Optical module

An optical module, comprising:

• an upper shell and a lower shell, wherein the upper shell and the lower shell provide a wrapping cavity with two openings, one opening is an electrical port, and another opening is an optical port;
• a circuit board, wherein the circuit board is located in the wrapping cavity, a surface of a tail end of the circuit board has a connecting finger, and the connecting finger is located in the electrical port;
• a base, wherein the base is located on the circuit board or in a through hole of the circuit board;
• a laser assembly, wherein the laser assembly is located on the base and electrically connected to the circuit board, and is configured to provide first light;
• and
• a silicon optical chip, wherein the silicon optical chip is located on the base and electrically connected to the circuit board, and is configured to receive the first light, and modulate the first light to convert a first electrical signal into a first optical signal, and is further configured to receive a second optical signal from an outside of the optical module and convert the second optical signal into a second electrical signal.
