Unlike other optical amplifiers, such as erbium-doped fiber amplifiers (EDFAs), Raman amplifiers utilize the nonlinear interaction between the optical signal and the vibrational modes of the medium, typically a fiber optic cable, to achieve amplification. This technology is crucial in modern telecommuni..."
