Abstract: Disclosed herein are devices and methods for cleaning, verifying cleaning, and coating a ferrule end face in a single housing thereby preventing contamination of the ferrule end face and associated optical fiber end face. Also disclosed herein is a fiber optic assembly including a ferrule; an optical fiber extending through the ferrule to an end face of the ferrule; and a coating on the end face of the ferrule protecting the optical fiber. The coating is prepared by curing a vinyl-terminated polydimethylsiloxane with a crosslinker in the presence of a catalyst.
