Optical module

An optical module, comprising:

• a shell;
• a circuit board disposed in the shell;
• a light-emitting component disposed in the shell, the light-emitting component being electrically connected with the circuit board and configured to generate an optical signal;
• a first optical fiber adapter;
• a first internal optical fiber, an end of the first internal optical fiber being connected to the first optical fiber adapter;
• an optical fiber connector optically connected to the light-emitting component and wrapping another end of the first internal optical fiber;
• and
• an optical fiber ferrule, wherein the optical fiber ferrule is disposed in the optical fiber connector and wraps the another end of the first internal optical fiber;
• the optical fiber ferrule is a transparent material member;
• and an end surface of the another end of the first internal optical fiber is inclined relative to the bottom wall;
• wherein the first internal optical fiber and the optical fiber connector are transparent material members, and light transmittance of the first internal optical fiber is different from light transmittance of the optical fiber connector;
• wherein the light-emitting component includes a light-emitting housing, and the light-emitting housing includes a bottom wall and a concave groove;
• the concave groove is disposed on the bottom wall, and is recessed downward relative to the bottom wall;
• the optical fiber connector is disposed on the bottom wall, and a portion of the optical fiber connector is located above the concave groove;
• and an orthogonal projection of the another end of the first internal optical fiber on the bottom wall is located within the concave groove;
• the light-emitting housing further including:
• a first side wall being a side wall of the light-emitting housing proximate to the first optical fiber adapter;
• a through hole disposed in the first side wall;
• and
• an assembling groove disposed on the bottom wall and communicated with the through hole;
• the assembling groove including a limiting wall, and the limiting wall being a side wall of the assembling groove away from the through hole;
• and the optical fiber connector being disposed in the assembling groove through the through hole;
• the light-emitting component further including:
• a light-emitting assembly disposed in the light-emitting housing and configured to emit the optical signal;
• and
• a lens disposed in the light-emitting housing and located on a light-emitting path of the light-emitting assembly;
• the lens being configured to converge the optical signal emitted by the light-emitting assembly, and
• wherein a portion of an end of the optical fiber ferrule abuts against the limiting wall, so that the end of the optical fiber ferrule is located on the light-emitting path of the lens, and the optical signal converged by the lens enters the another end of the first internal optical fiber.
