Abstract

Optical pathways along optical fibers, including multiple cores or multiple modes, are arranged with positive and negative dispersion characteristics. Coupling or connecting mechanisms regulate relative lengths of travel between the pathways having different dispersion characteristics so the total dispersion of the combined pathways approaches zero dispersion over a range of signal wavelengths intended for transmission.
