We present results for power transmitted when a typical multimode optical fiber is excited by a Lamber-tian source. Power attenuation is due to absorbing core and cladding materials and radiation loss due to reflections from the circular cross section. Radiation loss is responsible for a significant power reduction (20-25% for Lambertian source) over distances much less than those for which material absorption is important.
我们给出了典型多模光纤由朗伯光源激发时的功率传输结果。功率衰减是由于纤芯和包层材料的吸收以及圆形横截面反射导致的辐射损耗。在远小于材料吸收起重要作用的距离上，辐射损耗会导致显著的功率降低（对于朗伯光源为20 - 25%）。
