Failure of the component or failure of the whole system can be caused by any contamination in the fiber connection. An important component in fiber connection is Fiber optic connector. As we know, end-surface treatment is required by fiber optic cables for proper light transmission. For almost all glass-based fibers, Polishing and fiber polishing pad is an essential step with diameters and cladding larger than 200 microns. Polishing is also needed by all fiber optic connectors.
