  • Adaptable connector for a fiber optic testing device
    Patent number: 4413880
    Abstract: A connector is provided for connecting unterminated optical fiber cables to test sets or the like. The connector has a cable adapter section and an optical fiber adapter section. The cable adapter section is partly slotted and has a cylindrical bore for receiving the cable. The outer dimensions of the cable adapter section cooperate with a sliding ring to form a clamp for holding the cable securely. The optical fiber adapter section has a cylindrical bore coaxially aligned with the bore of the cable adapter section and receives the unsheathed optical fiber and maintains it in precise optical alignment within the test set. Disposed between the cable adapter section and the fiber adapter section is a conical chamber for guiding the optical fiber to the bore of the fiber adapter section.
