Optical module

An optical module, comprising:

• a circuit board;
• and
• an optical transmitter device, the optical transmitter device comprising:
• a substrate;
• a spacer disposed on the substrate and electrically connected to the circuit board;
• a laser chip disposed on and electrically connected to the spacer, and configured to emit an optical signal;
• an optical fiber adapter disposed on the substrate and is located in a light exit direction of the laser chip, and the optical fiber adapter is configured to fix an internal optical fiber, the internal optical fiber being configured to transmit the optical signal emitted from the laser chip to an outside of the optical module;
• and
• a focusing lens disposed between the laser chip and the optical fiber adapter and configured to converge light emitted by the laser chip to the optical fiber adapter,
• wherein a light incident surface of the optical fiber adapter has a first inclination angle with respect to an axis of the optical fiber adapter, the axis of the optical fiber adapter being located in a plane parallel to the substrate, and the optical fiber adapter is obliquely disposed on the substrate such that an axis of the internal optical fiber has a second inclination angle with respect to an optical axis of the focusing lens;
• wherein the optical axis of the focusing lens is in the same plane or approximately in the same plane as the axis of the optical fiber adapter.
