The invention discloses a method and a device for an optical transmission terminal of an optical transceiving device. A square metal part is fixed in a coupling and positioning device, a circular hole capable through which light can penetrate is arranged upwards and current is input into a laser transmitting element; a cylindrical metal part is arranged on the square metal part, one end of the cylindrical metal part is attached to the surface of the circular hole of the square metal part, and a light receiving plug is inserted into the other end; an adjusting screw of the coupling and positioning device is rotatably screwed to eject a conical surface on an outer ring of the cylindrical metal part and the optical power output by the light receiving plug is checked; when the optical power reaches a preset value, the rotatable screwing of the adjusting screw is stopped; and circular edges of the attaching surface are welded by spot welding of a laser welder. With the technical scheme, the optical power output of
