In addition, on one hand, the light guide column penetrates out of the optical module, the integrity of a structural member of the optical module is not damaged, and therefore the optical module has good EMI performance; on the other hand, through the switching action of the indicating lamp circuit board assembly, compared with the traditional mode that the indicating lamp circuit board assembly is placed on a photoelectric conversion circuit board assembly with a tense size, the indicating lamp circuit board assembly is placed to increase the packaging size of the indicating lamp, so that the alignment of the light guide column and the indicating lamp is facilitated, and the tolerance in the assembling process is improved.

It should be noted that: it should be noted that: "first," "second," and the like are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

In addition, the technical solutions described in the embodiments of the present invention can be combined arbitrarily without conflict.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
