The one constant that holds true to all fiber optic connectors is the importance of the surface quality of the fiber optic connector end-face. Scratches, embedded dust particles and residues in the contact zone of a mated connector pair will disrupt the path through which the light travels, as it crosses out of the transmitting connector’s end-face into the receiving connector’s end-face. The best way to get optimal performance from fiber optic connections is to proactively inspect and clean both ends of a mated connector pair.
