A plurality of optical fibers 2.3.4 are installed, one of which is the fiber for the optical signal source, and the other two optical fibers 3.4 are for optical distribution. Although only three optical fibers are shown in the illustrated embodiment, it is also possible to provide a plurality of holes 5, 6 etc. in the main body 1 and connect other optical fibers to these for distribution. good. When there is no need for distribution of these holes, the light refraction of the main body 1, the refraction 1. ．． Insert a dummy 7 etc. made of the same material as the hole to cover the hole.

There are multiple optical fibers attached to this main body, and in the figure, four optical fibers 12, 13, 14, and 15 are attached, and one or two of these are the fibers that are the source of the optical signal. and the others are distribution fibers. In addition, in addition to these fibers, it is necessary to make appropriate mounting holes so that a large number of fibers can be attached, and a material with a low refractive index or a reflective film 18 is used on the outer peripheral surface of the main body. It is also the same as in the above embodiment that is coated. In this embodiment, the attached fibers are located radially on the same outer surface to provide good light distribution.
1 1. Furthermore, in the first and second embodiments, by evenly mixing the light dispersing material in the glass or shirasanak constituting the main body, Together with the coating material on the peripheral surface, the dispersion and diffusion of light inside the fiber becomes uniform, and uniform optical signals are input to the distribution fiber.

。As explained above, the optical distributor of the present invention has a main body made of transparent glass material, a plurality of optical fibers are connected to the main body, or a plurality of connection holes are provided in the main body. Since the outer peripheral surface is covered with a low refractive index material or a reflective film, the light input as an optical signal from one optical fiber is evenly dispersed inside the main body, and the light is distributed evenly to the required number of fibers. It has an excellent effect of accurately distributing the light and transmitting it simultaneously.The main body has multiple connection holes, so multiple arbitrary optical fibers can be connected, and multiple optical fibers can be connected. It can collect signals and distribute them to multiple sources at the same time. In other words, by distributing a single light (C3) into multiple,
It is also extremely easy to distribute multiple optical signals to multiple units or to aggregate multiple signals into a single signal.
