<p>An improved tool for cutting optical fibers by the scribe-and-break technique is disclosed. The tool has a scribing edge (18) transversely directed with respect to, and normally spaced from, an arcuate convex fiber supporting surface (22). When moved normally with respect to the fiber supporting surface (22), the scribing edge defines a scribing plane. Spring members (14), located on opposite sides of the scribing plane, are compressed between the fiber supporting surface (22) and a bearing surface (16), causing the optical fiber (60) to be clamped between the spring members (14, 30) and the fiber supporting surface (22). This compression also forces the spring members (14) to slide longitudinally along the fiber supporting surface (22) away from the scribing plane, imparting an axial tensile stress to the optical fiber (60). The optical fiber (60) is finally scribed by the scribing edge (18) resulting in propagation of a fracture over the cross section.</p> |
