Dry Cleaning
CAUTION!! 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 for the 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
