  • Patent number: 6081642
    Abstract: An optical connector secures an optical cable having a fiber optic core and a coating. The optical connector includes the front side of which is provided with ferrules and the rear side of which is provided with openings for inserting optical cables. Cable guides support the cables. A cover of the housing includes pairs of guide plates which flank the cables when the cover is attached to the housing. Each guide plate includes an elongated stopper on the face where the cable is flanked. The stopper has a rectangular cross-section and a sharp edge at its open end. When the cover is placed on the housing, the sharp edge cuts through part of the coating and immobilizes the cable against axial movement.
