Optical fiber dispersion compensation
Abstract
A module, for upgrading optical fiber systems, includes an appropriate length of Dispersion Compensating Fiber (DCF) for nulling chromatic dispersion, together with a pump (5), which uses Stimulated Raman Scattering for amplifying signal in the DCF, thereby compensating for power loss associated with the DCF.
