Abstract
There are disclosed an optical fiber junction device and a method of making the same. The method comprises the steps of providing a central inner pipe or rod of glass, arranging a plurality of optical fibers around the inner pipe or rod, and externally heating the optical fibers and the central inner pipe to form a thermally fused assembly having cores of a sectorial cross section. The inner pipe may include a tapered portion having a reduced diameter. The optical fibers may comprise optical fiber junction units each composed of a plurality of optical fibers.
