Abstract: The present disclosure relates to a thin coated optical fiber that enables connector assembly without stripping the optical fiber. In particular, the thin coating comprises a hard coating, a dye concentrate, and an adhesion promoter. The formulation of the coating promotes adhesion to a glass cladding of the optical fiber and to a ferrule bore (into which the optical fiber is inserted) by not causing silane decomposition of the coating. Moreover, the coating is colored to enable, among other things, fiber identification within a connector. The thin coated optical fibers exhibit good mechanical and optical performance properties as discussed herein.
