Cleaning of fiber optic connectors
●Fiber optic cables, assemblies, optical fiber connectors and equipment may only be installed and commissioned by qualified personnel. All local and national safety regulations must be accepted and adhered to. The optical performance (optical insertion loss and return loss) of fiber-optic connectors is easily and adversely affected by contamination and scratching of the fiber end face surfaces. Particles of dust and smears of grease, caused by touching the ferrules end face, or the residue from cleaning agents, can cause increased insertion losses and, in extreme cases, can culminate in loss of signal. During an installation, it is therefore necessary to ensure that ferrule end face surfaces are clean, which means：
◆Only store fiber optic assemblies in their original packaging
Do not remove protective caps until immediately before mating
◆Connectors should never be left lying around without protective caps in place
◆Never touch the end surfaces or make preliminary contact with foreign surfaces
◆Always work very carefully and maintain a clean working environment
●LC connectors tend to be much more prone to contamination and scratching than, for example, robust ODC or Q-ODC connectors on which the ferrules are protected mechanically from physical contact. However, the cleaning of these connectors will require other mechanical solutions.
●All HUBER+SUHNER fiber optic assemblies are 100 % manufactured in an industrial environment and are governed by standards which are implemented and controlled within the factory environment. The fiber optic cable assemblies, as well as the fiber optic systems, are inspected for insertion loss and the cleanliness of the ferrule end face. Factory-terminated fiber optic connectors supplied to the market are cleaned and ready for installation.
●Despite our careful control, contamination of dust or microscopically small parts on the end faces cannot be 100 % excluded.
●HUBER+SUHNER therefore recommends inspecting all connector end surfaces and, if necessary, cleaning them. Information and instruction concerning this topic is given in the last chapter of this document. It is also important that the corresponding opposite side is also inspected and, if necessary, cleaned and ready for mating.
●Disregarding initial installation, field cleaning is however an important process and one that needs to be handled effectively and competently by the installation teams. Ferrules can get dirty during installation work (e.g. through physical contact) and, in such cases, visible inspection is urgently advised. During a network service or expansion, existing fiber optic connections are often disconnected and then get reconnected - here too, visible inspection is advisable prior to reconnection.
