Fiber optic ceramic ferrule cannot be cleaned properly
If you wet-clean, use a dry lint-free pad to dry the connector off and then inspect it to ensure it is clean. Their tight tolerances and robust structures ensure minimal signal loss at connection points—a critical factor as bandwidth and data. Polishing finalizes the connector endface and cleans the surface, which has a direct impact on optical performance parameters such as insertion loss. The requirement to inspect fiber connectors (and clean if necessary) before connection is strongly recommended in all cases; this includes the first use of new cables and transceivers or any equipment/panels with fiber interfaces. Much of the dirt is silica-based and hard enough to scratch the fiber if sandwiched.
