ABSTRACT:
A method and a device for cutting or breaking a plurality of light waveguides which are contained in a cable characterized by clamping each of the light waveguides at spaced points to hold a portion of the waveguides between said points parallel to each other, positioning the light waveguides extending between the points over an anvil with each of the light waveguides being parallel to one another, applying a common tension force to each of the waveguides at the other side of the anvil, applying a vertical force to each of the waveguides at a point on one side of the anvil to apply an axial prestress to each of the waveguides extending across the anvil, and notching each of the prestressed light waveguides at a point in contact with the anvil to cause separation of each of the waveguides at its notch.
