摘要

Apparatus for cleaving an optical fibre comprises two hand-operated pivotted jaws (11 and 12). The optical fibre (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 fibre. Closure of the jaws brings the blade against the fibre which it scores to a depth limited by the stop member (21) on the upper jaw (11) bearing against the upper surface of the fibre (15), and by yielding of the blade (18). The resilient mounting (20) of the blade (18) is such that the maximum force which cab 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 fibre to produce cleaving.
