Abstract

PURPOSE:To decrease the quantity of reflection light on the connecting end of optical fibers whose core diameter is different, by deflecting in parallel the center axes of the connecting end of the optical fibers. CONSTITUTION:In case when a fiber 1 having a core 2 of small diameter, surrounded by a clad 3 is connected with a core 6 of large diameter, surrounded by a clad 7, when the axes of both the cores are deflected and connected in parallel as shown in the figure, decrease of the quantity of light which is transmitted from the core to the core 6 is a little comparatively, and the quantity of light which is transmitted from the core 6 to the core 2 decreases more than its area ratio. Accordingly, reflected rays at the side of a fiber 5 in the connecting end decrease remarkably, and quality of an optical signal which is transmitted from the optical fiber 1 to 5 is elevated.
