Debugging method for optical power and extinction ratio of optical module

The invention discloses a debugging method for optical power and extinction ratio of an optical module. According to the method, a digital resistor is adjusted twice so that the optical power of the optical module can be adjusted to be within the required specification only by three steps; on the basis of optical power adjustment, the extinction ratio can be adjusted to be within the required specification only through one step. The method comprises detailed algorithms and processes, the adjustment speed of the optical power and the extinction ratio in the optical module production process canbe increased, the utilization rate of production equipment is increased, and the yield of the optical module in unit time of a production line is increased. 本发明公开了一种光模块光功率及消光比的调试方法，所述方法通过调节数位电阻两次，只需三步可将光模块的光功率调整至需要规格内，在光功率调节基础上只需一步可将消光比调整至需要规格内，本发明方法包括详细的算法及流程，可以提升光模块生产过程中光功率及消光比的调整速度，提高生产设备的利用率以及提升产线单位时间的光模块的产量。
