Реферат: Abstract of the Disclosure 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 end-face of the multimode 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 propagated 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.
