以线性信道输入、输出脉冲与光纤脉冲响应均方宽度关系讨论了脉冲展宽对传输距离的限制,改进了已有的近似公式,给出了供工程查用的计算曲线。
The relationship between the pulse width and the mean square width of the impulse response of the fiber is discussed. The extension of the pulse width to the transmission distance is discussed. The existing approximate formulas are improved and the calculation curve for the engineering check is given.
