摘要	An optical transmission system wherein light is transmitted from a transmitter to a receiver by at least one transmission optical fiber. The system includes a dispersion transformer which receives light from one of the components, compensates for or transforms the delay distortion of the various wavelengths transmitted through the system, and provides the next component in the system with a compensated or transformed light beam. The dispersion transformer comprises means for receiving light from one of the components and dispersing/separating the light into a plurality of spatially separated beams which are directed onto the endface of a multimode optical fiber. The position of each beam on the endface of the mutimode fiber is a function of the velocity with which the light that forms the beam propagates through the transmission optical fiber. The multimode fiber is characterized by a refractive index profile and a shape which are such that the modes excited therein are progagated therethrough with appropriate delays to generate an output pulse of desired width. Dispersion can be reduced or increased. Light emaninating from the multimode fiber is coupled to the next adjacent component of the system.
其他摘要	一种光传输系统，其中光通过至少一根传输光纤从发射器传输到接收器。该系统包括色散变换器，其接收来自其中一个组件的光，补偿或转换通过系统传输的各种波长的延迟失真，并为系统中的下一个组件提供补偿或变换的光束。色散变换器包括用于接收来自其中一个部件的光并将光分散/分离成多个空间分离的光束的装置，这些光束被引导到多模光纤的端面上。每个光束在多模光纤端面上的位置是形成光束的光传播通过传输光纤的速度的函数。多模光纤的特征在于折射率分布和形状，使得其中激发的模式以适当的延迟通过其前进，以产生所需宽度的输出脉冲。可以减少或增加分散。从多模光纤发出的光耦合到系统的下一个相邻组件。
