- 19 - Abstract of the Disclosure An optical power distributor comprises first and second sections each of which consists of at least two optical fibers thermally fused at one end portion, which end portion consists of a united cladding having at least two cores packed in the cladding, the end faces of the end portions being butted on each other and spliced by means of thermal fusing in such a manner that at least one core of the first section overlaps at least two cores of the second section at a splice plane, whereby optical power is distributed through the splice plane. A method for manufacturing an optical power distributor comprises the steps of arranging a number of optical fibers; heating them and pulling them at both ends to form a biconical taper waist; cleaving them at the waist into two sections; rotating one of the sections by 90°; and butting the ends of the sections and thermally fusing them so that, at the thinnest portion of the waist, one of the cores of one section overlaps both cores of the other section.
