[0002] An optical fiber attenuator is an optical device that reduces the energy of an optical signal. It is used to attenuate the input optical power and avoid distortion in the optical receiver caused by excessive input optical power.

[0003] Currently, most of the attenuators on the market are LC male and female attenuators, and their tailstocks adopt a hexagonal and beveled design. The front sleeve also adopts this design, and the two work together to limit the position of the tailstock.

[0004] However, due to the large number of components, traditional attenuators are prone to failure during long-term use, affecting the stability and reliability of the equipment. Utility Model Content

[0005] In view of the above problems, this utility model is proposed to provide a MU attenuator that overcomes or at least partially solves the above problems.

[0006] To address the aforementioned issues, this utility model discloses a MU attenuator, comprising: a ceramic ferrule, a spring, a front sleeve, a rear sleeve, and a housing; the front sleeve and the rear sleeve are snap-fitted together; the ceramic ferrule is disposed within the rear sleeve, and one end of the ceramic ferrule passing through the spring is located at the connection between the front sleeve and the rear sleeve; the front sleeve and the rear sleeve are respectively snap-fitted together with the housing.

[0007] Furthermore, the outer shell is integrally injection molded.

[0008] Furthermore, the MU attenuator also includes a front dust cover; the front dust cover is embedded in the front sleeve.

[0009] Furthermore, the MU attenuator also includes a rear dust cover; the rear dust cover is embedded in the rear sleeve.

[0010] Furthermore, a groove is provided at one end of the outer shell that connects to the rear sleeve; the rear sleeve is snapped together with the outer shell through the groove.

[0011] This utility model has the following advantages:

[0012] By incorporating a spring and a ceramic ferrule, the spring's elasticity and the friction generated by contact ensure a firm connection between the ceramic ferrule and the rear sleeve, resulting in a more stable connection, significantly extended service life, and reduced susceptibility to failure.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1 This diagram illustrates the structure of a MU attenuator according to the present invention. Specifically, it includes: a ceramic ferrule 1, a spring 2, a front sleeve 3, a rear sleeve 4, and a housing 5. The front sleeve 3 and the rear sleeve 4 are snap-fitted together. The ceramic ferrule 1 is disposed within the rear sleeve 4, with one end of the ceramic ferrule 1 passing through the spring 2 and positioned at the connection between the front sleeve 3 and the rear sleeve 4. The front sleeve 3 and the rear sleeve 4 are respectively snap-fitted together with the housing 5. It should be noted that the rear sleeve 4 has a circular through-hole, and the ceramic ferrule 1 is disposed within this through-hole. A cylinder is positioned at the center of one end of the front sleeve 3, the diameter of the cylinder's cross-section being the same as the diameter of the circular through-hole. The cylinder is inserted into the rear sleeve 4 to complete the snap-fit ​​connection, fixing the front sleeve 3 and the rear sleeve 4. One end of the ceramic ferrule 1 passes through the spring 2 and abuts against the cylinder. Under the action of the spring's elasticity and friction, the ceramic ferrule 1 and the cylinder are fixed.

[0018] Furthermore, refer to Figure 2 The diagram shows a structural schematic of an embodiment of the MU attenuator of this utility model, wherein the outer shell 5 is integrally injection molded. It should be noted that the integrally injection molded outer shell 5 is formed by molding two or more materials (usually soft and hard materials) in one step during the injection molding process to form an integral structure. The soft material can provide a good feel, making the product more comfortable and easy to use. Furthermore, anti-slip grooves are provided on the outer shell 5 to facilitate the application of force for installation or removal.

[0019] Furthermore, the MU attenuator also includes a front dust cover 6; the front dust cover 6 is embedded in the front sleeve 3; the MU attenuator also includes a rear dust cover 7; the rear dust cover 7 is embedded in the rear sleeve 4. It should be noted that when the ceramic ferrule 1 is installed in the cylinder where the front sleeve 3 and the rear sleeve 4 are snap-connected, the end of the ceramic ferrule 1 closest to the front sleeve 3 is the male end, and the end closest to the rear sleeve 4 is the female end. The front dust cover 6 is installed on the male end, and the rear dust cover 7 is installed on the female end. Both the male and female ends are connection ports used for connection.

[0020] Furthermore, a groove is provided at one end of the outer shell 5 that connects to the rear sleeve 4; the rear sleeve 4 is snap-fitted to the outer shell 5 through the groove.

[0021] Furthermore, it is more preferred that the ceramic ferrule 1 is made of alumina, which has the advantages of good electrical insulation properties, high mechanical strength, wear resistance, and relatively low cost.

[0022] Working principle: One end of the ceramic ferrule 1 passes through the spring 3 and abuts against the front sleeve 3, while the other end extends a predetermined distance from the rear sleeve 4. The ceramic ferrule 1 is located inside the rear sleeve 4. The front sleeve 3 and the rear sleeve 4 are snap-fitted together. After assembly, the front dust cover 6 and the rear dust cover 7 are respectively fitted onto the connection port of the front sleeve 3 and the connection port of the rear sleeve 4. When two attenuators need to be assembled together, the front dust cover 6 and the rear dust cover 7 are pulled out, and the rear sleeve 4 of the other attenuator is inserted into the front sleeve 3 of the first attenuator. The exposed ceramic ferrule 1 of the rear sleeve 4 of the other attenuator is inserted into the front sleeve 3 of the first attenuator, thus completing the assembly of the two attenuators.

[0023] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.
