[0003] In the research and development and production of CPON products, two laser display screens are usually installed on the base plate. The two laser display screens are symmetrically arranged on both sides of the base plate, and the BASE is arranged on one side of the laser beam generator switch. After the laser beam generator emits laser, it is refracted through the filter in the BASE on the laser display screens on both sides, and a red dot appears on the laser display screens on both sides. If the red dot is within the circle on the laser display screen, the optical path is qualified, otherwise the optical path is unqualified.
[0004] In the prior art, BASE is composed of multiple filters. Since each filter is mounted separately, the position and angle errors of each filter accumulate to a large extent, resulting in that some filters cannot converge light to the center of the light hole as required after mounting, causing subsequent emission coupling or reception coupling to produce light polarization, resulting in coupling failure, greatly increasing manufacturing costs and affecting the yield rate. Therefore, it is necessary to correct the light polarization of BASE in a timely manner after it occurs. Utility Model Content
