Abstract

The invention discloses an optical module, which belongs to the communication field. The optical module includes: a circuit board, a lens assembly, a laser chip, and a photodetection chip. The laser chip and the photodetection chip are respectively mounted on the surface of the circuit board; the lens assembly is covered by the laser Above the chip and the light detection chip; the lens assembly has a transmitting lens, a receiving lens, a reflective surface, a first fiber optic lens and a second fiber optic lens; the transmitting lens and the receiving lens have different focal lengths; the The first optical fiber lens has the same focal length as the second optical fiber lens; the emitting lens emits the light emitted by the laser chip to the first optical fiber lens through the reflecting surface; the light from the second optical fiber lens passes through The reflective surface is then directed to the light detection chip through the receiving lens. The invention can meet the demands of different products.

Description

technical field [0001] The invention relates to the communication field, in particular to an optical module. Background technique [0002] The optical module has the functions of transmitting and receiving optical signals. The optical module includes optical components such as a laser and a detector. The laser can generate light, and the optical module converges the light into the first spot on the optical fiber and injects it into the optical fiber; the optical module also converges the light from the optical fiber on the detector. into a second light spot and enter the detector. [0003] The diameter S of the first light spot that the optical module converges on the optical fiber 0 , the laser emission size S 1 , the diameter S of the second light spot converged on the detector 2 And the diameter D of the optical fiber satisfies the following relationship: S 0 *S 2 = S 1 *D. Among them, the emission size S of the laser 1 Usually 20um, fiber diameter D is usually 5...
