Abstract
A method of manufacturing a fiber-optical coupling element by fusion of two monomode fibers. The fiber cores are made of a core glass, the American softening temperature of which is at least 80.degree. C. higher than that of the cladding glass. The fibers are heated to a temperature between 520.degree. and 560.degree. C. By the method, fibers can be fused to form a coupling element without undesirable deformation of the fiber cores.
