Plastic optical fiber cord with ferrule.

摘要

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