ABSTRACT:
An optical fiber prooftester for exerting a controlled tensile force on spliced optical fibers includes a base member, a first optical fiber clamp in the form of a coil spring attached to the base and a sliding member mounted for movement on the base member. A second optical fiber clamp also in the form of a coil spring is fixed to the sliding member. A spliced optical fiber is mounted in the first and second clamps with the splice located between the clamps. A constant force wound spring acting between the base member and the movable member urges the movable member away from the first optical fiber clamp thereby applying a predetermined tensile force upon the splice.
