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.

Abstract: Disclosed herein is a ferrule assembly. The ferrule assembly comprises a ferrule having an inner diameter surface. The ferrule assembly also comprises an adhesion promotor coating composition comprising an amine functionality, a glycidyl functionality, a thiol functionality, an oxirane functionality, or any combination thereof and a radical cure initiator. The ferrule assembly may further comprise an inorganic hydrolysable layer on the inner diameter surface. The ferrule assembly may also further comprise an adhesion promotor coating on the inorganic hydrolysable layer of a composition.

Abstract: Aspects and techniques of the present disclosure relate to a cleaning substrate with liquid-filled microcapsules embedded therein. The cleaning substrate may include cleaning swabs, tapes, or textiles that can be used to provide enhanced cleaning of optical fiber end faces. Cleaning is achieved by bringing the liquid-filled microcapsules into contact with a surface of application, such as an end face of an optical fiber connector. When the cleaning substrate is rubbed in contact with the surface of application, liquid burst from the liquid-filled microcapsules of the cleaning substrate to remove foreign matter or contamination, such as oil and dust, from the surface of application.

Abstract: Some example methods of connectorizing an end of an optical cable include providing the ferrule assembly including a ferrule, a stub optical fiber extending rearwardly from the ferrule, and a flange disposed about the ferrule; splicing the stub optical fiber to an optical fiber of the optical cable at a splice location; and overmolding a rear hub portion (e.g., without any protective layers disposed between the rear hub portion and the stub optical fiber and optical fiber of the optical cable) using an adhesive material. The flange may include Nylon 6, 6. Splicing the fibers may include pulling the fibers away from each other during splicing without separating the fibers.
