Problems solved by technology

The horizontal beam will be refracted when passing through the inclined draft slope 121, causing the optical axis of the beam to shift downward (that is, rotate clockwise), which will also cause the beam to deviate when it is focused into the optical fiber, that is, after focusing The light cannot be coupled into the fiber from the center of the fiber, which will greatly reduce the coupling efficiency of the optical module
