Abstract

PURPOSE:To reduce the coupling loss of a single mode fiber by giving certain correlations between the direction of eccentricity of the optical fiber guide hole of an optical connector ferrule and the direction of coupling of an optical connector plug to an adapter to attach the optical connector ferrule to the optical connector plug. CONSTITUTION:An optical connector ferrule 1 consists of a collar part 11, a resin molded part 12, a coupling part 14 around which a metallic pipe 13 is formed into one body, and an internally provided optical fiber guide hole 15. An extent 16 and a direction 18 of eccentricity of the optical fiber guide hole to the ferrule are precisely measured, and a mark 17 or a ruggedness 19 indicating the direction of eccentricity is provided on outside peripheral surfaces of ferrule collar parts 11 and 11'. The mark 17 on the optical connector ferrule 1 where this mark 17 of the eccentricity direction 18 is provided on one side of the regularly polygonal collar part 11 of the ferrule and a projecting part 3 provided on the outside peripheral surface of an optical connector plug 2 are allowed to correspond to each other to attach the optical connector ferrule 1 to the optical connector plug 2, and the direction of eccentricity of the optical fiber guide hole 15 is limited to a certain angular range to perform coupling. Thus, coupling is performed with a very small loss relatively easily.
