Optical module

An optical module, comprising:

• a shell;
• a circuit board located in the shell;
• a light-receiving device disposed on the circuit board and electrically connected to the circuit board;
• an optical fiber socket that is configured to provide an optical port of the circuit board;
• and
• an optical fiber ribbon, an end thereof being connected to the optical fiber socket, and another end thereof being optically connected to the light-receiving device;
• wherein, the light-receiving device includes:
• a light-receiving chip disposed on a surface of the circuit board and having a photosensitive surface that is away from the circuit board;
• and
• a focusing lens disposed opposite to the photosensitive surface of the light-receiving chip and configured to converge light transmitted by the optical fiber ribbon to the photosensitive surface of the light-receiving chip.
