Question 130/336

If a weak signal light and a strong pump light are transmitted simultaneously in an optical fiber, and the wavelength of the weak signal light is within the Raman gain bandwidth of the pump light, the energy of the strong pump light is combined into the oscillation mode of the silicon material of the optical fiber through stimulated Raman scattering (SRS), and then emitted at a longer wavelength, which is the wavelength of the signal light, thereby amplifying the weak signal light and obtaining Raman gain.

A. TRUE

B. FALSE
