Referring to fig. 4, fig. 5 and fig. 6, fig. 4 is a schematic structural diagram of a second wavelength division multiplexing optical communication device according to an embodiment of the present invention, fig. 5 is a schematic first decomposition diagram of the second wavelength division multiplexing optical communication device according to the embodiment of the present invention, and fig. 6 is a schematic second decomposition diagram of the second wavelength division multiplexing optical communication device according to the embodiment of the present invention.
In some embodiments, the wavelength division multiplexing optical communication apparatus provided in the embodiments of the present invention may further include a positioning element 5; the positioning member 5 may be disposed on a side of the circuit board 1 opposite to the wavelength division multiplexing optical device 2, and the positioning member 5 may penetrate the circuit board 1 to be connected to the wavelength division multiplexing optical device 2. Specifically, the positioning member 5 may include: a main body 51 and two positioning portions 52 extending from the main body 51 in the direction of the wavelength division multiplexing optical device 2 and spaced from each other; wherein, the two positioning portions 52 may be connected to the wavelength division multiplexing optical device 2 through the circuit board 1. On this basis, each optical processor 4 may be attached to the circuit board 1 at an interval with the two positioning portions 52 as reference points, and may be located between the two positioning portions 52. Here, it is necessary to explain that the reference points of the two positioning portions 52 are actually position recognition points when the circuit board 1 is applied to an automatic mounter.
For this embodiment, when it is necessary to optically couple each optical processing device 4 and the wavelength division multiplexing optical device 2, the two positioning portions 52 may penetrate the circuit board 1 and be connected to the wavelength division multiplexing optical device 2; at this time, the wavelength division multiplexing optical device 2 inevitably forms a relative positional relationship with each optical processing device 4, and therefore, as long as the optical path coupling between each optical processing device 4 and the wavelength division multiplexing optical device 2 is optimal in the preset relative positional relationship, it is no longer necessary to adjust the relative position between each optical processing device 4 and the wavelength division multiplexing optical device 2.
Therefore, the embodiment of the invention does not need to repeatedly adjust the relative positions of the optical processing devices 4 and the wavelength division multiplexing optical devices 2, and shortens the time of optical path coupling between the optical processing devices 4 and the wavelength division multiplexing optical devices 2, thereby greatly improving the production efficiency of the wavelength division multiplexing optical communication device and further well meeting the requirements of the current consumption field on the wavelength division multiplexing optical communication device.
As an embodiment, the circuit board 1 may have two through holes (not shown in the figure) spaced apart from each other; at this time, the two positioning portions 52 may be connected to the wavelength division multiplexing optical device 2 through the two through holes, respectively.

Based on this, the wavelength division multiplexing optical device 2 may have two insertion portions 211 spaced apart from each other, and the two insertion portions 211 may be respectively inserted into and mated with the two insertion holes 521.
For this embodiment, when the optical processors 4 and the wavelength division multiplexing optical device 2 need to be optically coupled, the two positioning portions 52 in the positioning member 5 may first pass through the circuit board 1, and then the two insertion portions 211 in the wavelength division multiplexing optical device 2 may be respectively inserted into the two insertion holes 521 in the positioning member 5.
As another embodiment, an end of the positioning portion 52 away from the main body 51 may be formed with a plug portion (not shown) extending in the direction of the wavelength division multiplexing optical device 2, and the two plug portions may be used as reference points for attaching the respective optical processing devices 4 to the circuit board 1. For this purpose, the wavelength division multiplexing optical device 2 may have two insertion holes (not shown) spaced apart from each other, and the two insertion holes may be respectively inserted into and mated with the two insertion portions.
For this embodiment, when the optical processors 4 and the wavelength division multiplexing optical device 2 need to be optically coupled, the two positioning portions 52 in the positioning member 5 may first pass through the circuit board 1, and then the two plugging portions in the positioning member 5 may be plugged into the two jacks in the wavelength division multiplexing optical device 2, respectively.
In the above two embodiments, in order to improve the connection stability of the positioning member 5 and the wavelength division multiplexing optical device 2; the aperture of the jack 521 in the positioning member 5 may be reduced along the plugging direction of the plugging portion 211 in the wavelength division multiplexing optical device 2; based on this, the plugging portion 211 in the wavelength division multiplexing optical device 2 may be an elastic plugging portion, that is, the plugging portion 211 in the wavelength division multiplexing optical device 2 may be made of an elastic material, such as silicon gel, plastic, and the like. Correspondingly, the aperture of the jack in the wavelength division multiplexing optical device 2 may also be reduced along the plugging direction of the plugging part in the positioning element 5; based on this, the inserting part in the positioning element 5 may also be an elastic inserting part, that is, the inserting part in the positioning element 5 may also be made of an elastic material, such as silicone rubber, plastic, and the like.
It should be understood that the above-described embodiment is only 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 in the embodiment of the present invention; in this regard, a person skilled in the art can flexibly set the setting according to the actual application scenario on the basis of the embodiment of the present invention. The technical features related to the positioning portion 52 and the wavelength division multiplexing optical device 2 may include, but are not limited to, a specific form in which the positioning portion 52 penetrates through the circuit board 1 and a specific form in which the positioning portion 52 is connected to the wavelength division multiplexing optical device 2.

On this basis, the light emitted/received by the plurality of light processing devices 4 may have different wavelengths, the plurality of filters 22 may also have different wavelengths, and the wavelength of the light emitted/received by any one of the light processing devices 4 may be the same as the wavelength of the corresponding filter 22.
