Problems solved by technology

However, the screening efficiency and accuracy of this manual screening method cannot meet the requirements of mass production; moreover, in the channel switching of the MEMS OSW optical switch, it is completed from the Hitless point to each channel in an approximately straight-line path. Point switching, if there are other channel points on the straight path from the Hitless point to a certain channel point, optical signal interference will occur during the switching process, reducing the screening yield of the optical switch module
