Optical module

An optical module, comprising:

• a circuit board;
• a light transmit-receive device disposed on the circuit board, and the light transmit-receive device being configured to emit a plurality of channels of first optical signals, receive a plurality of channels of second optical signals from outside of the optical module, and convert the plurality of channels of second optical signals into a plurality of channels of electrical signals;
• a data processor disposed on the circuit board, wherein the data processor includes:
• a reverse gearbox connected to the light transmit-receive device, and the reverse gearbox being configured to receive a first high-speed electrical signal from the circuit board, decode the first high-speed electrical signal into a plurality of channels of first low-speed electrical signals, and the plurality of channels of first low-speed electrical signals driving the light transmit-receive device to emit the plurality of channels of first optical signals;
• and
• a gearbox connected to the light transmit-receive device, and the gearbox being configured to receive a plurality of channels of second low-speed electrical signals output by the light transmit-receive device, encode the plurality of channels of second low-speed electrical signals into a second high-speed electrical signal, and transmit the second high-speed electrical signal to the circuit board;
• the light transmit-receive device includes:
• a first laser array disposed on the circuit board, and the first laser array being configured to emit the plurality of channels of first optical signals driven by the plurality of channels of first low-speed electrical signals;
• a first detector array disposed on the circuit board, and the first detector array being configured to receive the plurality of channels of second optical signals from outside of the optical module, and convert the plurality of channels of second optical signals into the plurality of channels of electrical signals;
• and
• a first lens assembly covering the first laser array and the first detector array, and the first lens assembly being configured to change a propagation direction of optical signals incident into inside of the first lens assembly.
