| Zusammenfassung: | The invention discloses an optical module, which comprises a circuit board and a light emitting device. The light emitting device comprises the following components of: a TO tube seat; a TO tube cap arranged on the TO tube seat in a covering manner; a laser which is arranged on the surface of the TO tube seat and used for emitting signal light beams, and the light emitting direction of the laser is not consistent with the light transmitting direction of the TO tube cap; a reflector which is provided with a bottom plateau, a top plateau and an inclined plane, wherein the bottom plateau is fixed on the TO tube seat, and the inclined plane is used for reflecting the signal light beams from the laser, so that the light emitting direction of the reflected signal light beams is consistent with the light transmitting direction of the TO tube cap; a lens which is arranged on the surface of the top plateau of the reflector and is used for converging the reflected signal light beams; and a photodiode which is arranged |
