Abstract: Test apparatus for evaluation of multiconductor cable assemblies inlcude plural diverse indicators for each dedicated conductor pair and is responsive to single operator input to selectively drive the indicators for indication of proper cable assembly condition, conductor shorts, open assembly condition, and connection polarity reversal per assembly pair.

Abstract: An optical fiber cleaving device having a movable scoring element mounted between a movable arm and a fiber support member. The scoring element is responsive to the movement of the movable arm to move relative to both the movable arm and the fiber support member. This relative movement permits regulation of the force at which the scoring element scores the fiber supported on the support member. Such regulation provides for a more precise depth of score reducing adverse effects thereof.

Abstract: In terminating an optical element, such as an optical fiber, a housing includes an entry aperture for the fiber and terminating apparatus defining mutually discontinuous surfaces in abutting relation to the fiber end face, the surfaces being spaced from one another in a circular locus having a diameter not greater than the diameter of the fiber.

Abstract: A method and tool are disclosed for use in cleaving fiber optic elements preparatory to a splice for joining of two such fiber optic elements. The method comprises the steps of first moving a grooving tool about the entire circumference of a fiber optic element to form a circumferential groove therein, and then stressing the fiber optic element in the vicinity of the groove to provide a clean, mirror type end surface of the element which is suitable for subsequent splicing thereof with another suitably prepared element. The tool which is useful in cleaving a fiber optic element comprises support means having a longitudinal axis for supporting the fiber optic element therealong, grooving means for forming a groove in the surface of the fiber optic element, and mounting means for mounting the grooving means to revolve about the longitudinal axis of the support means to circumferentially groove a fiber optic element about its entire circumference.
