fiber optic dispersion 光纤散射 Two types of dispersion——modal and chromatic——occur in optical fibers. M odal dispersion is the spreading of light as it takes different paths (travels i n different modes) along the fiber. Chromatic dispersion depends on the wavelength or color of the light. 光纤中发生的散射,有两类:模态散射和色散。模态散射是当光沿光纤以不同的路径 (以不同的方式)传播时光的扩散。色散则与光的波长或颜色有关。 |
