[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0017] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "install," "connect," "connect," and "assemble" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0018] Reference Figure 1-Figure 5 A high-speed optical module fiber optic MPO connector that is waterproof, vapor-proof, and scratch-resistant includes: a connecting end face 2, a fiber end face 3, a guide pin hole 4, and a boss 5; the connecting end face 2 is an inclined surface, the fiber end face 3 is located in the middle of the connecting end face 2, the guide pin holes 4 are located on both sides of the connecting end face 2, and the bosses 5 are located on both sides of the connecting end face 2 and are located around the guide pin hole 4. The height of the bosses 5 is no more than 50 μm.

[0019] The beveled design of the connection end face 2 helps reduce reflection loss of the optical signal while maintaining compatibility with existing standards. Placing the optical fiber end face 3 at the center of the connection end face 2 ensures efficient transmission of the optical signal and facilitates precise docking with other optical fiber components. The provision of a guide pin hole 4 for precise positioning with the MT patch cord ensures the accuracy and stability of the connection. The bosses 5 are positioned on both sides of the connection end face 2 and around the guide pin hole 4. When the high-speed optical module optical fiber MPO connector 1 is connected to the MT patch cord, the bosses 5 make contact first, preventing direct contact between the optical fiber end faces 3. This not only prevents the formation of moisture, but also avoids scratches or wear that may be caused by direct contact, thereby reducing jitter and bit errors during high-speed data transmission.

[0020] The function of the boss 5 is to prevent direct contact between the fiber end faces 3 of the optical fiber MPO connector and the MT patch cord. By providing the boss 5, the formation of moisture and scratches caused by direct contact between the fiber end faces 3 of the optical fiber MPO connector and the fiber end faces 3 of the MT patch cord are avoided. The height of the boss 5 is strictly controlled to a maximum of 50 μm to ensure that the transmission of the optical signal is not significantly affected. If the boss 5 is too high, the distance between the optical fiber end faces 3 may be too large, thereby increasing the attenuation of the optical signal. The height of 50 μm is a carefully designed and tested value that can effectively prevent moisture and wear without significantly increasing the attenuation of the optical signal.

[0021] In some embodiments, reference Figure 4 , the inclination angle of the connecting end face 2 is 6°-10°.

[0022] The 6°-10° tilt angle range provides a reasonable balance, effectively reducing reflections while not compromising the stability and reliability of the connection due to excessively large angles. When light is emitted from the fiber end face 3, if the end face is perpendicular, some of the light will be reflected back to the transmitting end, causing signal loss and interference. By designing the end face with an angle, the reflected light is directed sideways instead of back to the transmitting end, significantly reducing reflection losses and improving signal transmission quality.

[0023] In the description of the embodiments of the present invention, it should be understood that "-" represents a range between two values, and the range includes the endpoints. For example, "6°-10°" represents a range greater than or equal to 6° and less than or equal to 10°.

[0024] Preferably, the inclination angle of the connecting end face 2 is 8°.

[0025] The tilt angle is set to 8°, which is the common setting for APC connection surfaces. This ensures the compatibility of the high-speed optical module fiber optic MPO connector 1 across different devices and systems. This allows the high-speed optical module fiber optic MPO connector 1 to be used in a variety of application scenarios without worrying about compatibility issues.

[0026] In some embodiments, a high-speed optical module fiber optic MPO connector that is waterproof, vapor-proof, and scratch-resistant further includes a dust cover, which is arranged on the outside of the high-speed optical module fiber optic MPO connector 1 and is used to cover the connection end face 2.

[0027] The setting of the dust cover can, on the one hand, effectively prevent dust and other tiny particles from adhering to the optical fiber end face 3, which may affect the transmission quality of the optical signal and increase signal attenuation and bit error rate; on the other hand, it provides additional physical protection, reducing the physical damage such as collision and scratching that the connection end face 2 may suffer during transportation and installation, thereby extending the service life of the high-speed optical module optical fiber MPO connector 1.

[0028] In some embodiments, the high-speed optical module fiber optic MPO connector 1 is made of polytetrafluoroethylene.

[0029] Polytetrafluoroethylene (PTFE) is a material with excellent insulation properties that can effectively prevent current leakage and electromagnetic interference. In addition, PTFE has a very low coefficient of friction, which reduces resistance when plugging and unplugging the high-speed optical module fiber optic MPO connector 1, making the operation smoother.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
