What should be done to all connectors prior to plugging them into any components or test equipment?

• A. Cleaning
• B. Polishing
• C. Inspecting under magnification
• D. Calibrating equipment

Answer: (A)

Contamination-free connections are essential for preserving signal quality. Before plugging any fiber-optic connector into equipment, you should clean the end-face and ferrule surfaces to remove dust, oils, and residues. Any little speck or film on the mating surface can scatter light, increase insertion loss, and raise return loss, degrading performance and potentially stressing equipment over time. The reliable approach is to use a lint-free fiber-optic cleaner or isopropyl alcohol on a lint-free wipe, following proper cleaning procedures, and to let the surface dry completely before mating. Hold the connector by the body and avoid touching the end-face to prevent recontamination. Polishing isn’t a routine pre-use step; it’s used for re-terminating or refurbishing fiber ends. Visual inspection under magnification helps confirm cleanliness, but cleaning should come first to remove contaminants. Calibrating equipment is about the instruments’ accuracy and doesn’t address the cleanliness of the connectors themselves.
