenance

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

• 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
