Stimulated Brillouin scattering in high-order mode fibers employed in dispersion management modules

Dispersion management modules based on large effective area, relatively short high-order mode fibers are experimentally shown to have high input power threshold to stimulated Brillouin scattering. Theoretically, they behave similarly to the LP/sub 01/ mode of dispersion compensation fibers but with a larger effective area and shorter effective length. The resulting /spl sim/5-dB higher threshold further strengthens the viability of full dispersion and slope compensation without significant input power limitation.
