Abstract
Apparatus for cleaving an optical fiber comprises two hand-operated pivoted jaws (11 and 12). The optical fiber (15) is supported along the lower jaw (12) and held by resilient clamps (24 and 27) on the upper jaw (11) when the jaws are closed. A blade (18) is resiliently coupled to the upper jaw on a parallelogram linkage (20) and protrudes beyond a stop member (21) by an amount substantially equal to the intended depth of intrusion of the blade into the fiber. Closure of the jaws brings the blade against the fiber which it scores to a depth limited by the stop member (21) on the upper jaw (11) bearing against the upper surface of the fiber (15), and by yielding of the blade (18). The resilient mounting (20) of the blade (18) is such that the maximum force which can be applied to the blade is the amount required to produce a score of the desired depth. Further closure of the jaws then applies a longitudinal tension to the fiber to produce cleaving.
