  • Apparatus for tightly fixing an optical connector to an optical cable
    Patent number: 7215868
    Abstract: In a fixing apparatus for fixing an optical connector to an optical cable having an optical fiber and wire members arranged around the optical fiber, the fixing apparatus includes first, second, and third holding members. The first holding member is adapted to be inserted between the wire member and the optical fiber. The second holding member is adapted to be disposed outside the wire members, the second holding member cooperating with the first holding member to tightly hold the wire members therebetween. The third holding member surrounding the second holding member and having an axial end portion adapted to be engaged with the second holding member in a rotation direction with respect to the optical cable. In addition, the third holding member has another axial end portion adapted to be connected to the optical connector.
