Which limitation impacts long-distance fiber amplifiers reliant on Stimulated Brillouin scattering?

💡 Explanation

Stimulated Brillouin scattering requires a relatively long coherence length of the pump. Because without sufficient coherence, the interaction which amplifies the signal degrades, therefore the maximum achievable gain decreases, rather than limits regarding phonon lifetime broaden response.
