Working principle: in practical application, light enters a converging lens after passing through an optical element Z-block II, then enters an FA II or a capillary II at a transmitting end, and external light enters a turning prism I through an FA I or a capillary I with a collimating lens, and then enters the Z-block I for transmission; in the scheme, because a certain distance is reserved between the FA II or the capillary II and the FA I or the capillary I, the distance is 1-6mm according to the actual application requirement, at least one of the FA II or the capillary II, the FA I or the capillary I needs to be spatially aligned with the Z-block I or the Z-block II when in use, so that light between one group can be directly transmitted when being sent or received, and the other group is miniaturized by an integrated part, and deflection adjustment of the light direction is carried out through a turning prism I if deviation of alignment occurs in space;

in practical application, the Z-block I and the Z-block II can be used as transmitting ends or receiving ends according to the use requirement, and can be used for transmitting and receiving one by one, the number of channels is not limited to four channels, and devices matched with the Z-block I and the Z-block II are not limited to FAs or capillaries, and can be other components with the same function.

Example 2

Embodiment 2 is shown in fig. 2 as a preferred example of the present utility model, and the following modifications are disclosed on the basis of embodiment 1:

Working principle: in the scheme, the distance between the FA II or the capillary II and the FA I or the capillary I is reduced relative to the embodiment 1 (namely, the two are closer to each other), and the volume of the integrated part is further controlled, but in the case, because the distance is reduced and the volume is reduced, no method is available for ensuring the alignment of light transmission in space between the FA II or the capillary II, the FA I or the capillary I and the Z-block II and the Z-block I, so that the light transmission in space is not influenced after the volume is reduced, and a turning prism II is needed to be added between the Z-block II, the Z-block I and the FA II or the capillary II, the FA I or the capillary I, so that the output and input angles of each light to the light are adjusted through the turning prism II.
