be inspected first, cleaned if necessary, then mated This applies to plugs with a single fibre cylindrical ferrule and a multi-fibre rectangular ferrule A Pl u g c o n n e c t o r i n s i d e a d a p t o rs Ferrule end-faces inside of connector plugs inside ports and receptacles should also be inspected first, cleaned if necessary, then inserted into the plugs The receptacle connectors are widely used as interface in communication equipment, measuring instruments, transceivers, etc A Ad a p t o r fo r a c y l i n d ri c a l fe rru l e p l u g An adaptor for a cylindrical ferrule plug usually contains an alignment sleeve Although there is no end-face in the adaptor, the inside of the sleeve should be cleaned Contamination inside the sleeve may spread onto the plug end-face during mating Therefore the cleaning of the inside of the sleeve is important to maintain the cleanliness of plug end-faces A Ti m i n g o f th e cl e a n i n g There is a possibility that contamination adheres to the end-face at any time Therefore before every connection, inspection and if necessary cleaning of the plug end-face should be performed After every cleaning, an inspection of the plug end-face should follow to ensure a clean end-face If installing a fibre optic patch cord in a network, even a brand new one (right out of the package), the plug end-faces on both ends of the patch cord should be cleaned before mating if no inspection has been carried out It is probable that it was clean when tested at the manufacturing plant but it could become contaminated before the package is opened to install the fibre optic cord A Ad d i t i o n a l i n fo rm a t i o n a) Isopropyl alcohol (IPA) and some liquid cleaners will absorb moisture from its surroundings, including air Therefore, a container of IPA left open to the air can easily become diluted and contaminated Contaminated IPA can leave a residue on the end-face of the plug contributing to the reduced performance of the fibre optic link IPA with a volume fraction of 95% or higher should be used b) Not all materials are suitable for cleaning optical plugs Materials not specifically designed for optical cleaning (e.g cotton swabs, some types of tissue paper, some types of foam) may contain contaminants that will remain on the fibre surface, or break down and leave material remnants on the plug c) Repackaging of wipes or swabs into one's own containers may contaminate the cleaning products Cleaning wipes or swabs removed from packaging and left “out” before use can pick-up contaminates from the air or handling d) If in doubt about the cleanliness/effectiveness of the fibre optic cleaning products, try the “do no harm” test e) Take a clean plug (verified clean by inspection with a microscope) Copyright
