| 摘 要： | 数字光纤接收机的灵敏度计算与其输入光脉冲波形直接相关。本文从工程应用角度考虑,研究了数字光纤接收机输入光脉冲的函数逼近问题,导出了用高斯函数近似接收机实际输入光脉冲波形时,发送光脉冲的占空比、码速率和光纤带宽之间应满足的关系,并给出了高斯波形参数的取值范围。

| Abstract: | The sensitivity of a digital optical fiber receiver is directly relevant to the optical pulse shape at the input of the receiver,and varies with the optical pulse.This paper investigates the function approximation of the optical pulse waveforms at the input of the optical receivers from the point of vies of the engineering application.The relationships among the duty cycle,the bit rate and optical fiber bandwidth can be obtained when the real optical pulse waveforms at the input of the receiver are approximated by Gaussian function and the range of the parameter for Gaussian shape can be also given. |
