OPTICAL CONNECTOR AND END-FACE GRINDING METHOD THEREOF

摘要

PURPOSE: To easily and surely obtain a desired contact surface angle in an optical connector axial center without using a special ferrule by permitting the tip of the ferrule to be inclined at the angleθlarger than the angleθ' so as to provide a sphere surface-ground dome in order to obtain the desired angleθ' to the optical fiber axial center of a normal on a contact surface. CONSTITUTION: An optical connector 20 consists of the ferrule 22 and an optical fiber fixed inside the through-hole of the ferrule 22. 6 is the angle obtained by the normal at the center P of the domeθand the axial center of the optical connector 20 and also the one obtained by the base surface N of the dome Q and a plane being orthogonal with the axial center of the optical connector. When the radius of the dome Q is R and the center P on the dome Q is eccentric by distance S from the axial center of the ferrule 22, the targeting normal angleθ' is obtained at a point O in the axial center when the inclination angleθat the time of grinding is obtained largely by correcting the angle corresponding to S/R with respect to the desired normal angleθ'.
