摘要	The invention presents a method that calibrates the laser optical power (202) in a continuous manner without disrupting the flow of information in the optical communications link. The method utilizes knowledge of the measured value of the laser optical power (202) and makes necessary adjustments to optimize the values of the Extinction Ratio, Bit Error Rate and to compensate for aging. The method utilizes knowledge of the temperature from a sensor (114) and mathematical models, which contain parameters which are updated for a specific laser configuration.
其他摘要	本发明提出了一种以连续方式校准激光光焦度（202）而不破坏光通信链路中的信息流的方法。该方法利用激光光功率的测量值的知识（202）并进行必要的调整以优化消光比，误码率的值并补偿老化。该方法利用来自传感器（114）的温度和数学模型的知识，该数学模型包含针对特定激光器配置更新的参数。
主权项	A method to compensate for the effects of temperature on laser power in an optical transceiver, wherein the method is performed without disrupting communication comprising the steps of: performing an initial factory calibration; updating the value of the Bias Current IBIAS2 (306) at the new temperature T2 using a temperature drift model; adjusting the bias current generator (102) with a new value; updating the value of the Modulation current IMAVE2 (310) at the new temperature T2 using a temperature drift model; and adjusting the bias current generator (102) with a new value.
