摘要： A universal optical connector adapter that can be used to connect optical connector plugs of the same or different types having ferrules fixed at ends of optical fibers. The universal adapter has first and second housings each having at one end a coupling portion for detachably coupling with an optical connector plug of a given type and on an opposite end a base plate having a reference plane. A cylindrical coupling member is rotatably held inward of the coupling portion of the first housing and incorporates a sleeve for fitting ferrules into opposite sides thereof. A male thread is provided on an outer periphery of the coupling cylindrical member and a female thread is provided in the coupling portion of the second housing on a side opposite to that in which an optical connector plug is coupled. The female thread is removably couplable with the male thread. The first and second housings can be coupled together so that the reference planes are closely contacted and the male thread and female thread are removable.

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.
