Abstract: In a connector, an optical fibre cable is passed through a sub-assembly comprising a crimp body and collet. Then a sub-assembly comprising a threaded shell and ferrule is screwed onto the collet so that its tines are compressed in the ferrule onto the buffer coating of the cable at a location behind an end portion from which the buffer coating has been removed. Thus, the optical fibre passes through a precision hole for its projecting end to be removed by a cleaving blade passed across a slot. Two connectors are fixed to opposite ends of a rigid coupler by coupling nuts to bring opposed fibres into register.

Abstract: An optical fiber has an insulative coating portion stripped leaving an extent of bare fiber. A fiber contact housing has an opening within which the fiber is located in the interstice of three cylindrical pins arranged parallel and contacting each other. The inner end portions of the pins are ridged to clamp onto the insulative material covering the fiber adjacent the bare fiber. A shield is placed around the inner ends of the pins and crimped about the pins and fibers. By use of a fixture the faced-off end of the fiber is located just inwardly of the outer ends of the pins, this assembly constituting a "contact" and a second fiber is assembled into a second "contact". An alignment sleeve has a leaf spring wall to resiliently retain and align the two fiber contacts received within the sleeve ends in proper fiber end spacing relation.
