Abstract
A tool for actuating an optical fiber splice having an actuation element which moves longitudinally within the splice. The tool includes a base having a recess for receiving the splice, and two channels parallel to and aligned with the recess. A pair of fiber holders are used to manipulate the fibers, the holders being placed in the channels. The channels have ramped surfaces inclined toward the recess to facilitate proper insertion of the fibers into the splice, and the ramped surfaces have slots therein allowing passage of push rods which bias the holders toward the splice, providing positive abutment of the fiber end faces within the splice. Backstops are formed at the outside ends of the channels, and sidewalls are formed adjacent the backstops. A lever is pivotally attached to the underside of the base, and has an actuation stud which passes through an opening in the base and contacts the actuation element of the splice. When the lever is moved from an unactuated position to an actuated position, the stud forces the actuation element of the splice to clamp the inserted fibers. Means may be provided to retract the push rods, and a magnifying glass is provided to facilitate visual inspection of the inserted fibers.
