Definitions
- the present invention relates to a device for cutting polymer optical fiber optical waveguides (POF-LWL) with a lower jaw, an upper jaw and a blade.
- PPF-LWL polymer optical fiber optical waveguides
- Polymer optical fibers are optical fibers that are increasingly used, among other things, for the transmission of data. They are made of transparent plastic, e.g. made of high-purity PMMA (plexiglass), and have a typical diameter of 1 mm. They are protected by a jacket extruded thereon so that a typical optical fiber cable with a jacket has a diameter of approximately 2.3 mm. For low-loss coupling and decoupling of light, e.g. for plug connections, the optical quality of the end surface is of crucial importance.
- the end surface of a POF fiber-optic cable should be reflectively smooth and flat, perpendicular to the fiber axis, show no breakouts, generate as little scattered light as possible and no additional changes in refractive index, e.g. due to inclusions in the area below the end face. Furthermore, such an end surface should be simple, i.e. quickly reproducible and inexpensive to manufacture.
- the present invention has for its object to improve a device of the type described in such a way that end surfaces of POF fiber with high quality, i.e. the lowest possible damping can be produced in a single operation.
- the present invention is based on the idea of creating the same conditions on both sides of the cut surface to be applied, by applying radial pressure to both sides. This prevents, among other things, that the end face makes an angle with respect to the POF axis of approximately 80 °, which is the case with devices in which the optical waveguide is only clamped on one side. In the latter case, the cutting blade dodges to the side with the lower compressive stresses and therefore less strength and thus creates an oblique cutting surface.
- the figure shows the device according to the invention for cutting the POF fiber optic cable in longitudinal section.
- the device 1 essentially has a lower jaw 2 and an upper jaw 3 and a blade 4.
- the optical waveguide 5, which is surrounded by an extruded jacket, is inserted into a groove with a semicircular cross section in the lower jaw.
- the diameter of the groove is slightly undersized compared to the diameter of the optical fiber cable, i.e. with a cable diameter of 2.3 mm, the diameter of the groove is of the order of 2.2 mm.
- a corresponding groove is incorporated in the upper jaw 3, which locks the optical fiber cable 5 from above.
- the two clamping jaws are pressed towards one another in order to exert a defined radial pressure on the optical fiber cable 5.
- the edges of the grooves in the lower and the upper jaw 2, 3 are slightly chamfered or rounded in order to form a bulge of sheathing material of the optical waveguide cable in the area of the contact surface of the lower and to prevent upper jaws.
- the blade 4 is guided in a slot 6 which passes completely through the upper jaw in the cutting area and partially through the lower jaw.
- the slot 6 guides the blade 4 with the least possible play in order to prevent the cutting surface from deflecting in the axial direction.
- the cutting edge 7 of the blade 4 is ground symmetrically and has the smallest possible wedge angle, which, depending on the blade material, enables the optical fibers to be cut without destroying the blade.
- the symmetrical cut of the cutting edge means that both cut surfaces of the cut optical fiber are flawless.
- the cut made by the blade can be made along an axis that goes through the optical fiber and the movement can be rectilinear, but it is also possible to make a pulling cut, that is to say during the cutting of the optical fiber the blade becomes obliquely forward or backward moved in the gap 6.
- the optical waveguide is subjected to radial pressure on both sides of the slot 6 and that the same conditions prevail on both sides of the blade. Furthermore, it must be prevented that the critical breaking speed of the fiber material is not exceeded during the cut, as a result of which breaks could propagate into the interior of the fiber. With PMMA this is 340 m / s.
- the wedge angle of the cutting edge of the blade is also important, which should be as small as possible in order to also keep the axial pressure load on the cutting surface to a minimum. A compromise must be made between the hardness of the blade material and possible blade grinding. It has been shown that the surface quality of the cut surface is even better when using a diamond saw than in the case of processes in which the cut surface is reworked by hot-plate processes or polishing.
- the device shown would have to be modified to the extent that an axial application of pressure is made possible. This can be done, for example, by a spindle mechanism or the like.
