Claims

[Claims for Utility Model Registration] (1) A cylindrical core portion with a large diameter, and a refractive index smaller than the refractive index of the core portion formed in contact with a side surface of the core portion and surrounding the core portion. an optical coupling portion having a cladding portion having a radial angle, and a disk-shaped semi-transparent portion formed perpendicularly to the axial center of the core portion and covering at least all of the core portion; A plurality of optical fibers are fixed in contact with each of both end faces of the optical coupling part so as to enable bidirectional transmission of optical signals, and the optical fiber is connected to the optical fiber from any one of the optical fibers. The optical splitter branches the optical signal emitted toward the coupling portion and inputs the optical signal into all the optical fibers, and the semi-transparent portion partially transmits the optical signal incident on the semi-transparent portion. An optical branching device that reflects the remaining optical signal. (2) Utility Model Registration In the optical splitter according to claim 1, the semi-transparent part provided in the optical coupling part has a part that transmits the optical signal and a part that reflects the optical signal on one plane. A light branching device characterized by being a light reflector arranged.
