Optical fibers typically comprise a protective polymer coating, frequently a dual coating. For splicing of fibers, as well as for many other reasons, it is necessary to remove the coating from a length of fiber. This can inter alia be accomplished by mechanical means, and stripping tools are known. Such stripping tools typically comprise a blade, or a pair of opposed blades, that cut into the fiber coating and are used to apply an axial (shear) force to the coating. Although prior art stripping tools work adequately in many circumstances, it is frequently difficult to cleanly remove relatively long lengths L of dual polymer coating from optical fiber. We have now discovered that removal of the coating from a length L of fiber is facilitated if the tool comprises a multiplicity of blades arranged such that the coating is cut not only at a point a distance L from the fiber end but also at a point L' from the fiber end, where L' < L. |
