[0004] In high-density applications, when operation and maintenance personnel plug in or install MPO connectors, they may inadvertently unlock adjacent MPO connectors. If such accidental unlocking cannot be discovered and handled in a timely manner, it will cause anomalies in a normally operating link, bringing great trouble to operation and maintenance.

[0018] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0019] Refer to Figure 1 , which shows a schematic structural view of an MPO loopback device of the present utility model. Specifically, it may include: a connector housing 1, an optical fiber cluster 2, an optical fiber socket 3, a pin 4, a spring 5, and a buffer sleeve 6; one end of the optical fiber cluster 2 is connected to the positive pole of the optical fiber socket 3, and the other end is connected to the negative pole of the optical fiber socket 3; the pin 4 is snap-connected to the optical fiber socket 3 and is fixedly connected to both ends of the optical fiber cluster 2; the spring 5 is sleeved on the annular circuit formed by the connection of the optical fiber cluster 2 and the optical fiber socket 3; the buffer sleeve 6 is wrapped outside the optical fiber socket 3 and the pin 4; the optical fiber cluster 2 and the spring 5 are arranged inside the connector housing 1; the detachable connector housing 1 and the buffer sleeve 6 are snap-connected.

[0020] It should be noted that the optical fiber cluster 2 is composed of multiple optical fibers arranged side by side. An optical fiber, whose full name is optical fiber wire or optical fiber cable, is a fiber made of glass or plastic and is used to transmit optical signals. The arrangement of multiple optical fibers side by side has the following advantages. The MPO loop connector allows multiple optical fibers to be connected in a compact space, usually 12-core or 24-core. This high-density connection reduces the space requirements of the equipment and is particularly suitable for environments with high space requirements such as data centers. Secondly, the multi-fiber connection reduces the number of connection points, thereby reducing the complexity of management and maintenance. Multiple optical fibers working in parallel can significantly increase the data transmission rate. For example, in 40G and 100G Ethernet, multiple optical fibers are usually used for parallel transmission to achieve high speed. Compared with multiple single-fiber connectors, the MPO connector reduces the number of connection points, thereby reducing the overall insertion loss and return loss and improving the signal quality.

[0021] Furthermore, the optical fiber cluster 2 is composed of several optical fibers arranged side by side, and the connection points at one end and the other end of the several optical fibers are located on the same straight line, so that the optical fiber cluster 2 forms a shape similar to an "O" after connection. The inner diameter of this shape increases from the connection point to the part far away from the connection point, which is also a ring circuit. Due to the material of the optical fiber itself, the formed optical fiber cluster 2 also has a certain elasticity. Because the optical fibers are bonded together with glue near the connection point, and since it is far from the deformed part, the elastic force is small, and the glue cancels out the elastic force of the optical fiber cluster 2 itself. This area is denoted as the first area. The part where no glue is set, that is, the area with a larger inner diameter in the ring circuit, is denoted as the second area, where the deformation is large and the elastic potential energy is also large. The spring 5 is sleeved on the ring circuit formed by the connection of the optical fiber cluster 2 and the optical fiber socket 3. Specifically, it is set near the connection point of the ring circuit, that is, the spring 5 is in the first area of the optical fiber cluster 2. The elastic force in the second area makes the spring 5 fixed in this position.

[0022] Referring to Figure 1 , a schematic structural diagram of an MPO loop connector of the present invention is shown. Specifically, it may include: a connector housing 1, an optical fiber cluster 2, an optical fiber socket 3, a pin 4, a spring 5, and a buffer sleeve 6. One end of the optical fiber cluster 2 is connected to the positive pole of the optical fiber socket 3, and the other end is connected to the negative pole of the optical fiber socket 3. The pin 4 is snap-connected to the optical fiber socket 3 and fixedly connected to both ends of the optical fiber cluster 2. The spring 5 is sleeved on the ring circuit formed by the connection of the optical fiber cluster 2 and the optical fiber socket 3. The buffer sleeve 6 is wrapped outside the optical fiber socket 3 and the pin 4. The optical fiber cluster 2 and the spring 5 are arranged inside the connector housing 1. The detachable connector housing 1 and the buffer sleeve 6 are snap-connected.

[0023] Further, the MPO circulator further includes a protective cap 7; the protective cap 7 is snap-connected to the connector housing 1. It should be noted that the protective cap is used to protect the connection port of the MPO circulator from damage and prevent dust from entering, which may affect the contact effect.

[0024] Further, the connector housing 1 is a housing formed by snap-connecting a pair of half-shells. It should be noted that by setting two parts for assembly, it is convenient to install the annular loop formed by connecting the optical fiber cluster 2 and the optical fiber socket 3. Further, the width of the housing gradually decreases from one end to the other end.

[0025] Further, the buffer sleeve 6 further includes an elastic member; the elastic member is slidably connected to the buffer sleeve 6. It should be noted that the elastic member is to avoid hard connection when the MPO circulator is connected. The force applied to the buffer sleeve first causes the elastic member to slide, and the damage caused by frictional sliding is much smaller than the force reaching the MPO circulator, thus avoiding damage to the connection port of the MPO circulator due to excessive force.

[0026] Further, the elastic member is made of rubber material.

[0027] Further, preferably, the diameter of the optical fiber is 3.0 mm.

[0028] Further, the connector housing 1, the buffer sleeve 6, and the protective sleeve 7 are all covered with a highly environmentally friendly PVC material outer skin, which has strong flame retardancy and tensile properties. Preferably, different chemical modifications and material ratios are used in the PVC material to improve its flame retardancy and tensile properties.

[0029] 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 "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or terminal device comprising the element.

[0030] The above has introduced in detail a kind of MPO loop device provided by the present utility model. Specific examples are used in this article to elaborate on 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.
