    摘要： An optical fiber connector assembly has a holding member and a housing having a cavity for receiving the holding member. The holding member has a first surface, a second surface, grooves formed in the first surface for holding respective ferrules each supporting an optical fiber element, and through-holes for respectively receiving therethrough the optical fiber elements and for communicating the grooves with the second surface. The housing has a base surface, through-holes extending through the base surface, and side surfaces defining with the base surface a cavity for receiving the holding member so that the through-holes of the holding member are communicated with the through-holes of the housing for receiving therethrough the optical fiber elements.

    摘要： A ferrule for use in an optical connector enabling effective suppression of the increase in the insertion loss resulting from repeated attachments/detachments of the optical connector. In the ferrule for use in the optical connector, a plurality of grooves 17 are formed in a fitting surface 16A of a ferrule main body 11 located between the ferrule main body 11 and a connection sleeve SL. And, a ferrule 2 for use in an optical connector, a plurality of concentric annular grooves 27 are formed in a connection end surface 24 of the ferrule main body 21 having a connection end 22A of the optical fiber 22 exposed thereon.

    摘要： A ferrule for optical connectors which is of funnel type comprising a ferrule body, containing a small-diameter hole and a large-diameter hole having a larger diameter than the small-diameter hole, the small-diameter hole and the large-diameter hole being formed so as to allow an optical fiber to pass therethrough and communicate with each other, the ferrule further comprising a buffering hole having a diameter which is larger than that of the small-diameter hole but smaller than that of the large-diameter hole, the buffering hole being formed between the small-diameter hole and the large-diameter hole and containing groove of concave and convex pattern on the internal surface of the buffering hole. The ferrule body further contains three lines of protrusions extending along the axial thereof, which are formed on the internal surface of the large-diameter hole.

    摘要： Universal optical fiber connectors and their basic plugs, wherein the optical fiber connectors have some common elements for their connector-functions to permit an installation of optical fiber into one of the different type connectors for establishing their connection more easily and to facilitate a tuning operation with positioning key maintaining the same direction between eccentricity of the fiber core and the key. The basic plug has a ferrule, a spring element, and a cylindrical tube. The spring element is positioned between a ferrule and a cylindrical tube, so that it exerts forces toward them in an axial direction. The ferrule has a common dimensional structure for securing an optical fiber and has a shape enabling the connection to any one of various kinds of housing members. Thus, the basic plug connects separate optical fibers together through the housing member.
