Based on this, the wavelength division multiplexing optical device 2 may have two insertion holes (not shown in the drawing) spaced from each other, and the two insertion holes may be respectively mated with the two plugging portions.
For this embodiment, when the optical processing devices 4 and the wdm optical devices 2 need to be optically coupled, two positioning portions 52 in the positioning member 5 may first pass through the circuit board 1, and then two plugging portions in the positioning member 5 may be plugged into two jacks in the wdm optical devices 2.
In the above two embodiments, in order to improve the connection stability between the positioning member 5 and the wavelength division multiplexing optical device 2; the aperture of the insertion hole 521 in the positioning member 5 may be tapered in the insertion direction of the insertion portion 211 in the wdm optical device 2; based on this, the plug portion 211 in the wavelength division multiplexing optical device 2 may be an elastic plug portion, that is, the plug portion 211 in the wavelength division multiplexing optical device 2 may be made of an elastic material, such as silica gel, plastic, or the like. Correspondingly, the aperture of the jack in the wavelength division multiplexing optical device 2 can also be in a shrinking trend along the plugging direction of the plugging part in the positioning piece 5; based on this, the plug-in part in the positioning element 5 can also be an elastic plug-in part, i.e. the plug-in part in the positioning element 5 can also be made of an elastic material, such as silicone, plastic or the like.
It should be understood that the foregoing embodiment is merely a preferred implementation of the embodiment of the present invention, and is not the only limitation of the technical features related to the positioning portion 52 and the wavelength division multiplexing optical device 2 by the embodiment of the present invention; in this regard, those skilled in the art may flexibly set according to the actual application scenario on the basis of the embodiment of the present invention.
