0.4 dB/km, 1.4μm, 6μm, 550MHz. Find threshold optical power for stimulated Raman scattering.

0.4 dB/km, 1.4μm, 6μm, 550MHz. Find threshold optical power for stimulated Raman scattering. Correct Answer 1.18 W

The threshold optical power stimulated Raman scattering is given by- PR = 5.9*10-2d2λαdB Where, PR = optical power for Raman scattering d = diameter of core λ = wavelength αdB = attenuation.
