Embodiment Construction
[0011] Below in conjunction with accompanying drawing, the present invention is described in detail, as figure 1 It is a schematic diagram of the optical switch structure of the present invention. As shown in the figure, the structure of the present invention includes three self-focusing lenses 1 connected with optical fibers. These three self-focusing lenses are respectively located in the light incident direction, reflection direction and transmission direction, and the incident The light will be reflected or transmitted on the optical filter inlaid on the turntable, and the A-type filter 2-A, B-type filter 2-B and light-absorbing filter 2-C are alternately inlaid on the turntable, as a specific wavelength Selective filter, A-type filter only transmits light with a wavelength of 1550nm, and B-type filter only transmits light with a wavelength of 1310nm. When the switch is working, the turntable rotates, and the light from the incident light self-focusing lens contains two wa...
