运用现代先进的数字光纤通信用激光器来代替以往使用的模拟光纤通信用激光器,通过使用加入温度控制、预失真补偿电路等线性补偿形式,并使用在输入端添加AGC和固定衰减器等动态性质的补偿方法,进而有效的使数字光纤通信用激光器的在线性度和动态范围得到显著提高,实现模拟光纤通信用激光器具有的水平,并能够应用在短波、微波和超短波的模拟光纤通信中。
The use of modern advanced digital optical fiber communications laser instead of the old analog optical fiber communications lasers, through the use of adding temperature control, pre-distortion compensation circuit and other linear compensation and the use of the input to add AGC and fixed attenuator and other dynamic properties Compensation method to effectively improve the linearity and dynamic range of the digital optical fiber communication laser and realize the level of the analog optical fiber communication laser and can be applied to the analog optical fiber communication of the short wave, the microwave and the ultrashort wave.
