[0002] The current OSA products (single-fiber bidirectional transceiver integrated components) need to control the processing accuracy of the single-fiber bidirectional transceiver integrated components within certain specifications during coupling welding because of the large specifications of the ferrule itself. In order to avoid reflection or refraction inside the optical fiber, the single-fiber bidirectional transceiver integrated components generally have internal holes tilted, that is, the ferrule end and the fiber core insertion end are not in a horizontal state, making the processing technology control of the single-fiber bidirectional transceiver integrated components difficult. At the same time, due to the tilted hole setting inside the single-fiber bidirectional transceiver integrated components, grinding equipment with a corresponding angle is required when grinding the ferrule end, which further leads to high difficulty in controlling the processing technology of the single-fiber bidirectional transceiver integrated components.

Among them, a ferrule hole 11 is provided inside the ferrule end 1, and the ferrule hole 11 is used to accommodate an optical fiber to facilitate optical coupling. A first guide hole 12 is provided inside the component, and one end of the first guide hole 12 is connected to the ferrule hole 11. A second guide hole 22 is provided inside the insertion end 2, and the second guide hole 22 is connected to the other end of the first guide hole 12, so as to extend the optical fiber from the second guide hole 22 of the insertion end 2 through the first guide hole 12 to the ferrule hole 11 of the ferrule end 1. In this embodiment, the ferrule hole 11 of the ferrule end 1, the first guide hole 12 and the second guide hole 22 are coaxial, and the holes of the ferrule hole 11, the first guide hole 12 and the second guide hole 22 of the ferrule end 1 gradually become larger to ensure that the optical fiber can be well connected to the ferrule end 1 from the insertion end 2. In this embodiment, the component horizontally connects the optical fiber insertion end 2 with the ferrule end 1, and at the same time sets the ferrule hole 11 of the ferrule end 1, the first guide hole 12 and the second guide hole 22 to different apertures, so that the specifications of the optical fiber itself can be reduced, and the influence of refraction or reflection in the optical fiber can also be reduced. In addition, the overall processing technology of the component is simple, and the core insertion process is convenient. That is, it effectively solves the disadvantage of the difficulty in controlling the processing technology of the single-fiber bidirectional transceiver integrated component in the prior art.

[0032] In this embodiment, in order to reduce the influence of light reflected or refracted by the optical fiber in the assembly, the inner diameters of the second guide hole 22, the first guide hole 12 and the core insertion hole 11 are gradually reduced. That is, in this embodiment, a first conversion port (not marked in the figure) is provided at the joint of the second guide hole 22 and the first guide hole 12, and the first conversion port is in the shape of a cone hole, the large aperture of the first conversion port is connected to the second guide hole 22, and the small aperture of the first conversion port is connected to the first guide hole 12, which can reduce the influence of light reflected or refracted in the optical fiber on the one hand, and facilitate the fiber insertion work on the other hand.
