Description

Technical Field

[0001] This utility model relates to the field of MT ferrule technology, specifically to a high-power MT ferrule. Background Technology

[0002] MT ferrules are the core components of multi-core connectors (MPO connectors), and driven by the rapid development of fiber optic communication and data centers, they have become a key component in high-speed optical communication modules. With the widespread application of optical communication modules in data centers and optical communication networks, the market demand for MT ferrules and fiber optic assemblies, as homogeneous density connection components, continues to rise.

[0003] Currently, most MT ferrules are made of plastic materials, such as polyphenylene sulfide (PPS) mixed with glass fiber. However, in high-power applications, after repeated insertion and removal of optical fibers, the end face and surrounding area of ​​the plastic MT ferrule are prone to ablation due to the concentration of optical energy.

[0004] A current type of MT ferrule uses a metal film on its body as a protective layer. This metal film serves both reflective and heat-dissipating functions, helping to reduce the absorption of optical power and prevent heat from accumulating locally on the MT end face, thus protecting the ferrule. However, this metal film only protects the ferrule body; during optical insertion and removal, high-power reflected light can still damage the test fiber optic line. Utility Model Content

[0005] The purpose of this invention is to provide a high-power MT ferrule that can be plugged in with light without being burned.

[0006] To achieve the above objectives, this utility model provides a high-power MT ferrule, comprising a ferrule body, a glass body, and multiple optical fibers. The ferrule body has multiple first optical fiber jacks, the glass body is disposed at the end of the ferrule body, and the glass body has multiple second optical fiber jacks. The multiple second optical fiber jacks are arranged and connected to the multiple first optical fiber jacks one by one, and the bare fiber portion of the optical fiber passes through the first optical fiber jack and is disposed in the second optical fiber jack.

[0007] As can be seen from the above scheme, by setting a glass body at the end of the ferrule body, high-power light can be scattered during the insertion and removal of the optical fiber, so as to avoid excessive concentration of high-power light, which can protect the ferrule body and avoid burning the test optical fiber line.

[0008] A further option is to provide a first adhesive part at one end of the ferrule body and a second adhesive part at one end of the glass body, with the first adhesive part and the second adhesive part being fixed together by adhesive bonding.

[0009] A further option is to have a glass thickness of 1mm to 3mm.

[0010] A further design is that the second fiber optic jack includes a horn-shaped section and a straight section, with the two ends of the horn-shaped section connected to the first fiber optic jack and the straight section, respectively.

[0011] As can be seen from the above scheme, after the bare fiber portion passes through the first fiber optic jack, it is precisely inserted into the straight jack section under the guidance of the horn-hole section, ensuring high-precision positioning of the bare fiber portion in the second fiber optic jack.

[0012] A further design involves providing a bevel at the end of the glass body away from the ferrule body, through which the second fiber optic jack extends.

[0013] A further option is to fix the bare fiber portion in the first and second fiber optic jacks by bonding, with the end face of the bare fiber portion flush with the bevel.

[0014] A further option is that the ferrule body has a first positioning hole, and the glass body has a second positioning hole, with the second positioning hole being coaxially arranged and connected to the first positioning hole.

[0015] As can be seen from the above scheme, when fixing the glass body to the ferrule body, positioning can be achieved by using positioning pins that are simultaneously inserted into the first positioning hole and the second positioning hole, so as to ensure that the glass body and the ferrule body are accurately aligned.

[0016] A further option is that the end of the second positioning hole and the end of the second fiber optic jack are in the same plane.

[0017] A further embodiment is that the center of the first positioning hole and the center of the first fiber optic jack are both located in the first plane, and the center of the second positioning hole and the center of the second fiber optic jack are both located in the second plane, with the first plane and the second plane being coplanar.

[0018] A further option is to make the ferrule body a plastic body. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0025] See Figure 1 and Figure 2 This embodiment provides a high-power MT ferrule, which includes a ferrule body 1, a glass body 2, and multiple optical fibers 3.

[0026] The ferrule body 1 has multiple first fiber optic jacks 11 and two first positioning holes 12. The number of first fiber optic jacks 11 is equal to the number of optical fibers 3. The multiple first fiber optic jacks 11 are located in the middle of the ferrule body 1, and the first positioning holes 12 are located on both sides of the ferrule body 1; preferably, the multiple first fiber optic jacks 11 are arranged along a straight line between the two first positioning holes 12, and the center of the first positioning hole 12 and the center of the first fiber optic jack 11 are both located in a first plane.

[0027] The glass body 2 is disposed at the front end of the insert body 1. A first adhesive portion is provided at one end of the insert body 1, and a second adhesive portion is provided at one end of the glass body 2. The first adhesive portion and the second adhesive portion are fixed together by adhesive bonding. The first adhesive portion and the second adhesive portion can be surface-to-surface or have a concave-convex fit; no limitation is imposed here. At the end of the glass body 2 away from the insert body 1, a slope 23 and a plane 24 are provided. The plane 24 is perpendicular to the first sidewall of the glass body 2. One side of the slope 23 is connected to the plane 24, and the other side of the slope 23 extends obliquely toward the second sidewall of the glass body 2. The first sidewall and the second sidewall are disposed opposite each other. The glass body 2 has multiple second fiber optic jacks 21 and two second positioning holes 22, both of which extend through the inclined surface 23. The center of the second positioning hole 22 and the center of the second fiber optic jack 21 are both located in a second plane, which is coplanar with the first plane. The multiple second fiber optic jacks 21 are correspondingly arranged and connected to the multiple first fiber optic jacks 11. The bare fiber portion 31 of the fiber optic cable 3 passes through the first fiber optic jack 11 and is positioned within the second fiber optic jack 21. The bare fiber portion 31 of the fiber optic cable 3 is fixed in place by adhesive bonding within the first fiber optic jack 11 and the second fiber optic jack 21, with the end face of the bare fiber portion 31 flush with the inclined surface 23. The second positioning holes 22 are coaxially arranged and connected to the first positioning holes 12. Precise alignment of the ferrule body 1 and the glass body 2 is achieved by positioning posts (not shown in the figure) inserted into the first positioning holes 12 and the second positioning holes 22, facilitating precise bonding and fixing. After fixing, the positioning posts can be removed or retained; no restriction is imposed.

[0028] The thickness of the glass body 2 is 1 mm to 3 mm.

[0029] During insertion and removal with light, the plane 24 and the inclined surface 23 at the front end of the glass body 2 can reflect high-power light at different angles, avoiding excessive concentration of reflected light that could cause the MT ferrule end face to be burned.

[0030] Furthermore, the glass body 2, made of glass material, exhibits transmission phenomena, including forward scattering, also known as diffuse transmission. Forward scattering is a non-directional refraction phenomenon caused by the microscopic unevenness of the glass surface, which causes light to propagate at multiple angles during transmission. This embodiment utilizes this characteristic of the glass body 2 to scatter high-power light, preventing excessive concentration of high-power light from burning the MT ferrule end face and the test fiber optic cable.

[0031] The insert body 1 is made of plastic.

[0032] See Figures 3 to 5 The second fiber optic jack 21 includes a flared end 211 and a straight end 212. The larger diameter end of the flared end 211 communicates with the first fiber optic jack 11, and the wall of the flared end 211 smoothly transitions with the wall of the first fiber optic jack 11. The smaller diameter end of the flared end 211 communicates with the straight end 212, and the wall of the flared end 211 smoothly transitions with the wall of the straight end 212. The diameter of the straight end 212 is greater than or slightly equal to the outer diameter of the bare fiber portion 31 of the optical fiber 3.

[0033] In summary, by providing a glass body 2 at the end of the ferrule body 1, this utility model can scatter high-power light during the insertion and removal process, thereby avoiding excessive concentration of high-power light. This not only protects the ferrule body 1 but also prevents the test fiber optic line from being burned.

[0034] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
