AI Technical Summary
Existing optical module bias current control technology cannot integrate aging and thermal coupling state perception under service-carrying conditions, resulting in excessive bias current compensation, increased power consumption of the drive circuit and a vicious cycle, making it impossible to achieve high-precision detection and dynamic adjustment.
A real-time monitoring and adaptive optimization system is adopted. The bias current value is obtained through the acquisition and judgment module. A joint prediction model is constructed by combining the aging health factor H and the thermal coupling factor G. A dynamic search window is set, a scanning sequence is executed and diagnostic optimization is performed, and finally the bias current setting value of the laser driver chip is updated.
It enables differentiated optimization under both business-sensitive and non-sensitive conditions, reduces the risk of business error codes, improves the accuracy of bias current prediction and scanning search efficiency, and avoids problems such as performance curve sampling distortion and excessive optimization time.
