Abstract
A light input/output terminal modulecomprises a jacket tubeand a flange. A glass portionof the optical fiber is inserted in the center portion thereof. To efficiently remove the leaked light in a claddingto the jacket tube, the jacket tubeis made of silica glass or the same material as that of the cladding. The jacket tubeis fixed by fusion splicing or adhesion to the cladding so as to integrally unify the jacket tubeand the cladding. The beam diameter at the fiber end portion is enlarged by an optical component which fusion bonds the tip end of the optical fiber to the coreless fiber so that the optical power density at the light input/output terminal module is reduced.
