The impulse response of a step index multimode optical fiber excited by a Lambertian source is presented using the power flow equation. The dependence of the response on both the coupling coefficient and the attenuation coefficient is illustrated. It is shown that the width of the impulse response is proportional to the square root of the fiber length.
利用功率流方程给出了由朗伯光源激发的阶跃折射率多模光纤的脉冲响应。阐述了该响应与耦合系数和衰减系数的相关性。结果表明，脉冲响应的宽度与光纤长度的平方根成正比。
