Abstract :
The light propagating in a single-mode optical fibre is found to be converted gradually into forward-scattered spontaneous Rayleigh-Brillouin power. The Brillouin component has a linewidth of -500 MHz and constitutes ~1/200 of the propagating power at 1.3 ¿m wavelength after 600 km. The measured backscatter-Brillouin shift coefficient is ¿0.15 GHz/wt% GeO2.
