Optical module debugging method and device, electronic equipment and storage medium

Abstract

The invention relates to an optical module debugging method and device, electronic equipment and a storage medium, and belongs to the technical field of optical communication. The optical module debugging method comprises the steps of obtaining the slope and intercept of a characteristic relation curve corresponding to the laser current and the light emitting power of an optical module, and obtaining the coupling mode of a driving circuit and a laser in the optical module; calculating bias current and modulation current corresponding to the debugged target average optical power and target extinction ratio according to the slope, the intercept and a preset formula corresponding to the coupling mode; testing whether the average optical power under the bias current and the modulation currentis within an error range allowed by the target average optical power or not; if so, testing whether the extinction ratio under the bias current and the modulation current is within the error range allowed by the target extinction ratio or not; and if so, determining the bias current and the modulation current as required parameters. According to the method, the final debugging parameters can be obtained with a large probability only through a small number of steps, repeated cyclic debugging and testing are avoided, and the debugging efficiency is greatly improved.

Description

technical field [0001] The application belongs to the technical field of optical communication, and in particular relates to an optical module debugging method, device, electronic equipment and storage medium. Background technique [0002] Average optical power (Average optical power, AOP) and extinction ratio (Extinction Ratio, ER) are the two most critical indicators of optical modules. Due to the different luminous efficiencies of lasers, these two indicators need to be individually debugged during the production of each optical module. The debugging methods of these two indicators have a great impact on the production efficiency of optical modules. Therefore, advanced and efficient debugging methods can greatly improve the production efficiency and capacity of optical modules. [0003] For directly modulated laser optical modules, AOP and ER are affected by the bias current (IBIAS) and modulation current (IMOD) provided by the laser drive circuit. The debugging process...
