Abstract
An optical fiber-fixing structure of a ferrule is provided. The ferrule is fitted on an optical fiber having a conductor exposed from a sheath by an end processing, so that the ferrule is bonded and fixed to the optical fiber. The ferrule includes a larger inner-diameter and a smaller inner-diameter receiving portion for respectively receiving the sheath and the conductor, and the receiving portions extend continuously through the ferrule from one end to the other end. Grooves and protuberances are formed at the larger inner-diameter receiving portion. The protuberances provide a reduced inner diameter, being defined by distal ends of the protuberances, which is smaller than that of the sheath of the optical fiber, so that the sheath is provisionally fixed relative to the receiving portion in a press-fitted condition.
