Abstract
A plastic optical fiber cable with a ferrule in which a plastic sheath of the end side of the optical fiber cable is removed to expose a plastic optical fiber from the end of the optical fiber cable, and the ferrule is secured to the outer periphery of the end side of the optical fiber cable, wherein the ferrule is axially formed as a combination of a plastic cylindrical member for forming the end of the ferrule, and a metal cylindrical member for forming the base end, wherein the plastic cylindrical member is in contact with the enlarged part of the end of the optical fiber core at the inner peripheral surface of the end side to be secured to the end of the optical fiber core, and the metal cylindrical member is contacted under pressure with the outer periphery of the end of the plastic sheath by a stopper projecting from the inner peripheral surface of the metal cylindrical member so as to be fastened to the plastic sheath. Thus, the rigid ferrule can be mounted at the end of the plastic optical fiber cable in a short time and does not damage the core even if a heating cycle is applied thereto.
