A method for spectral equalization of high frequency spectrally broadband signals transmitted through an optical fiber. The broadband signal input is first dispersed by a grating. Narrow spectral components are collected into an array of equalizing fibers. The fibers serve as optical delay lines compensating...http://www.google.fr/patents/US4405199?utm_source=gb-gplus-shareBrevet US4405199 - Method for enhancing signals transmitted over optical fibers
