[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following combines specific embodiments and drawings to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present utility model.

[0022] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific Embodiment 1:

[0024] Referring to Figures 1-4 , a multi-channel optical demultiplexer includes a demultiplexer body 1. A connection block 4 is provided on the surface of the demultiplexer body 1. A connection groove 10 is opened on the side surface of the connection block 4. The connection grooves 10 are arranged in a linear array on the side surface of the connection block 4. The shape of the connection groove 10 is adapted to the fixing block 13. Through the setting of the connection groove 10, it is convenient to place the first connection optical fiber line 11. At the same time, in cooperation with the fixing block 13, it is convenient to closely fit the first connection optical fiber line 11 and the second connection optical fiber line 14. A protective cover 5 is provided on the surface of the connection groove 10. Through the setting of the protective cover 5, when the first connection optical fiber line 11 is not needed, the protective cover 5 covers and protects the connection groove 10 to prevent the first connection optical fiber line 11 from being exposed to the external environment. The first connection optical fiber line 11 penetrates through the surface of the connection groove 10. An installation block 7 is provided on the surface of the demultiplexer body 1. Mounting plates 9 are provided on the side surfaces of the installation block 7 and the connection block 4, and mounting bolts are provided on the surfaces of the mounting plates 9. Through the setting of the mounting plates 9 and the mounting bolts, it is convenient to mount the installation block 7 and the connection block 4 on the surface of the demultiplexer body 1.

[0025] The surface of the mounting block 7 is provided with a slot 8, and the surface of the slot 8 is provided with a plug 12. The shapes of the slot 8 and the plug 12 are both T-shaped, and the shape and position of the slot 8 are adapted to the plug 12. Through the settings of the slot 8 and the plug 12, it is convenient to insert the mounting seat 6 into the mounting block 7, so that the second connecting optical fiber line 14 in the mounting seat 6 and the first connecting optical fiber line 11 in the connecting block 4 are closely attached. There is friction between the plug 8 and the slot 12 to prevent the mounting seat 6 from sliding in the mounting block 7 after installation. The mounting seat 6 is provided on the surface of the plug 12, and the position of the mounting seat 6 corresponds to the connecting groove 10. A fixing block 13 is provided on the side of the mounting seat 6, and the second connecting optical fiber line 14 penetrates through the surface of the fixing block 13. The shape and position of the first connecting optical fiber line 11 correspond to those of the second connecting optical fiber line 14. The second connecting optical fiber line 14 penetrates through the mounting seat 6 and the fixing block 13 and is respectively connected to the output optical fiber 3. Through the close attachment of the first connecting optical fiber line 11 and the second connecting optical fiber line 14, the transmission of optical signals is realized, and the optical signals of different wavelengths are respectively transmitted out through the output optical fiber 3 on the mounting seat 6 through the second connecting optical fiber line 14. The output optical fibers 3 are equidistantly arranged on the side of the mounting seat 6. Through the setting of the output optical fiber 3, as the outlet of the optical signal, each output optical fiber 3 corresponds to the optical signal of one channel, and the demultiplexed optical signal is output to the subsequent device or system. The side of the multiplexer body 1 is communicated with an input optical fiber 2, and the input optical fiber 2 is the inlet of the optical signal and is responsible for introducing the optical signal to be demultiplexed into the multiplexer body 1. The output optical fibers 3 are arranged in a linear array on the side of the multiplexer body 1.

[0026] When the number of output optical fibers 3 of the multiplexer body 1 is insufficient to carry the transmission of optical signals of diverse wavelengths, the protective cover 5 installed on the surface of the connecting groove 10 is removed, and the mounting seat 6 is accurately inserted into the mounting block 7 through the plug 12 provided at the bottom, so that one end of the mounting seat 6 firmly abuts against the connecting block 4. At the same time, the fixing block 13 is inserted into the connecting groove 10 smoothly, which not only stabilizes the overall structure, but also enables the first connecting optical fiber line 11 and the second connecting optical fiber line 14 to be closely attached, so that the optical signals of different wavelengths can be seamlessly transmitted through these two optical fiber lines, and the optical signals of different wavelengths are respectively transmitted out through the output optical fiber 3 on the mounting seat 6 through the second connecting optical fiber line 14. The input port of the multiplexer body 1 receives the composite optical signal from the input optical fiber 2, and this signal contains optical components of multiple different wavelengths. Inside the multiplexer body 1, through the action of dispersion elements (such as gratings, arrayed waveguide gratings, etc.), the optical signals of different wavelengths are separated and guided to different output ports. Each output port only outputs the optical signal of a specific wavelength, and the demultiplexed optical signal is output to the subsequent device or system through the output optical fiber 3, thus realizing the demultiplexing of optical signals. Specific Embodiment Two:

[0028] On the premise of meeting the above structure, the multiple connection slots 10 and the first connecting optical fiber line 11 skillfully arranged on the connection block 4 endow the multi-channel optical demultiplexer with unprecedented flexibility and expandability, allowing operators to install multiple output modules at one time, and personnel can flexibly adjust and set the specific number of connection slots 10 according to actual transmission requirements, so as to accurately match the demultiplexing requirements of optical signals, ensuring the optimal operation of the system and the efficient utilization of resources.

[0029] To sum up:

[0030] 1. By adopting the slot 8, the plug 12, the first connecting optical fiber line 11 and the second connecting optical fiber line 14, when the number of output optical fibers 3 of the multiplexer body 1 is insufficient to carry the transmission of diverse wavelength optical signals, the protective cover 5 installed on the surface of the connection slot 10 is removed, and the mounting seat 6 is accurately inserted into the mounting block 7 through the plug 12 arranged at the bottom, so that one end of the mounting seat 6 firmly abuts against the connection block 4. At the same time, the fixing block 13 is inserted into the connection slot 10 along the way, which not only stabilizes the overall structure, but also enables the first connecting optical fiber line 11 and the second connecting optical fiber line 14 to be closely attached, so that optical signals of different wavelengths can be seamlessly transmitted through these two optical fiber lines without additionally increasing the number of multiplexer bodies 1, solving the problem of insufficient number of output optical fibers 3.

[0031] It saves space resources and promotes the compactness and efficiency of the overall device.
