Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber communication, and in particular to an optical splitter capable of realizing non-uniform ratio transmission of multi-mode light. Background Art

[0002] In optical communication networks, splitters are key nodes that connect optical fiber links. Their maintenance efficiency and ease of assembly and disassembly are crucial to ensuring network stability and reducing operating costs. Currently, splitter designs on the market generally have problems such as cumbersome assembly and disassembly steps, the need for professional tools, and long component replacement times. These problems not only increase the workload of maintenance personnel, but may also cause equipment damage due to improper operation, further increasing maintenance costs and downtime.

[0003] In high-precision applications such as optical communications and optical sensing, the working stability and reliability of the spectrometer are directly related to the accuracy of data transmission and the overall performance of the system. However, existing spectrometers often face many challenges in complex and changing working environments, such as temperature fluctuations, mechanical vibrations, and electromagnetic interference, all of which may have adverse effects on the internal structure and optical performance of the spectrometer.

[0004] With the continuous development of optical communication technology and the continuous expansion of application fields, the functional requirements for splitters are becoming increasingly diverse. Most traditional splitters can only achieve equal or fixed ratio distribution of optical signals, and cannot meet the flexible control requirements of optical signal transmission ratio in complex application scenarios. Especially in multi-mode optical communication systems that require precise adjustment of optical signal strength, traditional splitters are unable to cope with the situation.

DETAILED DESCRIPTION

[0028] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0029] Example

[0030] like Figure 1-Figure 6 As shown, an embodiment of the present invention proposes a splitter that can realize non-uniform transmission of multi-mode light. In order to realize the quick disassembly and assembly function of the splitter, a rectangular groove 4 is designed on the side of the splitter housing 1, and the groove is used to receive the plug-in piece 6 at the lower end of the housing cover 2. A limiting socket 5 is provided on the end wall of the rectangular groove 4, and a sliding groove 7 is designed on the plug-in piece 6, and a lap slider 12 is slidably connected in the groove. A limiting plug rod 13 is fixedly connected to one end of the lap slider 12, and the plug rod can be inserted into the limiting socket 5, so as to fix the position of the plug-in piece 6 and the rectangular groove 4. For the convenience of operation, a detent groove 14 is also provided on the lap slider 12, and the user can move the lap slider 12 by detent. In addition, the sliding groove 7 and the lap slider 12 are automatically reset by a reset component such as a spring.

[0031] In order to stabilize the planar waveguide type splitter electric board 3, we installed a rubber pad column 15 on the inner bottom wall of the splitter housing 1, and fixed a plug rod 16 on its upper end. The diagonal part of the electric board 3 is designed with a sleeve ring piece 17, which is sleeved on the plug rod 16 and placed on the upper end surface of the rubber pad column 15; this padding structure effectively reduces the vibration and displacement of the electric board 3, and improves its working stability and life; the design size of the plug piece 6 is adapted to the opening size of the rectangular groove 4, ensuring that the plug piece 6 can be tightly and stably inserted into the rectangular groove 4, so as to achieve a firm connection between the housing cover 2 and the splitter housing 1.

[0032] Furthermore, in order to limit the upward movement of the electric board 3, we installed a vertical fixing block 18 on the inner bottom wall of the splitter housing 1, and opened a rectangular through slot 19 thereon. A rectangular limiting rod 20 is slidably inserted in the rectangular through slot 19, and one end of the limiting rod is provided with an arc slope 21. When the abutting rod 22 at the lower end of the housing cover 2 contacts the arc slope 21, it will push the rectangular limiting rod 20 to move in the through slot until it abuts against the top of the electric board 3, limiting its upward movement. At the same time, the rectangular through slot 19 and the rectangular limiting rod 20 are reset by the reset component 2; the stabilizing component effectively prevents the electric board 3 from moving upward due to vibration or other external forces, ensuring the normal operation of the splitter; the lower end surface of the rectangular limiting rod 20 is designed to be flush with the upper end surface of the planar waveguide type splitter electric board 3 after it is placed. In this way, when the rectangular limiting rod 20 moves to the top of the electric board 3 under the action of the abutting rod 22, it can tightly abut against the electric board 3 to prevent it from moving upward.

[0033] Among them, the structure of the reset component 2 is similar to that of the reset component 1, but it is installed in the rectangular through groove 19. A fixed rod 24 is provided in the strip groove 23, and a spring 25 is sleeved thereon. The sliding sleeve block 26 is slidably sleeved on the fixed rod 24 and fixedly connected to the side of the rectangular limit rod 20. When the rectangular limit rod 20 is pushed and moved by the abutting rod 22, the spring 25 will be compressed; when the abutting rod 22 is moved away, the elastic force of the spring 25 will reset the rectangular limit rod 20; the reset component 2 ensures that the rectangular limit rod 20 can automatically return to its original position after moving, thereby maintaining a stable restriction on the electric board 3; the installation method of the spring 25 is similar to that of the spring 10, but one end of the spring 25 is fixed on the end wall of the strip groove 23, and the other end is fixed on the surface of one end of the sliding sleeve block 26. When the second sliding sleeve block 26 drives the rectangular limiting rod 20 to move, the second spring 25 will be compressed; when the abutting rod 22 moves away, the elastic force of the second spring 25 will push the second sliding sleeve block 26 and the rectangular limiting rod 20 to return to their original positions.

[0034] Furthermore, the reset component 1 includes a strip-shaped placement groove 8 opened on the inner side wall of the sliding groove 7, in which a fixing rod 19 is provided and a spring 10 is sleeved. The sliding sleeve block 11 is slidably sleeved on the fixing rod 9 and is fixedly connected to the side of the overlapping slider 12. When the overlapping slider 12 is triggered and moved, the spring 10 will be compressed; after being released, the elastic force of the spring 10 will reset the overlapping slider 12; the reset component 1 ensures that the overlapping slider 12 can automatically return to its original position after moving, thereby maintaining the stable insertion state of the limit plug 13.

[0035] One end of the spring 10 is fixed on the end wall of the strip-shaped placement groove 8, and the other end is fixed on the end surface of the sliding sleeve 11. When the sliding sleeve 11 drives the overlapping slider 12 to move, the spring 10 will be compressed; when the external force disappears, the elastic force of the spring 10 will push the sliding sleeve 11 and the overlapping slider 12 to reset; the design of the spring 10 ensures the automatic reset function of the overlapping slider 12.
