Packaging method of optical module

The invention relates to the technical field of laser engineering, and discloses a packaging method of an optical module. The optical module comprises an optical receiving unit, an optical transmitting unit and a tube shell, and the packaging method of the optical module comprises the following steps: S11, independently packaging and electrifying the optical receiving unit; s12, the light emitting unit is independently packaged and is powered on; s2, carrying out active coupling on the light receiving unit and the light emitting unit in the tube shell and fixing the light receiving unit and the light emitting unit in the tube shell; and S3, carrying out airtight packaging on the optical module. According to the invention, the light emitting unit and the light receiving unit are independently subjected to the power connection test, and the test convenience is improved; in the optimal working state of the optical module, coupling of the optical transmitting unit and the optical receiving unit is completed, high
