Despite industry best practice of inspecting and cleaning fiber optic endfaces, contaminated connections remain the number one cause of fiber related problems and test failures in data centers, campus and other enterprise or telecom networking environments.

Network performance is only as good as the weakest link, and the weakest link is wherever a fiberendface is exposed – whether at a patch panel, equipment port or at the end of a patch cord or jumper.
