Abstract

This disclosure provides an optical module including a lens assembly and an optical fiber holder. One end of the lens assembly is provided with a wrapping cavity, in which a second lens is disposed. An optical fiber is inserted in the optical fiber holder, with a gap formed between a fiber end-face of the optical fiber and the second lens. The fiber end-face of the optical fiber and a first end face of the optical fiber holder are inclined surfaces. The wrapping cavity includes a stop protrusion. A surface of the stop protrusion facing towards the optical fiber holder is an inclined stop surface, which is in contact with the first end face. The stop surface and the first end face of the optical fiber holder are inclined surfaces, achieving connection between the optical fiber holder and the lens assembly along a length direction of the lens assembly.
