、実装時に光ファイバの折損防止が図られる。As described above, according to the present invention, there is provided a splitter including a plurality of dichroic mirrors that are parallel to each other and inclined at 45 degrees with respect to the direction of incidence of an optical signal, and a parallel optical signal is input to the splitter. a mixer comprising a collimating lens for demultiplexing, a plurality of other dichroic mirrors tilted at 90 degrees with respect to each dichroic mirror of the splitter and parallel to each other; and a mixer for focusing the parallel optical signals from the mixer. A shirt filter that has a condensing lens for emitting light, and a plurality of light transmission holes that are movably interposed between the demultiplexer and the mixer and allow selective transmission of optical signals from the demultiplexer to the mixer. Since the plate is disposed inside the casing, the optical axis precision is improved and the optical path can be shortened, and as a result, it is possible to construct a small original switch device with less optical attenuation. Further, since a pair of optical fibers corresponding to the collimating lens and the condensing lens are connected to the coupler that is detachably attached to the casing, the optical fibers are not directly extended from the casing, and the optical fibers are not directly extended from the casing. This improves mounting workability and prevents optical fiber breakage during mounting.
