[0056] In related technologies, the solution of connecting BOSA and fiber optic adapter through fiber optic cable separates BOSA and fiber optic adapter, which occupies a lot of space and is not conducive to product miniaturization design; moreover, it has high requirements for fiber optic cable winding, which is not conducive to product design layout planning; adding fiber optic cable will also lead to higher costs.

[0057] To solve the above problems, in related technologies, a positioning hole is set at one end of the fiber optic adapter, and after the BOSA is directly connected to the positioning hole, the BOSA and the fiber optic adapter are soldered onto the circuit board at the same time.

[0058] However, the fiber optic adapter in the relevant technology consists of an upper cover and a lower shell. The upper cover and lower shell split the positioning hole into two semicircles, which leads to a large cumulative deviation in manufacturing and assembly. After the BOSA and the fiber optic adapter are fixed on the circuit board, the BOSA and the fiber optic adapter are prone to center deviation, which affects the matching accuracy of the external connector and the BOSA, resulting in large optical loss.

[0059] In the optical device connector of this application embodiment, the connecting housing is an integral design, which reduces tolerance accumulation; the mounting through hole in the connecting housing can constrain the optical connecting axis of the optical component in the y and z directions; while the optical connecting axis is connected to the mounting through hole, the first flange of the optical connecting axis abuts against the first wall surface, and at the same time, the two ends of the limiting component abut against the first flange and the second flange respectively, so as to constrain the optical connecting axis of the optical component in the x direction; ensuring the assembly accuracy of the optical component and the connecting housing, improving the connection accuracy of the optical component and the external plug, and reducing optical loss.

The external plug 400 extends into the optical device connector through the opening and is connected to the optical connecting shaft 301.

[0100] In summary, this application provides an optical device connector and an optical communication system. The optical device connector includes a connecting housing 100 and a limiting component 200. The connecting housing 100 includes a first wall surface 101 and a second wall surface 105 opposite to each other along a first direction. The first wall surface 101 is provided with a mounting through hole 1011, which is configured to connect with the optical connecting shaft 301 of the optical component 300. The second wall surface 105 is provided with an opening configured to allow an external plug 400 to pass through, so that the external plug 400 extends into the connecting housing 100 and connects with the optical connecting shaft 301. The optical connecting shaft 301... The outer periphery of 1 is provided with a first flange 302 and a second flange 303 spaced apart along a first direction. The first flange 302 is close to the first wall surface 101 and has a first surface and a second surface opposite to each other along the first direction. The first surface abuts against the first wall surface 101. The second flange 303 has a third surface 3031, which is opposite to the second surface along the first direction. The limiting component 200 is sleeved on the outer periphery of the optical connecting shaft 301 and has a first limiting surface and a second limiting surface opposite to each other along the first direction. The first limiting surface abuts against the second surface, and the second limiting surface abuts against the third surface.

[0101] The connecting housing 100 is a one-piece design, reducing tolerance accumulation. The mounting through hole 1011 inside the connecting housing 100 can constrain the optical connecting shaft 301 of the optical component 300 in the y and z directions. While the optical connecting shaft 301 is connected to the mounting through hole 1011, the first flange 302 of the optical connecting shaft 301 abuts against the first wall surface 101. At the same time, the two ends of the limiting component 200 abut against the first flange 302 and the second flange 303 respectively, so as to constrain the optical connecting shaft 301 of the optical component 300 in the x direction. This ensures the assembly accuracy of the optical component 300 and the connecting housing 100, improves the connection accuracy of the optical component 300 and the external plug 400, and reduces optical loss.
