Optical fiber end preparation: a new method for producing perpendicular fractures in glass fibers, coated-glass fibers, and plastic-clad fibers
G.D. Khoe, Gerard Kuyt, J. Luijendijk · Applied Optics · 1981
A new method for cutting optical fibers is presented. A smooth scratch, without any visible cracks and chipping, is circumferentially made around the complete periphery before the fiber is fractured by simple axial tension. Break angles of 0.5 degrees are easily obtained. Coated-glass fibers and plastic-clad fibers are cut properly for the first time owing to the novel scratching procedure. A compact tool is used to perform the required sequence of operations automatically.
