Detailed Embodiments

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments; the components of the embodiments of the utility model described and shown in the drawings here can generally be arranged and designed in various different configurations.

[0018] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0019] Please refer to Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an MPO positive-negative attenuator, comprising an optical fiber array 100, an optical input end 200, an optical output end 300 and a housing; a metal joint 302 is provided on the optical output end 300, and the metal joint 302 is connected to the optical output end 300 through a through hole 301; the optical fiber array 100 is arranged inside the housing; two ends of the optical fiber array 100 are respectively connected to the optical input end 200 and the optical output end 300; the housing is located between the optical input end 200 and the optical output end 300; the optical input end 200 and the optical output end 300 are movably connected to the housing through a spring 600, and pass through both ends of the housing.

[0020] It should be noted that the optical fiber array 100 is configured with 12 or 24 cores; specifically, the 12-core optical fiber array 100 has one 40G Ethernet application: the 40G Ethernet specification usually requires 8-core interconnection, with a 4-transmit 4-receive configuration, and the 12-core optical cable wiring solution can meet this requirement, in which the middle 4-core optical fiber remains idle; second, modularity and flexibility: the 12-core optical fiber array provides a better modular design, which is convenient for network expansion and upgrading, while maintaining a high optical fiber utilization rate.

[0021] Furthermore, the 24-core fiber array 100 has two advantages: 1. 100G Ethernet application: 100G Ethernet solution specifies the use of 24 optical fibers, usually divided into two 12-core arrays, one dedicated to sending and the other dedicated to receiving, to support higher data transmission rates; 2. Higher data transmission efficiency: 24-core fiber arrays can provide higher fiber capacity and are suitable for scenarios that require more fiber connections and larger data transmission volumes, such as data centers and large-scale communication networks. The fiber array is set to 12 or 24 cores because these configurations can meet the needs of different data communication rates and application scenarios; 12-core and 24-core MPO connectors are currently common high-density fiber connection solutions in data centers and high-speed communication networks.

[0022] As a preferred implementation, the optical fiber array 100, the light output end 200 and the light output end 300 are integrally arranged; specifically, by integrating the optical fiber array 100, the input end and the output end into one component, the number of connectors can be reduced, thereby reducing signal attenuation and reflection at the connection point, and improving the overall performance of the system; the integrated design reduces connector failures caused by multiple plugging and unplugging or external factors, and enhances the stability and durability of the system; the use of a single integrated component simplifies the installation and maintenance process of the system, reduces the possibility of errors, and also reduces maintenance and replacement costs.

[0023] As a preferred embodiment, the shell includes a shell 400 and a shell cover 500 arranged at both ends of the shell 400; a texture elastic piece 501 is provided on the shell cover 500, and the texture elastic piece 501 is arranged on the shell cover 500 through a protruding block 511 outside the shell cover 500; the shell 400 is internally penetrated and arranged on the optical fiber array 100; the shell cover 500 is internally connected to the light input end 200 and the light output end 300 through a spring 600, and the light input end 200 and the light output end 300 pass through the shell cover 500; specifically, the shell 400 constitutes the main structure of the entire device, which is used to accommodate and protect internal components; the shell cover 500 is arranged at both ends of the shell 400 and is connected to the shell 400 by a snap-fit ​​method; the texture elastic piece 501 and the protruding block 511 on the shell cover 500 increase the friction during operation, so that the user has a better grip and operation experience when inserting or pulling out the optical fiber.

[0024] Furthermore, the textured elastic member 501 can not only provide additional gripping force, but also play a certain buffering role when the device is subjected to a slight collision, thereby protecting the internal components.

[0025] As a preferred embodiment, the shell cover 500 is provided with a dust cap 502 at one end away from the housing 400, and the dust cap 502 is snap-connected to the shell cover 500; specifically, the dust cap 502 is provided with two shell covers 500 respectively connected to the two sides, and the main function of the dust cap 502 is to protect the end face of the optical fiber connector from contamination. The end face of the optical fiber is very delicate, and any tiny dust or moisture may cause signal attenuation or interruption, affecting the communication quality. Therefore, when the device is not in use, it is necessary to use a dust cap to seal the optical fiber interface in time; the snap-on connection between the dust cap 502 and the shell cover 500 is a fast and reliable fixing method; the snap-on design allows the user to easily install or remove the dust cap 502 without using additional tools. At the same time, the tightness of the snap also ensures the stability of the dust cap 502 during transportation or storage to avoid accidental falling off.

[0026] As a preferred implementation, specifically, through the connection method of the metal joint 302 and the through hole 301, the stable fixation of the light output end 300 can be ensured, avoiding the loosening of the fiber optic connection caused by vibration or external force, thereby improving the stability and reliability of the connection. The use of its metal joint 302 can not only enhance the mechanical strength of the fiber optic connector but also improve its durability, enabling the MPO male-female attenuator to maintain good performance in various environments. It can ensure the precise alignment of 12-core or 24-core optical fibers at the input end and the output end, reduce the loss during signal transmission, and improve the transmission efficiency of optical signals. The light input end 200 and the light output end 300 are movably connected through a spring 600, making it more convenient to maintain or replace the optical fiber. The setting of its outer shell can effectively protect the internal optical fiber from the influence of the external environment (such as dust, humidity), and improve the environmental adaptability of the MPO male-female attenuator. Through the fiber optic array 100 and the outer shell structure, the attenuation of the signal during transmission can be effectively reduced, and the transmission quality of the signal can be improved. At the same time, since the MPO male-female attenuator is composed of 12-core or 24-core optical fibers, it is very suitable for high-density fiber optic connection scenarios such as data centers and communication networks, and can effectively reduce the space occupation and improve the integration of the device.

[0027] Furthermore, the present utility model provides an MPO male-female attenuator, which not only improves the stability of the connection and the signal transmission quality but also enhances the durability and environmental adaptability of the device. At the same time, it supports high-density connections and is an indispensable component in modern fiber optic communication systems.

[0028] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or terminal device including the said element.

[0029] The above has introduced in detail a kind of MPO male-female attenuator provided by the present utility model. Specific examples are used in this article to expound the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
