The optical fiber 141 and the optical fiber 142 can be a plastic optical fiber or a glass optical fiber, and the two pairs are relatively self-contained, and the number of optical fibers can be increased or decreased according to the application requirements. Each set of optical fibers is respectively accommodated in each set of perforations of the base 11 () to transmit optical signals between the two optical fibers of each set. The stepping motor 120 drives the wheel 13 to rotate. Each rotation of a specific angle of 200817748 degrees, the filter on the wheel is placed between each group of fibers, because each group of choppers can be filtered, and the wavelength is different. Therefore, when the reel 130 continues to rotate, the calendering wavelength switching device 100 can simultaneously output light of different specific wavelengths, and can continue the switching operation. Referring to Figure 2, there is shown a side cross-sectional view of an optical wavelength switching device in accordance with a preferred embodiment of the present invention. The end of the figure is connected to the base, and the rotary pumping (2) is set to 2 P and placed in the shaft hole 111. Each of the optical fibers 141 and the optical fiber 142 includes an optical axis close to the end of the rotating wheel 13A. The focusing mirror 150 is used to ensure that the optical signal emitted by the optical fiber 141 can be accurately transmitted to a specific distance. The optical fiber 142 is or is collimated by the optical fiber 142 to the optical fiber 14 J. Referring to Fig. 3, there is shown a front view of a portion of a base and a wheel included in an optical wavelength switching device in accordance with a preferred embodiment of the present invention. The base includes a shaft hole ill, a plurality of positioning holes 112 and a plurality of perforations ιΐ3. The turret 130 includes a shaft hole 131, a plurality of locating holes 132 and a plurality of filters 13 3 . The shaft hole 111 and the shaft hole 131 are located on the same axis, and the shaft of the stepping motor is passed through the shaft hole 13 1 and accommodated in the shaft hole u丨. The arrangement of the plurality of positioning holes 112 is exactly the same as the arrangement of the plurality of positioning holes 132. Each of the positioning holes 112 can be coaxial with a positioning hole 132 for the positioner counter wheel disposed outside the base 110.丨3〇 to locate. The arrangement of the plurality of perforations 113 is exactly the same as that of the plurality of filters 133, and the perforations 113 are for the optical fibers to be inserted from the outside of the susceptor. A filter of 133 is included as a filter. Each of the filters 133 can have the same or different bandpass wavelengths, so each filter 133 can filter different specific optical wavelengths or specific optical bands, respectively. Among them, the filter can be processed by coating, or by the characteristics of the component material itself. / § When the reel 130 rotates, each of the filters 133 will be on the same axis as each of the perforations 113, and the optical signals emitted from the optical fibers received in the perforations 113 can be filtered out to certain wavelengths or light. Band. Referring to Figure 4A, a schematic diagram of a wheel comprising four different sets of filters in accordance with another preferred embodiment of the present invention is shown. The runner 13() contains 12 filters, and the 12 filters are divided into 4 groups, each having 4 filters of 4 different specific optical bands. One of the first filters 1331, the second filter 1332 and the third filter 1333 have the same filter, i.e., the same specific wavelength or band of light can be filtered. Referring again to Figures 4B, 4C and 4D, respectively, a schematic diagram of a clock comprising four sets of different filters rotating 90 degrees clockwise, 180 degrees and 270 degrees, in accordance with another preferred embodiment of the present invention. As can be seen from the figure 3, the rotating wheel 130 rotating in units of 9 degrees of angle can cause the first filter 1331, the second filter 1332 and the third filter 1333 to sequentially pass through the 12 undulators. position. This means that all of the fibers on either side of the reel 130 can be filtered by the set of fibers in the same specific wavelength or optical band. In addition to its three sets of fibers in 200817748, the wheel 130 can sequentially filter out four different specific optical wavelengths or optical bands. Referring to FIG. 5, a schematic diagram of sequentially switching different wavelengths of each group of channels according to another preferred embodiment of the present invention is shown. There are 12 channels composed of several fibers on both sides of the filter 16〇. With the 4A, 4B, and 4D diagrams, the 5th figure expands the (1) solid damper in the above four figures into 12 channels. Explain the actual operating conditions of optical wavelength switching. f) Divide the above 12 channels into four groups, each of which outputs the same wavelength of light at the same time. The four sets of light wavelengths are defined as; λ2, and again 4. The wavelengths of light outputted by a group of channels 1401, 1405 and 1409 are the same as λι, λ2, λ3 and ;14. The wavelengths of the light output by the second group of channels 1402, 1406 and 1410 are again 2, and the factory forks and the ^. In the second group, the wavelengths of the light output by the 1403, 1407, and 1411 are several, and are 1 and 2 in length. The order of the light wavelengths of the fourth group of channels 14〇4, 14〇8 and 1412 is; I 4, 3, 2 and 1; In this way, it is possible to achieve different wavelengths of specific light at the same time, and to switch and output different specific wavelengths in sequence. With the above structural composition and embodiment, the present invention has the following advantages compared with the conventional ones: 1. Since the base and the rotating wheel of the light wavelength switching device have positioning holes, the positioning device disposed on the outer side can be positioned, so The incidence of alignment errors (aHgnnlelu error) can be minimized. 2. By providing a focusing mirror at both ends of the optical fiber opposite to the input end, the signal loss attenuation which is inevitable when transmitting the optical signal can also be changed. 200817748 3. The number of optical fibers at the output end and the input end is equal, and The wheel has a plurality of coating filters, so the optical wavelength switching device can simultaneously output different specific wavelengths of light, and can sequentially switch the specific wavelength of light outputted by each output terminal. The present invention has been disclosed in a preferred embodiment as described above, and is not intended to limit the invention to those skilled in the art, and without departing from the spirit and scope of the invention, The scope of the invention is defined by the scope of the appended claims.
