Dry Cleaning
ATTENTION!
Invisible laser radiation might be emitted from disconnected fibres or connectors. Do
not stare into beams or view directly with optical instruments.
1. Before cleaning the optical connectors on the OMU it is advisable to clean the connector of the
mating cable being attached to the optical port.
An unclean optical connector is often the cause for reduced system performance. A bit of dust or
oil from a finger can easily interfere with, or block light. Fortunately, it is very easy to clean the
connector. Be sure to use the correct procedure for the given connector. When disconnected,
cap the SC/APC connector to keep it clean and prevent scratching the tip of the ferrule.
Use a product specially designed
purpose, such as the Cletop type S Cassette
Cleaner.
2. Begin by dry cleaning the F/O bulkhead connector (shown below is the Fujikura One-Click in use).
IMPORTANT
Always make sure there is a way of inspecting the connector after cleaning. Cleaning can
actually leave the end-face in a worse condition, since alcohol residue is one of the most
difficult contaminants to remove.
3. Remove the protective cap from the
cleaning-head end of the “One Click”
cleaner, lift the protective end-cap on
the fibre connector and offer-up the
end to the fibre connector
