通りである。The present invention aims to provide an optical communication element that has a small difference in the amount of distributed light, has a simple structure, and is easy to manufacture and can be used as a distributor or combiner. An appropriate number of input optical fibers and an appropriate number of output optical fibers are inserted into a fully woven container for scattering, and if necessary, a reflector plate is provided in the container to reverse the phase light of the input optical fibers. If you explain the implementation example, it is as expected.

径が２〜３ｃｒｎの容器である。FIG. 1 is a cross-sectional view of one embodiment of the present invention, where 1 is an inner surface of a sphere i*+, and the surface is made of MgOa with a high degree of pure change.
This container has a spherical surface having a diameter of 2 to 3 crn and is coated with a scattering coating 2 made of sprayed wood.

射板５がヌテム６で支持されて設けられている。One input optical fiber 3 is inserted into one side of the container 1, and all n output optical fibers 4 are inserted into the opposite part, and a reflector 5 is placed inside the container 1 facing the input optical fiber 3. supported and provided.

配置され、しかも表面ケＭｇＯで被覆７しである。Against! 1-14 and 5, the direct light from the input optical fiber 3 directly enters the output fiber 4, and each output fiber is injected directly into the output fiber 4.
It is arranged to disperse well to prevent VC stoppage, and the surface is coated with MgO.

ー４に夫々殆んど等しい光量の光が分配さＪ’Ｌる。Since the VC is configured as described above, when an optical signal is given to the input optical filter 3, the incident light is Iyl·141y, 5
The light is reflected from the VC and is scattered by the spherical surface 1a1 to the output optical fibers 4 of the output optical fibers 11 with almost the same amount of light.

い。In this case, the case where there is one Ipar 3 (input optical fiber) is shown as an example, but it is also possible to use several fiber optics.In that case, a part of the output optical fiber can be connected with a human-powered 9-Iber VC connector to make the optical fiber far away. It is possible to use the optical fiber in a similar manner, or to give a common input optical fiber a fiber optic fiber with different wavelengths, and distribute the combined light equally to the output optical fiber. It is easy to use and its application value is extremely high.
