Abstract
A ferrule and method are presented that fuses optical fibers, capillaries and the like to ferrules while reducing deformation of the fused component and the ferrule and minimizing stresses within the assembly. Reduced deformation and stress is accomplished by providing high contact angles in a symmetrical, short section of fusion in fusing the component carried by the ferrule to the ferrule. It is particularly applicable to hermetic terminations of polymer clad fiber optics where irregular glass fusion joints cause irregular light leakage at the fiber launch but benefits are significant when used for other fiber and capillary architectures as well.
