Abstract
The invention is an apparatus and method for cutting optical fibers including a pair of slip-grasping clamps arranged to grasp an exposed optical fiber between them such that a slip-grasping force on the optical fiber is maintained constant. An injuring edge is urged against the optical fiber at a point between the two clamps to initially injure the optical fiber. A pressing block is then urged against the optical fiber from a side opposite the initial injury so that tension is exerted on the optical fiber by the slip-grasping force of the clamps, thereby cutting the fiber.
