A realization approach of optical 3R regeneration based on four-wave mixing in dispersion-shifted fibers

Abstract

Signal regeneration is one of the critical functions for the future long-haul transmission distances in all-optical networks. In this paper, the different realization approaches of all optical regenerators are also presented. The theory of FWM is discussed and the application of FWM in Dispersion-Shifted Fiber based optical 2R regenerator is introduced. A realization approach of Optical 3R Regeneration based on Four Wave Mixing will be proposed.
