Cleaning 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
residue. Inspect connectors after cleaning to confirm that they are clean and
undamaged.
Recommended Equipment
¾
CLETOP or OPTIPOP ferrule cleaner (for specific connector type)
¾
Compressed air (also called “canned air”)
¾
Lint-free wipes moistened with optical-grade (99%) isopropyl alcohol
¾
Bulkhead swabs (for specific connector type)
¾
Optical connector scope with appropriate adaptor
Tips for Optimal Fiber Optic Connector Performance
¾
Do not connect or disconnect optical connectors with optical power present.
¾
Always use compressed air before cleaning the fiber optic connectors and when
cleaning connector end caps.
¾
Always install or leave end caps on connectors when they are not in use.
¾
If you have any degraded signal problems, clean the fiber optic connector.
¾
Advance a clean portion of the ferrule cleaner reel for each cleaning.
¾
Turn off optical power before making or breaking optical connections to avoid
microscopic damage to fiber mating surfaces.
