  • Patent number: 4398793
    Abstract: An optical fiber connector including an insertion member having first and second annular portions, the first portion having a larger outside dimension than the second portion. When the connector is inserted on the fiber optic cable, the first portion of the insertion member underlies the insulation and fiber sleeves of the cable whereas the second portion of the insertion member underlies not only the insulation and fiber sleeves but also the outer shell of the cable. A ferrule is employed to mechanically stabilize the cable about the first and second portions of the insertion member of the connector. The cable, including its outer shell, is firmly held in position. Preferably, the ferrule includes one or more openings therein to even more firmly hold the outer shell in position.
