TH22830EX - Optical fiber cutting methods and tools - Google Patents

Abstract

The whip cutting tool consisting of fiber clamping units (2 and 4), each containing A rigid block (6 or 6) that is cut with a flexible sheet (8 or 8 ''), for example. Block synthetic felt (6 or 6 '') can be moved relative to the open position for optical fibers (OF), between the elastic pads (8 and 8 '') and the closed position to clamp the fibers (OF). Between the sheets (8 and 8 '') fibers (9) are held to distribute tensile forces (P1) to the fibers (OF), causing them to slide between the elastic sheets (8 and 8 '') in the closed position of the block. (6 and 6 ''). Before the two fibers are placed between the sheets (8 and 8 ''), the fibers are formed with a N V-shaped incision, where the fibers are torn apart from the sheet (8 and 8 '') has been shaped in such a way that the fiber (OF) slides between the sheets (8 and 8 ''), initially curved. At approximately the notch (N) after the direction of curving, the fibers (OF) are curled back. Thus, the fibers (OF) are torn apart at the incision (N) under the tension (P1) applied to the fiber (OF) by the fiber carrier (9). One end of the fiber (OF) is then pulled away from the sheet (8 and 8 '') by the fiber holder 9.

Claims (1)

1. Method of cutting optical fibers (OF) that have created a notch. (N) up within it The method consists of The process of clamping the fibers (OF) between the faces against each other. (11,11,32,42) of the first and second parts (8,8) with a notch (N) between it and where the compression is applied to the fiber (OF) method. It has characteristics in such a way that During this compressive application, the fiber (OF) bends approximately the indent (N) in the first direction, usually to close the notch (N) and to apply the tension to the fiber (OF).
