Optical fibers used in a star-type optical coupler each have a light signal input terminal and a light signal output terminal. A light signal passes through the optical fibers in a linear displacement. According to the present invention, linear displacement of the light is transformed into a generally circular movement through a coupling ring, such that the input terminals of the optical fibers need not be grouped on the same side of the optical fibers, and likewise for the output terminals of the optical fibers. Thus, the input terminal of a first optical fiber and the output terminal of a second optical fiber can be arranged adjacent to each other, so as to form a pair. When the input terminal is thus paired with the output terminal, the star-type optical coupler can be connected to peripheral optical communications apparatuses more easily.
