Abstract
(EN)
The invention discloses an optical module. The optical module comprises a circuit board, a laser emitter and a first laser receiver. The surface of the circuit board is provided with a golden finger,a control chip, a first driving chip and a second driving chip. The first driving chip and the emission pin of the golden finger are connected. The second driving chip and the control chip are connected. The first driving chip and the second driving chip drive the laser emitter in a time-sharing manner to generate the laser of a first wavelength. The laser enters into an external optical fiber. The emission pin provides emission data to the first driving chip. The first laser receiver receives the reflected light of the first wavelength from the external optical fiber. The first driving chip and the second driving chip share the laser emitter so that an optical module function and an effect that the laser emitters emit light in the function can be realized; and one laser can be saved, which is good for reducing the size of the optical module and decreasing the packaging size of the optical module.
