本文尝试用数字光纤通信用激光器代替模拟光纤通信用激光器,通过加入温度控制,预失真补偿电路等线性补偿方法以及通过输入端加入AGC,固定衰减器等动态范围补偿的方法,使数字光纤通信用激光器在线性度以及动态范围两方面得到很大的提高,达到模拟光纤通信用激光器的水平,完全可以应用于短波,超短波以及微波模拟光纤通信中。 This paper attempts to replace the optical fiber communication laser with digital optical fiber communication laser by adding linear compensation methods such as temperature control and predistortion compensation circuit and adding dynamic range compensation such as AGC and fixed attenuator at the input end to make digital optical fiber communication Laser linearity and dynamic range of the two greatly improved to achieve the level of analog optical fiber communications lasers can be completely used in shortwave, ultrashortwave and microwave optical fiber communication.
